The importance of "duty safety" of group hoist

Group crane electric hoist is a new type of electric hoist developed in recent years. The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device. Its disadvantages are: large length dimension, large width dimension, rough structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low-voltage control, which increases the safety of the control system. Due to its lightness and convenience, it is gradually replacing some electric hoists.

The electrical control department adopts low-voltage control, which increases the safety of the control system. It is a high-quality, high-performance product. Although its quality has been strictly handled in production, we still need to be cautious in daily use and must be checked. safe job.

1. Before starting the group hoist, check whether the hooks, slings, and electrical equipment are abnormal. After finding abnormalities, start the operation again for 1-2 minutes..

2. Check whether the handle button or remote control is up and down, whether the left and right directions are accurate and sensitive, and whether the motor and reducer make abnormal sounds.

3. Check whether the chain is kinked, broken, deformed, etc., and whether the chain is adjusted or replaced in time.

4. Check whether the brake is normal, and check whether the joints, hooks, hooks, etc. are normal. abnormal.

These are necessary checks before starting, and they are also very important. Of course, if there is a safety problem during the operation, the operator should stop and check in time to ensure safety. If you have any questions, please feel free to contact us. We are happy to help you.
