How does workshop overhead crane work?
The travelling of workshop overhead crane is composed of three movements, vertical crane travelling, horizontal trolley crane, up and down lifting movement.
First is the transmission of lifting mechanism. The power resource of lifting mechanism is from electric motor, then the power is passed to reducer’s high speed shaft end through gear coupling, compensation shaft, brake wheel shaft coupling, it turns motor’s high revolution to the needed revolution through reducer, then transmitting through reducer’s low speed shaft, through drum’s annular gear, transporting the power to drum group, up and down through wire rope and trolley group, then finishing loading and unloading material.
Second is the transmission of trolley travelling device. Power from electric motor through brake wheel shaft coupling, compensation shaft, semi gear coupling, transports to high speed shaft end of vertical three-grade reducer, then turning motor’s high revolution to the suitable revolution through reducer, transporting through low-speed shaft of reducer. Then through semi gear coupling, compensation shaft, the connection between semi gear coupling and trolley driving wheel, it drives the trolley driving wheel to run, and transporting the material in horizontal direction.
Third is crane travelling device. Power form motor transports to reducer’s high speed shaft end through brake wheel coupling, compensation shaft, semi gear coupling, turns motor’s high revolution to suitable revolution through reducer, and transmits through reducer, and connects with crane driving wheel through whole gear coupling, and drives the crane driving wheel run and lifts the material in vertical direction. The driving mechanisms on the ends of crane are the same.
Daily safety checkout of crane hooks
Check that there’s no more that 10 percent wear on any part of the hook.
Check for bending or twisting and cracks.
Check that safety latches are in place and functioning properly.
Ensure that the hook nut (if visible) is tight and locked to hook.
Make sure that the hook rotates freely without grinding.
