Escopo e aplicabilidade

This standard specifies the safety requirements for track-type loading machines used in underground mines. It is applicable to underground mining products utilizing crawler walking mechanisms, including bucket rock loaders, vertical claw loaders, excavating loaders, and crab claw loaders. It is mandatory for manufacturers producing these specific types of underground mining equipment for the Chinese market. The standard addresses hazards during the entire lifespan of the equipment, excluding general mechanical, electrical, hydraulic, and pneumatic hazards covered by GB/T 15706.1 and GB/T 15706.2.

Requisitos técnicos

The standard outlines comprehensive safety measures based on a hazard identification table. Manufacturers must conduct risk assessments for each identified hazard. General requirements include ergonomic design, secure fastening of components, and reliable start/stop devices. For specific models like vertical claw, excavating, and crab claw loaders, the installation of Falling Object Protective Structures (FOPS) is required, complying with GB/T 17771. Protective guards must be installed for all rotating and moving transmission parts. Operational controls must be positioned safely and ergonomically, with critical controls featuring protection against accidental activation. The standard mandates specific braking system performance; for instance, parking brakes must hold the machine on a 15% slope when fully loaded and a 20% slope when empty, adhering to GB/T 19929. Pneumatic and hydraulic systems must include pressure release devices and safety valves, with specific shielding requirements for high-pressure hoses near operator stations. Electrical systems must meet general safety and explosion-proof requirements (referencing GB 3836.1 and GB 3836.2) for use in hazardous environments. For diesel-powered loaders, exhaust systems must include purifiers and silencers, with strict limits on harmful gas emissions (CO and NOx), and must be equipped with fire extinguishing devices.

Métodos de ensaio

The standard references various testing and evaluation procedures to verify compliance. Key testing areas include the laboratory evaluation of operator seat vibration (GB/T 8419), performance testing of braking systems for crawler machines (GB/T 19929), and laboratory tests for falling object protective structures (GB/T 17771). Additionally, diesel engine emissions are evaluated against specific concentration limits for CO and NOx to ensure safe air quality in underground environments.
