Increase the safety brake
The safety brakes to be added here refer to the brake settings of the vertical shiplift, the addition of the brake discs in the reel and the array of disc brakes in the appropriate position to make them a fully independent set of safety brakes system. The advantage of doing so is obvious.
(1) the liberation of the manpower operation of the guardians, to reduce the risk of injury;
(2) to enhance the safety and reliability of the crane operation, when the crane accident can effectively prevent the expansion of the accident. If the crane, the drive shaft, the working brake, and the gear box are damaged, the safety brake of the reel part can effectively close the brake and stop the crane. Hooks continue to decline to prevent further expansion of the accident;
(3) In some special bridge cranes that need to be mechanically switched from gearboxes, simply press the safety brakes to ensure that the reel is tightened by the safety brakes and do the appropriate safety precautions Misoperation measures, you can as needed, release the working brake for high-speed and low-speed file exchange work.
