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.

The slag removal machine is one of the main auxiliaries of the boiler, and its operation status has a direct influence on the normal and continuous operation of the boiler. When the deslagging machine stops operating due to a fault, coal cinder generated from coal combustion cannot be discharged in time, which will cause serious accumulation of coal cinder at the tail end of the boiler grate, and eventually forced to stop operation. It can be seen that the normal operation of the slag removal machine is a prerequisite for the continuous operation of the boiler. Because the type III coal currently used for the 6t boiler is different from the type II coal that is suitable for the boiler design, resulting in a large amount of coal slag and serious slagging of the slag, together with some fatal defects of the “I†type slag remover. The slag removal machine has a high failure rate, which affects the normal operation of the boiler. Through the transformation of the structure of the boiler slag removal machine, the horizontal section of the machine body has been added, the rotating chain has been replaced and extended, the effective size of the screed plate has been increased, the position of the slag hole has been changed, and the guide roller and guide roller have been added. Changing the power transmission mode and supplementing it with other management measures will greatly reduce the failure rate of the slag removal machine, thus ensuring the normal and continuous operation of the boiler.
