Escopo e aplicabilidade

This standard specifies the safety technical requirements for the design, manufacture, installation, and use of builder's hoists (construction lifts). It applies to both rack and pinion and wire rope type construction hoists as defined in GB/T 10054-2005. It is mandatory for all manufacturers and operators involved in the construction hoist industry in China.

Requisitos técnicos

The standard comprehensively regulates the structural integrity and safety mechanisms of construction hoists. It mandates specific requirements for the foundation, ensuring it can withstand maximum loads under adverse conditions, and sets strict dimensional limits for protective enclosures and landing doors to prevent accidental access. For the cage (car), the standard dictates minimum dimensions, emergency exit specifications, and load-bearing capacities for the floor and roof. It also mandates permanent electrical lighting and emergency lighting systems. Manufacturers must ensure cages are equipped with mechanical locking devices and electrical safety switches to prevent operation when doors are open. The standard details stringent criteria for wire ropes and pulleys, including minimum safety factors and diameter-to-rope ratios for various applications (e.g., lifting, counterweights, safety devices). It also specifies requirements for transmission systems, distinguishing between rack-and-pinion and wire rope drives, and mandates normally closed brakes with specific torque capacities. Critical safety features are addressed, including anti-fall safety devices, which must be progressive for certain hoist types, and various safety switches (limit, ultimate, slack rope). The standard also requires overload protection devices and specifies electrical system requirements, including insulation resistance, grounding, and protection grades (IP ratings) for different components.

Métodos de ensaio

The standard references testing and inspection procedures primarily outlined in GB/T 10054-2005. Key evaluations include structural load tests for the cage and mast, verification of verticality deviations for the mast, and functional tests for braking systems and anti-fall safety devices. It also requires inspection of electrical safety mechanisms, including limit switches and overload protection.
