Inspections Required After Initial Installation of an Electric Chain Hoist

After initial installation, every electric hoist should be run idle several times to check for any abnormalities. This is crucial for safe operation. So, what inspections should be performed after initial installation of an electric chain hoist?

Before using an electric chain hoist, a dynamic load test at 10% of the rated load should be conducted, repeatedly raising and lowering the hoist to check whether the transmission mechanism, electrical components, and connections are functioning properly. A static load test at 25% of the rated load should be conducted, lifting the load approximately 10 cm off the ground, stopping for 10 minutes, and removing the load to check whether all components are functioning properly.

When using an electric chain hoist, it is strictly forbidden to overload the hoist, lift loads at an angle, or drag the hoist horizontally. The limiter is an emergency device designed to prevent the hook from failing to stop during the raising and lowering process. It is primarily used to prevent the hook from damaging the hoist. Therefore, the limiter should not be used as a switch.

After using the electric chain hoist, the main power supply should be disconnected immediately. Operators of the electric chain hoist should also be familiar with the product's operating instructions, precautions, and operating principles.

These are the necessary inspections for the initial installation of the electric chain hoist. If you have any further questions, please contact our staff.
