EXECUTIVE SUMMARY
Scope: 通用桥式起重机 (General-purpose overhead travelling cranes) — product-standard comparison only. Both GB/T 14405-2011 and EN 15011:2020 are TIER 1 product standards; equivalence is MOD (not IDT) — EN 15011 is a C-type machinery-safety standard delegating structural design to EN 13001, while GB/T 14405 embeds requirements directly and relies on GB/T 3811. Key implication: a GB/T 14405 crane is not CE-presumptive — structural/load-case re-verification to EN 13001 is required before EU placement.

STANDARD TIER CLASSIFICATION
| Standard | Tier | Description |
|---|---|---|
| GB/T 14405-2011 | TIER 1 — Product Standard | Crane types, dimensions, performance, inspection |
| EN 15011:2020 | TIER 1 — Product Standard | Safety/performance requirements, bridge & gantry cranes |
| GB/T 3811-2008 | TIER 2 — Design Method | Loads, load combinations, duty classification |
| EN 13001-1/-2/-3-1 | TIER 2 — Design Method | General design / load actions / limit states |
| GB 6067.1-2010 | TIER 3 — Safety Code | Mandatory safety rules |
| GB 50278-2010 | TIER 3 — Installation/Acceptance Code | On-site installation verification |
FLAG: GB/T 14405-2011 is cited for structural/mechanism performance — valid, as it incorporates GB/T 3811 by reference; EN 15011 delegates the same to EN 13001. Comparison must therefore be made at the GB/T 3811 ↔ EN 13001 layer for structural items.

KEY DIFFERENCES SUMMARY
- Structural design method — allowable stress (GB/T 3811) vs limit-state partial factors (EN 13001-3-1): different method, no direct comparison → 不可互认 (Not mutually recognised) → HIGH.
- Load combinations — GB/T 3811 §4 vs EN 13001-2: different rules → 不可互认 (Not mutually recognised) → HIGH.
- Duty classification — A1–A8 (GB/T 3811 §3) vs EN 13001-1/ISO 4301-1 groups: different basis → 附加测试后互认 (Mutual recognition after additional testing) → HIGH.
- Electrical/controls — GB 5226.1 vs EN 60204-32: aligned in principle → 附加测试后互认 → MEDIUM.
- Capacity/span series — tabulated only in GB/T 14405 → 附加测试后互认 → LOW.

AUDIT FLAG RESOLUTION
- ✅ RESOLVED: GB/T 14405-2011 status = CURRENT (现行) per official authority — no supersession note applied.
- ✅ FALSE POSITIVE (domain flag): GB/T 14405-2011 cited for structural performance — valid; it incorporates GB/T 3811-2008 by reference (TIER 2 extension legitimate).
- ⚠️ UNRESOLVED: Exact capacity/span series and clause numbers — verify against GB/T 14405-2011 §4.
- ⚠️ UNRESOLVED: EN 15011:2020 amendment status — verify CEN catalogue.
- 🔴 CRITICAL CORRECTION: Neither draft may assert IDT equivalence — structural method divergence (allowable stress vs limit state) precludes it; recorded as MOD.
PROCUREMENT VERDICT
- Treat GB/T 14405 crane as MOD, not IDT — budget EN 13001 structural re-verification for EU/CE use.
- Obtain GB/T 3811-2008 load-case calculations from supplier; map to EN 13001-2 combinations.
- Confirm duty class mapping (A-class ↔ ISO group) in writing.
- Verify GB 6067.1-2010 safety-device compliance and TSG manufacturing licence.
- Require EN 60204-32 electrical conformity for EU destination.
- Specify GB 50278-2010 acceptance records for installation.
