The use and maintenance of electric hoist is an important factor affecting its service life, which is an extremely important factor in addition to product quality. Therefore, if you want the electric hoist to have a long life, you need to do a good job in the use and maintenance of the electric hoist.
- Before normal use of the electric hoist, an empty test run should be carried out, and 25% of the rated load should be lifted, lifted to about 100 mm above the ground, and tested for a static load test for 10 minutes, and check whether it is normal.
- The dynamic load test is to repeat the lifting and moving of the heavy object from the left and right by 10% over the rated value. After the test, check whether the mechanical transmission electrical part and the connection part are normal and reliable.
- In use, it is absolutely prohibited to use it in an unallowable environment and when it exceeds the rated load and the rated number of closings per hour 12 times.
- It is not allowed to tilt the lifting load and use it as a drag tool.
- During work, the operator should always pay attention to the undesirable situation of the steel wire rope falling off the groove on the reel or winding two layers and eliminate it in time. .
- The fire stopper is prepared to prevent the hook from exceeding the limit and reduce accidents. Therefore, the fire stopper cannot be used frequently.
- It is forbidden to press two flashlight door buttons that make the electric hoist move in opposite directions at the same time.
- After the work is completed, the main switch of the power supply must be opened to cut off the main power supply.
- The electric hoist should be operated by a dedicated person, and the operator should have a deep grasp of the safe operation regulations.
- The electric hoist should be inspected by a dedicated person at least once every ten days, and measures should be taken in time when any fault is found, and carefully recorded.
- Do not allow oil stains on the moving ring of the brake.
- The brake is adjusted with a compression nut until the heavy object can easily be suspended, and the braking distance is extended under the maximum load, and should not exceed 80 mm.
- In the course of use, if a bad fault is found, the main power supply should be cut off immediately.
- It should be ensured that the electric hoist has enough lubricating oil. After the installation is complete, add lubricating oil according to the lubrication instructions and check whether the lubrication is in good condition, and ensure that the lubricating oil is clean and free of impurities and dirt.
- You must be careful to apply the lubricating oil directly to the working wire rope by hand, because the burrs and cracks on the wire rope surface at this time will seriously hurt your hands. When oiling, you should use a stiff brush or use a planed and clean wooden board. . In winter, due to the low temperature, when the steel wire rope is oiled, the lubricating oil is first heated and deepened.
- When there is significant wear on the surface of the wire rope, the maximum number of wire rope breaks should be appropriately reduced.
- Special attention should be paid to the condition of vulnerable parts during the inspection.
- When the electric hoist is not working, it is not allowed to hang heavy objects in the air to prevent deformation of the parts.
- When the electric hoist is used up, it should be parked at the designated place, and the hook should be raised to a position above 2 meters above the ground.
