Core Conclusions and Key Numbers
Mid-layer summary translates tool output into decision statements. Each card is tied to explicit source-backed evidence or marked uncertainty.
Tool-first layout matches mixed do/know intent
Users can run a 100 kg suitability check immediately, then review evidence and risk boundaries without leaving this URL.
Route signal is balanced do/know (0.500 / 0.500), so interaction and explanation are both required.
100 kg class is viable only under explicit contact assumptions
Surface roughness, geometry, orientation, and material behavior can remove margin long before nominal class is reached.
HSE states magnetic devices are not general-purpose and highlights difficult cases such as rough castings and thin sheet.
Powered-magnet safeguards are now separated from permanent-magnet assumptions
The page now separates powered-system warning/hold requirements from permanent-lifter claims, and marks unsupported numeric claims as pending confirmation.
HSE PDF provides >20 kg SWL warning/hold safeguards for powered systems; open sources here do not provide a stable numeric FoS baseline for permanent manual lifters.
Regulatory scope boundaries are explicit
OSHA, HSE, and ASME references are mapped to when they apply and when they do not, so the checker is not treated as legal sign-off.
Applicability matrix now includes OSHA 1910.179, OSHA 1910.184, HSE guidance, and ASME B30.20-2025 scope.
Audience split is explicit to avoid misuse
Operations and procurement teams can use this page directly, while out-of-scope cases route to engineering fallback paths.
Suitability matrix and scenario layer include “not fit” lanes with minimum executable alternatives.
Supplier screening now has explicit pass/fail evidence gates
The page now separates “quote looks good” from “evidence package is verifiable” before purchase order lock.
HSE supplier duties, OSHA record/test rules, and ILAC verification pathways are mapped to concrete pass/fail checks.
Target nominal class
100 kg
Primary keyword lane is small-capacity permanent magnetic lifter screening.
Imperial conversion

Derived from NIST SI conversion reference for 1 lb = 0.4535924 kg.
HSE guidance freshness
Updated Oct 29, 2024
Magnetic lifting devices page rechecked on Apr 26, 2026.
HSE powered-magnet trigger
>20 kg SWL
Battery-fed systems above this threshold require low-battery warning logic.
HSE warning timing
>=10 min
Warning should occur at least 10 minutes before battery supply reaches release threshold (not a fixed public 50% rule).
HSE standby hold cue
SWL for >=10 min
For externally supplied powered systems over 20 kg SWL, standby battery should hold SWL for at least 10 minutes.
Permanent-lifter FoS (public-source status)
Pending confirmation
No reliable open-source numeric FoS baseline was confirmed in this page source set; supplier/test evidence is required.
HSE travel-height cue
<=1.5 m where practicable
Loaded magnets should be moved at lowest practical height.
HSE temperature boundary cue
~700°C
HSE notes ferrous materials cease magnetic behavior around this range.
OSHA sling-angle caution
<30° from horizontal avoid
Low-angle rigging amplifies force and raises loss-of-control risk.

Stage2 SEO + GEO Audit and Verification Gate
Findings are scored by severity and patched in-page. Release gate requires blocker=0 and high=0 after fixes.
| Gap | Impact | Patch | Severity |
|---|---|---|---|
| Powered-system safeguard text previously implied a fixed “50% battery” rule. | Could cause incorrect procurement acceptance criteria and false pass/fail interpretation. | Reworded to verified formulation: warning at least 10 min before supply reaches release threshold; keep standby-hold requirement as separate statement. | high |
| Permanent-lifter FoS numeric baseline was stated without stable open-source backing. | Could be misread as a hard public rule and create overconfident release decisions. | Converted to explicit uncertainty: “Pending confirmation / no reliable public numeric baseline in this source set.” | high |
| Regulatory scope boundaries were mixed (UK HSE, US OSHA, ASME scope) without explicit applicability. | Teams could treat guidance outside their legal or equipment context as if universally mandatory. | Added a dedicated applicability matrix with “applies / not applicable / action gate” columns. | high |
| Tool input model lacked direct rigging-angle entry despite OSHA low-angle caution. | A pass result could hide high-risk sling geometry if angle was not entered explicitly. | Added sling-angle input with boundary validation and <30° out-of-scope gate in checker logic. | high |
| Cycle and temperature multipliers looked like hard standards. | Could be misread as regulatory thresholds instead of model heuristics. | Method table now includes evidence-level tags and tool numbers panel explicitly marks heuristic factors. | medium |
| Unknown areas around public benchmark data and standard-edition mapping needed stronger labeling. | Overconfidence risk remained if users assumed complete public evidence coverage. | Expanded known/unknown matrix with explicit “pending confirmation / no reliable public dataset” actions. | medium |
| Standards/version timeline was not explicit for EN 13155 drift and EU 2027 transition. | Teams could lock RFQ or compliance text to outdated editions and miss transition gates. | Added standards timeline table with edition drift, legal date, decision impact, and minimum action per item. | medium |
| Supplier qualification lacked a document-level pass/fail gate. | Lowest-price quotes could pass initial review without verifiable technical evidence or authentic records. | Added Supplier Evidence Gate table linking HSE/OSHA/ILAC requirements to explicit pass/fail procurement checks. | high |
| Certificate/test-report authenticity path was implied but not operationalized. | Teams could accept fake or out-of-scope certificates and discover gaps only at FAT/SAT or audit. | Added accreditation-verification lane (ILAC signatory checks and traceability requirements) plus FAQ execution guidance. | high |

Intent Pattern and Anti-Duplication Angle
This section records why one hybrid URL is used: tool completion first, then trust-building report depth.
| SERP pattern | User need | Page response | Evidence |
|---|---|---|---|
| Query cluster mixes product-listing intent with “is 100 kg enough” decision intent. | Immediate fit check and clear “what can break this decision” explanation. | Tool appears first; report layer then explains assumptions, evidence, and risk triggers. | Intent-router signal (ambiguous, low confidence) and observed keyword overlap with product pages. |
| User language alternates between “100 kg lifting magnet” and “100kg magnetic lifter”. | Single canonical page without duplicate content competition. | This URL keeps one canonical decision flow and links to adjacent high-capacity pages only for escalation. | OpenSpec change scope and anti-duplication requirement for dedicated angle. |
| Many external pages emphasize nominal load but under-communicate boundary failures. | Decision-safe guardrails before RFQ and site rollout. | Risk matrix, known/unknown table, and scenario fallback paths are integrated in the same page. | Hybrid content-depth checklist requirement and stage1b gap patches. |
| “100kg lifting magnet supplier” queries often collapse product choice and supplier qualification into one click. | A fast way to reject weak quote packages before engineering time is consumed. | Supplier evidence gate now lists mandatory records, authenticity checks, and minimum fallback path per failure mode. | HSE supplier duties + OSHA documentation obligations + ILAC accreditation-verification guidance. |
Suitable audience
| Profile | Recommendation | Reason | Minimum path |
|---|---|---|---|
| Workshop teams moving repeat flat steel pieces below 80-90 kg | Good fit | Typical assumptions align with checker baseline when contact quality and material are stable. | Run checker -> verify boundary notes -> submit inquiry with proof/inspection expectations. |
| Procurement teams comparing 100 kg and 200 kg models | Good fit | Tool + comparison tables quickly separate shortlist options and required evidence depth. | Use comparison matrix -> request vendor evidence package -> lock quote terms. |
| Mixed-material handling with uncertain ferromagnetic behavior | Conditional | Material uncertainty lowers confidence and can invalidate nominal assumptions. | Treat result as screening only; require material confirmation and representative tests. |
| Vertical-face, high-temperature, or thin-stock critical handling | Not fit | Boundary-critical scenarios exceed quick-check assumptions for 100 kg class release. | Escalate to engineering method review and alternative gripping architecture. |
Method Logic and Decision Flow
The tool model is transparent: each factor has baseline, degradation signal, and explicit policy response.
Factor model table
| Factor | Baseline | Degrade signal | Tool policy | Source | Evidence level |
|---|---|---|---|---|---|
| Surface/contact quality | Clean and dry contact surface | Scale, paint, oil, or visible air gap | Apply derating multiplier and boundary warning in output panel. | HSE magnetic lifting guidance and operating limitations | Regulatory guidance |
| Load geometry | Flat plate contact profile | Round bar/pipe or small contact footprint | Increase effective demand and reduce confidence band. | HSE guidance + product-side behavior patterns | Regulatory guidance |
| Handling orientation | Horizontal transfer | Tilt/turn or vertical-face handling | Raise severity and route to conditional/not-fit lanes. | HSE transport cautions and site method controls | Regulatory guidance |
| Temperature exposure | <=60°C routine condition | >80°C elevated and >150°C boundary-critical | Increase demand factor and add explicit caution notes; high-heat cases move to out-of-scope. | HSE temperature cautions; OSHA thermal thresholds for chain slings only | Regulatory guidance |
| Cycle intensity | <=12 lifts/hour | High-cycle handling over 25 lifts/hour | Apply internal cycle factor and tighten recommendation threshold (screening use only). | Internal reliability heuristic; no harmonized public threshold | Internal heuristic |
| Rigging geometry | >=45° from horizontal where practicable | <45° caution, <30° boundary-critical | Set <30° to out-of-scope and require route redesign or qualified approval. | OSHA Safe Sling Use (alloy steel chain slings) | Regulatory guidance |
Applicability Boundaries and Counterexamples
This section separates where each standard/guidance applies and records high-risk counterexamples that should not be forced into a 100 kg quick-check lane.
Applicability matrix
| Requirement | Applies when | Not applicable | Action gate | Source |
|---|---|---|---|---|
| HSE: >20 kg SWL powered magnets need warning/hold safeguards | Battery-fed or externally supplied powered magnetic lifting systems in HSE guidance scope. | Purely permanent/manual lifters with no electrical power path. | Collect warning-timing and standby-hold evidence before operational release. | HSE guidance PDF |
| HSE supplier duty (including second-hand supply) under Section 6 HSWA | A supplier recommends or supplies magnetic lifting equipment into a work context covered by HSE guidance. | Not a substitute for end-user site controls; this duty does not remove operator obligations. | For second-hand equipment, require the latest thorough-examination details and intended-use data before quote acceptance. | HSE magnetic lifting devices page |
| OSHA 1910.179 magnet controls (switch enclosure + discharge path) and crane inspections | Overhead/gantry crane operations under U.S. OSHA jurisdiction. | Non-U.S. sites or non-crane handling tools outside 1910.179 scope. | Confirm jurisdiction, equipment category, and inspection documentation before quoting compliance. | OSHA 29 CFR 1910.179 |
| OSHA 1910.184 thermal limits and proof-test records for alloy chain slings | Chain slings are part of rigging path around the magnet workflow. | Not a direct magnetic flux limit and not a substitute for magnet-specific testing. | Separate sling controls from magnet controls in SOP and vendor evidence requests. | OSHA 29 CFR 1910.184 |
| BS EN 13155 edition citation must match current project governance baseline | RFQ/specification or declaration uses EN 13155 references for magnetic lifting attachments. | Projects without EN/BS reference obligations in contractual or jurisdictional scope. | Record exact edition in RFQ, supplier declaration, and FAT/SAT checklist before quote lock. | HSE page + BSI standard listing |
| EU Machinery Regulation (EU) 2023/1230 transition planning | Equipment is placed on EU market with CE obligations and transition window affects delivery/release timing. | Non-EU placements with no EU machinery compliance route in scope. | Map compliance path to Jan 20, 2027 switch date and avoid mixed Directive/Regulation claims. | EUR-Lex Regulation 2023/1230 corrigendum |
| ASME B30.20 below-the-hook device framework | Procurement or engineering references ASME governance for design/inspection/testing. | Catalog page alone is not a full normative requirement set. | Obtain licensed standard text and map clauses to FAT/SAT checklists. | ASME B30.20 catalog page |
Counterexample table
| Case | Why 100 kg lane fails | Minimum alternative | Source |
|---|---|---|---|
| Rough castings | HSE notes these are usually unsuitable because roughness prevents full contact. | Use mechanical gripping route or dedicated fixtures with verified contact mechanics. | HSE magnetic lifting devices page |
| Thin sheet handling | HSE states sheet metal can be difficult to lift due to thinness and weak coupling. | Use multiple magnets, lifting beams, or non-magnetic gripping architecture. | HSE magnetic lifting devices page |
| Mixed or weakly magnetic materials | HSE warns not all steels are magnetic enough; load may fall away during transfer. | Require material confirmation and representative pull-off tests before selection lock. | HSE magnetic lifting devices page |
| High-temperature ferrous loads | HSE notes ferrous materials cease to be magnetic around 700°C. | Switch to high-temperature compatible non-magnetic lifting method and thermal controls. | HSE magnetic lifting devices page |
| Loads grouped by banding straps | HSE permits this only if straps/chains are rated and marked with SWL for the load. | Use rated lifting assemblies with traceable SWL records. | HSE magnetic lifting devices page |
| Gas/liquid containers | HSE says these should not be lifted magnetically because movement can damage containment. | Use dedicated container lifting systems designed for sealed vessels. | HSE magnetic lifting devices page |
Supplier Evidence Gate (Pre-PO)
This gate converts regulation and accreditation references into pass/fail checks for a 100kg lifting magnet supplier decision.
Evidence package acceptance table
| Gate | Why it matters | Pass evidence | Fail signal | Source |
|---|---|---|---|---|
| Intended-use data captured before recommendation | HSE states supplier advice must be based on load/material/contact context, not nominal class alone. | RFQ includes material type, dimensions, thickness, profile, flatness/roughness, environment, and operating mode. | Supplier recommends model only from “100 kg” label without requesting application details. | HSE magnetic lifting devices page (points 12-14) |
| Powered-magnet safeguard evidence (>20 kg SWL lane) | HSE guidance requires warning/hold controls for powered systems over 20 kg SWL. | Documents show warning at least 10 minutes before release-threshold condition and standby hold evidence where applicable. | Supplier provides only a generic battery percentage statement with no release-threshold or hold test basis. | HSE safe-use PDF |
| U.S. crane magnet control path | For OSHA crane scope, magnet circuit controls and inspection cadence are explicit compliance gates. | Evidence package references enclosure/discharge controls plus frequent and periodic inspection plan. | No magnet-control details or no documented inspection cadence in quote package. | OSHA 29 CFR 1910.179 |
| Sling-path proof and inspection records | Rigging failures can invalidate otherwise acceptable magnet decisions. | New/repaired sling proof-test records are present and latest monthly inspection record is traceable. | No proof-test record or no recent inspection record in the supplied pack. | OSHA 29 CFR 1910.184 |
| Test-report authenticity + accreditation path | Unverifiable reports create hidden release and audit risk. | Testing body can be validated through ILAC-recognized accreditation route and report includes traceability chain. | Logo-only certificate with no verifiable accreditation route, scope, or metrological traceability details. | ILAC CAB verification page + ILAC P10 policy |
| Global quality-certificate verification | Management-system claims are frequently used in supplier filtering but can be outdated or misrepresented. | Certificate number and issuer can be cross-checked through recognized accreditation-backed channels before PO. | Certificate cannot be verified or does not match issuing certification body details. | IAF CertSearch information guide |
Standards Drift and Regulatory Timeline
Key version and legal-date changes are shown as decision inputs so teams can avoid outdated citation drift in RFQ and release packs.
Version-change decision table
| Signal | Verified update | Decision impact | Minimum action | Source |
|---|---|---|---|---|
| HSE guidance page updated | Public HSE magnetic-lifting page shows update date Oct 29, 2024 and still cites BS EN 13155:2003+A2:2009 in legal context. | Using HSE alone can leave teams with legacy edition references in RFQ/compliance text. | Do not copy standard edition blindly. Confirm active edition with standards body and project jurisdiction before release. | HSE magnetic lifting devices page |
| BSI EN 13155 listing drift | BSI catalog shows BS EN 13155:2020 (amended by A1:2025) and marks BS EN 13155:2003+A2:2009 as superseded/withdrawn. | Edition mismatch can invalidate technical submissions or trigger rework in audit/review. | Require supplier to declare edition + amendment in test reports, declaration files, and quote assumptions. | BSI standard listing page |
| BSI noted technical change | BSI listing notes reduction of number of load cycles for class HC1 from 20,000 to 16,000. | Lifecycle and duty assumptions can drift if teams continue using older cycle figures. | Ask supplier for duty-cycle basis tied to cited edition and include it in acceptance criteria. | BSI standard listing page |
| EU machinery legal switch | EUR-Lex Regulation (EU) 2023/1230 corrigendum sets application date at Jan 20, 2027. | Late-stage projects can fail legal-route alignment if transition timing is ignored. | Set a compliance date gate in project plan and avoid mixed Directive/Regulation claims after switch date. | EUR-Lex CELEX 32023R1230R(01) |

Known vs unknown matrix
| Item | Status | Reason | Action |
|---|---|---|---|
| Condition-based capacity sensitivity | Known | Public HSE and supplier content consistently shows surface/profile/contact dependence. | Keep derating factors explicit in tool output and RFQ package. |
| Rigging-angle high-risk threshold | Known | OSHA Safe Sling Use guidance provides practical warning threshold near 30° from horizontal. | Treat low-angle geometry as conditional gate before release. |
| Accreditation-based report authenticity checks | Known | ILAC guidance provides concrete pathways to validate reports and accreditation claims before relying on them. | Require supplier package to include verifiable accreditation route and scope for each critical report. |
| Cycle and temperature multiplier calibration in this checker | Partially known | Public guidance confirms direction of risk, but no harmonized open threshold curve matches all use cases. | Keep multipliers labeled as internal screening heuristics and require field validation. |
| Permanent-lifter FoS numeric baseline from open sources | Unknown | Current public source set used on this page does not provide a stable, directly citable numeric FoS baseline for all permanent manual lifters. | Pending confirmation: require model-specific breakaway and safety-factor evidence from supplier or licensed standard text. |
| Cross-brand universal loss curve for vertical handling | Unknown | No harmonized public dataset found with comparable test protocol. | Pending confirmation: require brand/model-specific pull-off and breakaway evidence from supplier. |
| Public failure-rate benchmark for 100 kg class by scenario | Unknown | No open-source benchmark with consistent causal labeling was found. | Pending confirmation: keep this page as decision-support screening, not predictive failure analytics. |
| Current EN 13155 edition mapping for each jurisdiction | Partially known | HSE legal context references 2003+A2:2009 while BSI listing shows 2020 lane and amendment updates; jurisdictional adoption still requires project confirmation. | Treat edition selection as a mandatory RFQ gate and validate with local compliance owner. |
| Unit-conversion misunderstanding in buyer communication | Partially known | Unit confusion is common in mixed-system procurement threads but impact varies by workflow. | Force explicit kg/lb fields in inquiry and quote templates for every deal. |
Option Comparison and Tradeoffs
Alternatives are evaluated in one frame so teams avoid choosing on list price or nominal class alone.
Comparison table
| Option | Best for | Reliability | Tradeoff |
|---|---|---|---|
| 100 kg permanent magnetic lifter | Stable ferrous loads with strong contact quality and routine handling | High when assumptions are aligned | Margin collapses quickly under thin stock, poor surface, or geometry drift. |
| 200 kg magnetic lifter (same workflow) | Workflows with variable surface quality or moderate uncertainty | Higher margin at same load profile | Higher cost and weight; may reduce handling convenience. |
| Electro-permanent architecture | Operations requiring controlled activation and broader adaptability | Potentially strong with proper controls | Adds system complexity, control dependencies, and integration cost. |
| Mechanical clamp / alternate gripping method | Boundary-critical scenarios (vertical, mixed material, high heat) | High when matched to load geometry | Longer setup and potential throughput penalty. |
| Lowest-price supplier with unverifiable evidence package | Only short-term quote comparison | Low for release decisions | Can save upfront cost but increases rework, audit failure, and deployment delay risk. |
Risk Translation and Mitigation
Risks are mapped by probability and impact with concrete mitigation actions.
Risk matrix
| Risk | Probability | Impact | Mitigation |
|---|---|---|---|
| Nominal 100 kg selected without condition evidence | High | High | Require representative pull-off / breakaway evidence before release. |
| Vertical-face path or low sling angle introduced after procurement | Medium | High | Keep route-specific review and block release when sling angle trends toward <30° without qualified approval. |
| Temperature drift beyond planned range | Medium | High | Set thermal gate in SOP and require updated checker run when exceeded. |
| Regulatory scope mismatch in compliance claims | Medium | High | Use applicability matrix and cite jurisdiction/equipment scope in RFQ and SOP documents. |
| Standard-edition drift between HSE references and current EN listing | Medium | High | Lock exact edition/amendment in quote and declaration package; reject generic “EN 13155 compliant” wording. |
| Material traceability incomplete | Medium | Medium | Collect material proof and conservative fallback method before purchase lock. |
| Inspection cadence degrades under production pressure | Medium | High | Bind inspection ownership and schedule to release gate, not post-launch cleanup. |
| Fake or unverifiable test/certification records | Medium | High | Validate accreditation/certificate routes before PO and reject packages without traceable evidence. |
Scenario Examples
Each scenario includes assumptions, outcome, and minimum next action.
Steel plate transfer in machining cell
- - Load 72 kg, thickness 22 mm, clean contact
- - Horizontal handling, 8 lifts/hour, sling angle 60°
- - Known ferrous material
Result: Checker typically returns Recommended with high confidence and 100 kg class fit.
Next action: Proceed with inquiry package including inspection cadence and proof-document request.
Low-angle rigging introduced during line balancing
- - Load 82 kg, thickness 18 mm, mixed geometry
- - Sling angle adjusted to 25° from horizontal
- - No written qualified-person approval
Result: Checker pushes case to Not recommended because low-angle rigging moves the scenario out of scope.
Next action: Redesign rigging route or escalate to qualified review before model lock.
Battery-fed powered magnet lane over 20 kg SWL
- - Site intends to use powered magnet architecture
- - No low-battery warning evidence in vendor documents
- - No standby-hold test records provided
Result: Decision remains Conditional until warning and hold controls are evidenced.
Next action: Require warning timing and standby-hold proof before procurement approval.
Supplier quote cites legacy EN 13155 edition only
- - RFQ package references BS EN 13155 without edition lock
- - Supplier declaration mentions 2003+A2:2009 only
- - Project sign-off requires current and auditable compliance trail
Result: Decision remains Conditional because standards-version mismatch can block release and audit acceptance.
Next action: Escalate standards mapping, lock edition/amendment in writing, and refresh test/declaration documents before PO.
Thin sheet + elevated heat + uncertain material batch
- - Load 90 kg, thickness 6-8 mm
- - Ambient around 120°C
- - Mixed materials and occasional vertical transition
Result: Not fit for quick 100 kg decision lane.
Next action: Use engineering-led alternative method and confirm standards/control package first.
Lowest quote arrives with logo-only certificates
- - Supplier package contains scanned certificates without clear issuing-body verification path
- - No accreditation scope or report traceability details are provided
- - Project timeline is tight and procurement pressure is high
Result: Decision remains Conditional because evidence authenticity is not established.
Next action: Run accreditation/certificate verification checks and request corrected evidence pack before PO.
FAQ: 100 kg Lifting Magnet Decisions
Questions are grouped by decision intent for quick execution.
Tool Inputs and Outputs
Why does the checker ask for thickness and geometry?
Because magnetic coupling depends on contact condition and shape. Nominal class without those inputs is misleading.
Can I use this checker if I only know load weight?
You can run a preliminary screen, but the output should be treated as conditional until contact/material data is added.
What does “assumption fit” mean?
It shows how close your case is to baseline conditions. Out-of-scope means the quick checker is not enough for release.
Why can the same load give different class outputs?
Because surface, orientation, temperature, and cycle intensity change effective demand in the model.
Is “100kg lifting magnet” different from “100 kg lifting magnet”?
No. This page treats them as equivalent buyer wording for the same 100 kg class screening intent.
Why did you add sling angle as an input?
OSHA safe-sling guidance flags <30° from horizontal as high-risk unless approved by manufacturer or a qualified person.
Boundaries, Safety, and Evidence
Is a Recommended output equivalent to compliance approval?
No. It is a screening result. Compliance and release still require documented controls and applicable standards checks.
Does HSE >20 kg warning logic apply to all magnetic lifters?
No. That trigger is for powered magnetic lifting systems in HSE guidance scope, not every permanent manual lifter.
Does the 10-minute warning mean “battery at 50%”?
Not as a fixed public rule in our cited source set. The controllable interpretation is warning before supply reaches release threshold for the held load.
When should I treat the output as not usable?
When vertical-face handling, low sling angle (<30°), high heat, unknown material, or near-limit utilization appears.
Why mention OSHA sling-angle guidance in a magnet page?
Because rigging geometry can invalidate an otherwise acceptable magnet selection and create high-risk force amplification.
Are cycle and temperature factors in the checker regulatory limits?
No. They are internal screening heuristics based on guidance direction, and should be validated against site evidence.
Why does this page mark permanent-magnet FoS numeric value as pending confirmation?
Because this stage uses only openly available sources in the page evidence map, and that source set does not give a stable universal FoS number for all permanent manual lifters.
How should I handle evidence gaps?
Mark them explicitly, keep result in conditional lane, and request supplier-specific proof before final purchase decision.
Procurement and Execution
What should be included in the inquiry after running the tool?
Include load range, contact/surface details, geometry, orientation, temperature, cycle profile, and required proof records.
Should I jump directly to 200 kg to be safe?
Not always. Higher class may improve margin but can add cost and handling drawbacks. Use comparison and risk tables first.
How do I avoid quote-level misunderstandings?
Force explicit kg/lb units and boundary assumptions in every quote and RFQ thread.
Which EN 13155 edition should appear in RFQ and supplier declarations?
Use an explicitly versioned reference agreed by your jurisdiction/compliance owner. Do not accept unversioned “EN 13155 compliant” claims.
Do I need to plan for EU machinery compliance date changes?
Yes for EU-bound projects: include a date gate around Jan 20, 2027 and keep declaration language aligned with the applicable legal instrument.
What is the fastest fallback if result is Not recommended?
Switch to an alternative gripping architecture and start engineering review instead of forcing a 100 kg-class purchase.
What if we cannot access full ASME standard text immediately?
Use this page only for pre-screening and mark release as pending until licensed standard clauses are mapped to controls.
How can I quickly verify whether supplier test reports are trustworthy?
Use accreditation-backed verification routes (for example ILAC signatory pathways) and reject reports that cannot be tied to a verifiable scope and traceability chain.
Is an ISO 9001 certificate enough to approve a 100kg lifting magnet supplier?
No. Management-system certification does not replace product-specific test evidence, application-fit data, and release-control documentation.
What extra check is mandatory for second-hand magnetic lifting equipment?
Request the latest thorough-examination details and confirm suitability for the intended application before accepting the quote.
