Escopo e aplicabilidade

This standard applies to mechanical mining shovels used in open-pit mines and engineering projects, specifically those defined in GB/T 10604-2008. It addresses safety requirements and risk reduction during the machine's lifecycle. Manufacturers must ensure compliance to mitigate physical and operational hazards.

Requisitos técnicos

The standard outlines comprehensive safety measures addressing various hazards identified in the risk assessment. It specifies requirements for the operator's cab, including ergonomic design, visibility, and environmental controls such as temperature regulation and air filtration. Manufacturers must design cabs using flame-retardant materials to ensure operator safety. The standard also mandates specific dimensions and vibration limits for seating, referencing GB/T 8419 for testing. Control systems and devices must meet Category 1 requirements as defined in GB/T 16855.1-2008. The standard details the necessity of emergency stop devices, control layouts, and maximum operating forces for various control types. It is mandatory to install devices preventing unauthorized startup and ensuring safe shutdown during emergencies. The document sets forth requirements for pneumatic control and lubrication systems, emphasizing pressure safety valves and hose routing to prevent hazards. Electrical equipment must comply with GB 5226.1, including specific provisions for cables, cable reels, and residual current protection devices. Proper grounding and insulation are critical to prevent electrical hazards. Additionally, the standard covers braking systems, crowd and hoist mechanisms, platforms, and fire protection systems. It mandates the installation of portable fire extinguishers in critical areas and specifies environmental limits for dust, noise, and vibration. Compliance with these operational environment limits is essential for worker safety.

Métodos de ensaio

- Vibration Testing: Evaluation of seat vibration using methods specified in GB/T 8419. - Noise Measurement: Determination of noise at the operator's position under static and dynamic conditions per GB/T 16710.3 and GB/T 16710.5. - Dust Concentration Measurement: Assessment of dust levels in the operator's cab according to GB/T 5748. - Electrical Insulation Testing: Verification of main circuit insulation resistance as per GB 50150.
