GB/T 45874-2025 in English

Analysis of the core safety requirements of the standard

Key points of mechanical hazard protection

The standard puts forward specific protection requirements for 7 major types of mechanical hazards:

• Tipping protection: no-load roll angle ≥20°, steering axle load accounts for 18-20%
• Moving parts protection: rotating parts isolation distance ≥100mm
• High temperature surface protection: hydraulic pipelines ≥60℃ require insulation layer

Special requirements for electric equipment

Standard implementation recommendations

1. FMEA failure mode analysis must be completed during the design phase
2. Focus on monitoring hydraulic pipeline sealing tests during production
3. Dynamic braking performance tests must be performed before shipment

Technology evolution analysis

Compared with the 2010 version of the standard, the 2025 version adds the following:

• Electric equipment charging interlock requirements (5.13.2)
• Applicable clauses for autonomous cleaning robots
• High-pressure water system safety valve setting standards
