What to do if the electric hoist of a single beam crane cannot be lowered

The electric hoist can be installed on the I-beam track under the main beam of the single-beam crane to run left and right, as the lifting mechanism of the single-beam crane, so the single-beam crane can also be called the electric hoist single-beam crane. The single-girder crane has been used for a long time, and the electric hoist may have some problems, such as not being able to descend normally. What should I do at this time? The editor will share with you the reasons and solutions for the failure of the electric hoist to drop normally.

Single-beam crane electric hoist should be maintained well

The failure of the electric hoist to descend normally poses a great threat to the operators and also causes economic losses to everyone. Then we have to look at what causes the electric hoist to fail to drop?

1) The brake pads are too tight

First of all, the brake pads will only become looser after wear and use, and will never appear to become tighter and tighter. It may be that we performed the work directly after maintaining and adjusting the brake pads without testing. Cause the distance between the brake pads to be abnormal.

2) Fatigue operation of internal parts of electric hoist

The internal parts are constantly running and heated. Affected by other parts, it may cause other parts to malfunction.

3) The transmission parts of the electric hoist are obstructed

It is also possible that the transmission part of the electric hoist itself has a big problem, and it is directly stuck there when it is lowered.

4) The temperature of the electric hoist is too high or high-load operation

The high-load operation of the electric hoist will make the brake pads loose and tighten with high intensity. If the brake pads become fatigued, the electric hoist may lock directly.

Electric hoist single-girder cranes belong to low-level lifting equipment. If the working intensity is too high, it may affect the life of the hoist to a certain extent and accelerate the damage of the equipment. When there is a problem that the electric hoist cannot be lowered normally, first find out the cause of the problem, and then formulate a solution based on the cause.

1. Adjust the brake pads

2. Reduce work intensity

3. Repair the transmission parts of the electric hoist

Mechanical equipment failure is a common occurrence. If maintenance work can be done in the process of normal use, the probability of equipment failure can be greatly reduced.
