How To Use And Maintain The Purchased 10 Ton Electric Hoist?

How To Use And Maintain The Purchased 10 Ton Electric Hoist?
 

1. For electric hoists that are newly installed or installed after dismantling and inspection, they should first be tested with an empty car for several times. But before the installation is completed, it is forbidden to turn on the power for trial run.
 

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 whether it is normal.
 

3. The dynamic load test is based on the rated load weight for repeated lifting and left and right moving tests. After the test, check whether the mechanical transmission part, electrical part and connection part are normal and reliable.
 

4. In use, it is absolutely forbidden to use it in an environment that is not allowed, and when it exceeds the rated load and the rated closing times (120 times) per hour.
 

5. During installation, commissioning and maintenance, it is necessary to strictly check whether the limit device is flexible and reliable. When the hook is raised to the upper limit position, the distance between the hook shell and the reel shell must be greater than 50mm (10t, 16t, 20t must be greater than 120mm). When the hook is lowered to the lower limit position, the safety ring of the wire rope on the reel should be ensured, and the effective safety ring must be more than 2 turns.

6. It is not allowed to press two flashlight door buttons that make the electric hoist move in opposite directions at the same time.
 

7. After the work is completed, the main switch of the power supply must be opened to cut off the power supply.
 

8. The electric hoist should be operated by a special person, and the operator should fully grasp the safety operating procedures, and it is strictly forbidden to pull and hang it crookedly.
 

9. The electric hoist must be inspected regularly by specialized personnel during use, and timely measures are taken when faults are found, and carefully recorded.
 

10. When adjusting the braking slide of the electric hoist, it should be ensured that under the rated load, the braking slide is S≤V/100 (V is the stable lifting distance of the load within one minute).
 

11. Scrapping standards for steel wire ropes: The inspection and scrapping standards for steel wire ropes are implemented in accordance with CB/T5972-1986 "Practical Specifications for Inspection and Scrapping of Steel Wire Ropes for Hoisting Machinery".
 

12. The electric hoist must maintain enough lubricating oil during use, and keep the lubricating oil clean, and it should not contain impurities and dirt.
 

13. When oiling the steel wire rope, use a hard brush or a small wooden piece. It is strictly forbidden to directly oil the working steel wire rope by hand.
 

14. When the electric hoist is not working, it is not allowed to hang heavy objects in the air to prevent permanent deformation of the parts.
 

15. During use, if a fault is found, the main power supply should be cut off immediately.
 

16. Special attention should be paid to the wearing parts during use.
 

17. After a long period of continuous operation, the 10-20 ton hoist may automatically cut off the power. This is the overheating protection function of the motor. At this time, it can be lowered. After a period of time, the motor can continue to work after it cools down.
 

18. The use and management shall be carried out in accordance with Article 4 of JB9009-1999 "Safety Regulations for Wire Rope Electric Hoists".
 

19. Inspection and maintenance shall be carried out in accordance with Article 5 of JB9009-1999 "Safety Regulations for Wire Rope Electric Hoists".
