Safety inspection before use of stage electric hoist: operational inspection
When testing the operation of the gourd, it is very important to test the upper and lower limits. The stage electric hoist limit device can prevent damage to the hoist, prevent the hook seat from entering the hoist, and prevent the chain from coming out of the hoist.
You should perform this test during the pre run check. If you are testing a double speed hoist, you should test the limit switch at two speeds.
Before testing, you should follow some safety precautions
1. Ensure that there are no obstacles in the area below the gourd or crane. Also, check if there is anyone underneath or in the path of the gourd, including yourself.
2. Ensure that there is no load on the gourd.
3. Prepare to stop the hoist operation through the emergency stop button.
Afterwards, please follow the following steps to measure the upper and lower limits:
1. Control the hoist hook to run upwards when there is no load on the hoist.
2. Is there any abnormal noise during the operation of the gourd.
3. The limit switch should stop the hoist before the hook seat hits it. If it cannot run, or if you think it will fail, please do not hit the bottom of the gourd. This may damage the gourd.
4. If the limit switch malfunctions, do not use this hoist again;
5. Next, control the hoist hook to run downwards and test the operation of the lower limit switch.
6. Follow the same steps as when testing the upper limit switch. During the process of lowering the hook, listen for any abnormal sounds.
7. Check for defects in the chain or wire rope.
8. Similarly, if the limit switch malfunctions, please deactivate the hoist.
Testing the upper and lower limits of your gourd is an important part of checking before operating it. If you have any questions or believe there is a problem with the function of the limit switch on your gourd at any time, please stop using this gourd and contact the manufacturer.
