If the car is hoisted when the electric hoist is hoisted or the operation method is improper, it will cause the electric hoist to swing the hoist and cause a dangerous accident. When the hoist of the group hoist electric hoist rises, it should be stopped when it is tightened by a steel wire rope or a chain. The group hoist electric hoist will find the hook again according to the jittering position of the hook, and the lifting worker should check whether the hoist is hanging; When the electric hoist of the group hoist lifts an object, the speed should not exceed the block, and the lifting object can properly speed up the lifting speed when leaving the obstacle; the lifting hoist of the electric hoist is not easy to be too high.
When the group hoist electric hoist works when the object is hoisted. When conditions permit, it is better to hang about 0.5m above the ground, and the lifting workers should stabilize the objects behind the electric hoist hanging objects, and run around the obstacles under the command of the lifting workers. The group hoist electric hoist should be careful not to be intermittent when working. If you need to run for a long distance, it is best to use long-term power transmission operation. The group hoist electric hoist should ensure that the hanging object is stable when working. If the group hoist electric hoist swings or shakes, the hook should be stabilized while running, and the object should not be allowed to swing arbitrarily. When it is found that the fault of the group hoist electric hoist is also normal, and the equipment has a service life, when the problem occurs, we first think that it should be solved. In some cases, the voltage of the group hoist motor is normal, but the group hoist electric hoist does not work, so think about other reasons, such as: the motor needs to be replaced during maintenance. The chain hoist electric hoist has not been used for a long time and other reasons have caused the brake wheel and the end cover to rust, the brake wheel cannot be disengaged when starting, the motor only emits a "hum" sound, and cannot rotate to cause it to fail to work. At this time, the brake wheel should be removed, and the rusty surface should be cleaned, and then re-commissioning; when the motor is heavily bored, the motor will not rotate. Once this occurs, it should be stopped. At this time, the motor must be overhauled or replaced. Ensure that the group hoist electric hoist works normally.
