Escopo e aplicabilidade

GB 21500-2008 applies to diesel trackless tyred mining trucks used in underground metal and non-metal mines, engineering projects, and tunnels. It establishes safety requirements based on physical performance and intended use throughout the machine's lifecycle. This standard is mandatory for all manufacturers of underground mining trucks. It does not cover hazards addressed in GB/T 15706.1-2007 and GB/T 15706.2-2007.

Requisitos técnicos

The standard specifies comprehensive safety requirements across multiple systems. For mechanical safety, it mandates protective devices for rotating parts, secure high-pressure fluid lines, and articulation lock devices. The engine and fuel system must use low-pollution diesel engines, with steel fuel tanks capable of withstanding specific pressure tests and fire-resistant routing for all fluid lines in the engine compartment. For hydraulic and electrical systems, the standard requires pressure safety valves, protective shielding for high-pressure hoses near the operator, and proper electrical circuit protection. The braking system must include service, secondary, and parking brakes, with specific performance criteria for deceleration and reaction times. Operators must ensure braking force meets at least 40% of the vehicle's maximum weight for service brakes. The standard also defines environmental and operational limits. It sets maximum noise levels at the driver's position and establishes concentration limits for harmful gases like CO and NO2 in the workplace. Lighting and visibility requirements mandate specific illumination levels in transport tunnels and loading areas, along with ROPS and FOPS structures to protect the operator.

Métodos de ensaio

Testing methods referenced include performance tests for braking systems per JG/T 48, and laboratory tests for ROPS and FOPS structures according to GB/T 17922 and GB/T 17771. The standard also references procedures for evaluating noise and vibration levels at the operator's position.
