Construction Hoist Safety Device
Safety is one of the most important for Construction Hoist, thus the Construction Hoist Safety Device is required. SAJ safety device is a product of BQ. When a cage over-speeds the device should act cut off the power stop the cage on mast gradually. The safety device is adjusted and sealed. Do not disassemble it. The using time limit of safety device are signed on it`s nameplate. Safety device must be delivered to the factory and inspected after it reached to time limit.
Safety device board is the connected part between safety device and other structures, it can take the impact of stopping the cage. There are installed lower speed switch, upper travel limit switch and final limit switch, once the switchs touch the relevant cam the cage will act.
We also supply other spare parts for construction hoist, such as construction hoist Mast Section, Construction Hoist Anchorage Frame, Passenger Hoist Cage, Construction Hoist Overload Protector, Sliding Contact Line, Construction Hoist Motor, Construction Hoist Reducer and so on.
