Specific safety operation rules for explosion-proof electric hoist
Explosion-proof electric hoist can meet the requirements of precision loading and unloading, sand box mold clamping, machine tool maintenance and other delicate operations. It is suitable for occasions where there are specified flammable gases and explosive mixtures formed by steam and air in the workshop. It has the characteristics of compact structure, light weight, small volume and large lifting capacity, but do you know how to operate it more safely? Then let's introduce: the specific safety operation rules of explosion-proof electric hoist:
1. Electric hoist operators must be trained, and those without training are not allowed to operate at will.
2. Check whether the switches, electrical appliances and mechanical parts are in good condition before use.
3. Before lifting the workpiece, start the empty car, check the limiter, and start working after normal operation.
4. When lifting the workpiece, it must be hung firmly and steadily, and it must be slightly off the ground before lifting. After trial lifting, there is no problem before lifting.
5. It is not allowed to use inclined lifting and horizontal dragging tools.
6. It is not allowed to use it for tilting lifting and horizontal dragging, and it is strictly forbidden for the hanging objects to pass over the head of the personnel.
7. It is strictly forbidden to hang heavy objects at the tip of the hook or the hook is not firmly lifted.
8. When lifting the workpiece, check whether the spreader meets the regulations, and must not be overloaded.
9. The limit is a safety device to prevent the hook from rising and falling. It is strictly forbidden to use the limit as a switch.
10. It is strictly forbidden to hang the load in the air for a long time.
11. After the work is completed, open the electric hoist to a fixed position and cut off the power
12. The explosion-proof electric hoist must be operated by a special person, and the operator should master the relevant explosion-proof safety regulations.
13. The explosion-proof electric hoist should be checked at least once every 10 days, and measures should be taken if any fault is found and recorded.
14. The power must be cut off before checking the explosion-proof motor, brake, magnetic starter and limit switch.
15. The wire rope of explosion-proof electric hoist should be lubricated at least once every 10 days.
16. The explosion-proof electric hoist should be parked after use, and the hook should be raised to a sufficient height from the ground to avoid affecting the activities of ground personnel.
