The 3 phase electric chain hoist is a small lifting equipment with the advantages of compact structure, light weight, small size, strong parts versatility, and easy operation. It can be installed on hoist single beam, bridge crane, gantry crane, and jib crane. With slight modifications, it can also be used as a hoist. Therefore, it is one of the heavy equipment commonly used in factories, mines, ports, warehouses, freight yards, stores, etc. It is an essential machine to improve labor efficiency and improve working conditions.
Precautions for using electric hoist
1. When installing or reassembling the 3 phase electric chain hoist manufacturer for the first time, the wire rope electric hoist should be operated without load first, but make sure that the components are installed properly and do not energize.
2. Before normal use, a static load test should be carried out at 125% of the rated load, lifted about 100 mm from the ground, for 10 minutes, and checked to see if it is normal.
3. The dynamic load test is a repeated lifting and left-right movement test based on the rated load weight. After the test, check whether the mechanical transmission part, electrical part and connecting part are normal and reliable.
4. It is not allowed to press two flashlight door buttons at the same time to make the sevencrane 3 phase electric chain hoist factory move in opposite directions.
5. After the work is completed, the main switch of the power supply must be opened and the power supply must be cut off.
6. The electric hoist should be operated by a dedicated person, and the operator should fully understand the safe operating procedures. It is strictly forbidden to pull or lift at an angle.
7. During use, specialized personnel must regularly inspect the electric hoist, take timely measures if any faults are found, and record them carefully.

9. When oiling the wire rope, you should use a hard brush or small wooden piece. It is strictly forbidden to oil the working wire rope directly with your hands.
10. When the wireless remote control 3 phase electric chain hoist company is not working, no heavy objects are allowed to be suspended in the air to prevent permanent deformation of the parts.
11. During use, if a fault is found, the main power supply should be cut off immediately.
12. A 10 to 20 ton hoist may automatically power off after a long period of continuous operation. This is the overheating protection function of the motor. It can be lowered at this time. After a period of time, the motor can continue to work after it cools down.
