The electric hoist can be installed on the I-beam rail under the main beam of the single girder crane and run left and right as the lifting mechanism of the single girder crane, so the single girder crane can also be called the electric hoist single girder crane. The single beam crane has been used for a long time, and the electric hoist may have some problems, such as failure to descend normally. What should we do at this time? I would like to share the reasons why the electric hoist can not fall normally and the solutions.
The failure of the electric hoist to descend normally poses a great threat to the operators and will also cause economic losses to everyone. Let’s see what causes the electric hoist to fail to descend.
1) The brake pads are too tight
First of all, after wear and use, the brake pads will only become looser and looser, and will never become tighter and tighter. It is possible that after maintenance and adjustment of the brake pads, we directly carried out the operation without testing. The distance between brake pads is abnormal.
2) Fatigue operation of internal parts of electric hoist
The internal parts are heated during continuous operation. Affected by other parts, other parts may fail.
3) Transmission parts of electric hoist are blocked
It is also possible that there is a big problem with the transmission part of the electric hoist itself, which is directly stuck there when descending.
4) The electric hoist is operated at high temperatures or high load
High load operation of electric hoist will make the brake pads loosen and tighten with high strength. Fatigue of the brake pads may lead to direct locking of the electric hoist.
Electric hoist single beam crane is a low working level lifting equipment. If the working intensity is too high, it may have a certain impact on the life of the hoist and speed up the damage of the equipment. When the electric hoist fails to descend normally, first find out the cause of the problem, and then formulate solutions according to the cause.
- Adjusting brake pads
- Reduce work intensity
- Repair the transmission parts of the electric hoist
It is common for mechanical equipment to fail. If maintenance can be done well during normal use, the probability of equipment failure can be greatly reduced.
