Why can't the climbing frame electric hoist be improved?

When the climbing frame electric hoist cannot be lifted synchronously, the main reason is that the hoist motor is different. Since the climbing frame electric chain hoist uses a three-phase disc brake motor as its power, the rotation speed of different motors will have a difference in rotation speed, which causes the lifting to be unable to synchronize. Especially with the long running time of the whole group hoist, the speed difference will be larger, and the actual bearing capacity of each climbing frame electric hoist will change. The problem principle is as follows. (1) When the equipment is raised to the overall lifting at the beginning of the construction, it is necessary to stop and use the construction experience to feel the tightness of each climbing frame electric hoist chain by hand, and adjust the lifting or lowering of the loose or tight single climbing frame hoist. After the tightness of the chain is basically the same, it can be officially started up.
(2) The slow lifting load of some electric hoist with climbing frame is continuously reduced, or even no load. However, some electric climbing frame hoists have an increasing load due to their fast rise, and the possibility of overloading of the climbing frame hoist is increasing. In this case, if you do not pay attention to it, individual climbing frame hoists may be overloaded. (3) Climbing frame electric hoist is the work of multiple electric hoists to jointly lift the same item, which requires synchronous operation. The speed difference plays a decisive role in synchronous operation. (4) During the normal lifting operation, pay attention to the operation of the electric hoist, observe whether the electric hoist is stopped and the tightness of the chain, use your ears to monitor the operation of the motor and hoist for abnormal noises, and if an abnormal situation occurs, stop it in time. Find out the cause and adjust the tightness of the chain. The electric hoist that fails should be replaced and repaired in time.
