Champ d’application

This standard applies to underground mine track wheel loading machines, including bucket loaders, scraper loaders, vertical claw loaders, crab claw loaders, and backhoe loaders. It specifies the safety requirements and protective measures for these machines throughout their lifecycle. It is mandatory for manufacturers targeting the Chinese mining equipment market, excluding general mechanical and electrical hazards covered by GB/T 15706.1.

Exigences techniques

The standard outlines comprehensive safety requirements for the physical properties and intended use of the machinery. It mandates that machines must be designed according to ergonomic principles, ensuring sufficient strength, stiffness, and stability. Manufacturers must adhere to specific track gauges and ensure reliable fastening and protective measures against mechanical hazards. Specific requirements are established for protective devices, notably mandating Falling Object Protective Structures (FOPS) for certain loader types. The standard also details stringent criteria for pneumatic and hydraulic systems, including pressure relief mechanisms and protective shielding for high-pressure hoses located near operators. Electrical and lighting systems must comply with explosion-proof regulations where applicable, ensuring safe operation in hazardous environments. Furthermore, the standard specifies requirements for operator workstations, control layouts, and emergency stop mechanisms, referencing GB 16754 for emergency stop design principles. Machine stability must be verified through calculation and testing across all lifecycle phases.

Méthodes d’essai

The standard references various evaluation procedures to verify compliance, including laboratory evaluations for operator seat vibration and tests for Falling Object Protective Structures (FOPS). It also requires verification of machine stability through both calculation and physical testing. Additionally, compliance with noise limits and the operational forces of control devices must be assessed according to referenced national standards.
