Область применения
This standard applies to underground load-haul-dump (LHD) machines used in metal and non-metal underground mines, underground engineering, and tunnels. It covers diesel LHDs, electric LHDs, and remote control LHDs. It is mandatory for manufacturers of underground mining machinery targeting the Chinese market. The standard does not cover general mechanical, electrical, hydraulic, or pneumatic hazards that are addressed in GB/T 15706.1 and GB/T 15706.2.
Технические требования
The standard specifies comprehensive safety requirements and protective measures for underground LHDs across their entire lifecycle. It mandates risk assessment for various hazards, including mechanical, electrical, thermal, and noise-related risks. Manufacturers must implement design measures to mitigate these risks and ensure operator safety. Key areas include hydraulic systems, where pressure relief valves and hose shielding are required, and electrical equipment, which must comply with specific insulation and grounding standards. For braking systems, the standard outlines performance criteria for service, secondary, and parking brakes, ensuring the vehicle can stop safely under various load and gradient conditions. The braking system must be designed to prevent unintended movement and provide reliable deceleration. Control systems must meet category 1 requirements as defined in GB/T 16855.1, and emergency stop devices must be easily accessible. The standard also details requirements for operator cabins, including the installation of Falling Object Protective Structures (FOPS) and Roll-Over Protective Structures (ROPS) compliant with GB/T 17771 and GB/T 17922. Cabins must provide adequate visibility, emergency exits, and fire-resistant materials. Additionally, it specifies limits for noise and vibration exposure, lighting requirements, and the mandatory inclusion of fire extinguishers.
Методы испытаний
- Braking Performance Test: Evaluates the stopping distance and deceleration capabilities of service and secondary brakes according to GB/T 21152. - Exhaust Emission Measurement: Assesses the concentration of harmful gases like CO and NOx from diesel engines. - Noise Level Measurement: Determines the noise exposure limits at the operator's ear position. - Vibration Assessment: Measures whole-body vibration exposure limits in accordance with GB/T 13441.1.
Частые вопросы
What types of underground LHDs are covered by GB 25518-2010?
The standard covers diesel, electric, and remote control underground load-haul-dump machines used in metal and non-metal underground mines, tunnels, and underground engineering projects.
Are protective structures mandatory for the operator cabin?
Yes, the standard requires the installation of either Falling Object Protective Structures (FOPS) or Roll-Over Protective Structures (ROPS) to protect the operator from falling objects and rollover incidents.
Does GB 25518-2010 specify requirements for fire safety?
Yes, underground LHDs must be equipped with portable ABC dry powder fire extinguishers, and the cabin materials must be fire-resistant.
