Introduction
Analysis of the core content of the standard
| Technical modules | Key requirements | Innovation points |
|---|---|---|
| Preparation before loading | Personnel must be certified, the bearing capacity of the vehicle's securing points must be ≥20kN, and the cargo gap must be ≤300mm | The quantitative standard for unstable cargo is clarified for the first time (L/H≤0.8, B/H≤0.7) |
| Reinforcement technology | Top bolting angle ≥30°, corner bolting ≤45°, pre-tightening force standard 4kN | The concept of combined bolting is introduced, allowing the coordinated use of blocking limit and friction bolting |
| Dynamic inspection | The first inspection shall be carried out after 100km of transportation, and then every 4 hours/time, and after emergency braking | Establish a digital inspection record template (Appendix G) |
Key technical parameters
Measurement method of dynamic friction coefficient
The standard innovatively proposes a slope test method: slowly tilt the patterned steel plate cargo box from a horizontal state, and record the tilt angle when the cargo starts to slide. The tangent value is the μ value. μ value range for common material combinations:
- Wood - Patterned steel plate: 0.30-0.60
- Flat steel plate - Corrugated cardboard: 0.20-0.40
- Plastic - PVC: 0.15-0.50
Typical application scenarios
Metal sheet coil transportation case
Special supports must be used when transporting steel sheet coils, with an inclination angle of 37° and a ground clearance of ≥20mm. When using wedge-shaped supports:
- Each support must withstand ≥1.5 times the weight of the cargo
- The longitudinal spacing shall not exceed 1.5 times the diameter of the coil
- When used with the chain lashing assembly, edge guards must be installed at the contact point between the chain and the coil
Analysis of Standard Evolution
Compared with EU EN12195-1:2010, this standard has three major breakthroughs:
- Refine the determination of unstable cargo: Add quantitative indicators of length-to-height ratio and width-to-height ratio
- Strengthen process control: Require the loading plan to include mid-haul loading and unloading plans
- Innovate the inspection mechanism: The first re-inspection system after a 500-1000m trial run
Implementation recommendations
Corporate response strategies
| Phase | Action points |
|---|---|
| Preparation period | Configure new blocking devices such as air bags and intermediate blocking rods, and update the labeling system of the fastening devices |
| Implementation period | Establish an electronic loading plan database and compulsorily install on-board inspection and recording terminals |
| Supervision period | Use AI image recognition technology to automatically detect cargo displacement trends |
