- Preparation stage
Inspect the appearance of the chain hoist to confirm that the chain is not twisted or damaged, and the hook is firm and not deformed.
Ensure that there are no obstacles in the working area and that the surrounding personnel are at a safe distance.
Connect the power supply and check whether the electrical system is normal.
- Hanging the heavy object
Securely attach the hook to the appropriate position of the heavy object to ensure a firm and reliable connection.
- Start ascending
The operator presses the ascending button, the motor starts to run, and the chain is driven by the sprocket to make the heavy object rise slowly.
- Lifting and moving
Control the chain hoist to move the heavy object horizontally along the predetermined track or direction to ensure smooth and stable movement without shaking.
- Precise positioning
When reaching above the target position, fine-tune the ascending or descending operation to make the heavy object reach the specified position accurately.
- Slow descent
Press the descent button and slowly lower the heavy object until it is placed stably on the supporting surface.
- Shutdown operation
After the work is completed, release the operation button and turn off the power supply.
- Inspection and maintenance
Inspect the chain hoist, including the lubrication of the chain and the connection of electrical components, to prepare for the next use.
For example, when handling goods in a warehouse, a chain hoist is used to lift boxes of goods, move them to the designated shelf position, and then place them accurately. The entire process follows the above working process to ensure the safety and efficiency of the handling work.
