Explosion-proof electric hoist operation of the post operation technicians must strictly abide by; Enterprise information security risk management accounting system; Check and confirm before operation. Explosion-proof electric hoist the exposed explosion-proof parts of the hoist are made of special non-spark materials, and the explosion-proof performance is safe and reliable. Products through the ministry of machinery industry explosion-proof electrical products quality supervision and inspection center Jiamusi sub-center explosion-proof performance testing, and issued explosion-proof certificate.
1. Make necessary safety checks and preparations. Explosion-proof electric hoist the exposed explosion-proof parts of the hoist are made of special non-spark materials, and the explosion-proof performance is safe and reliable. Products through the ministry of machinery industry explosion-proof electrical products quality supervision and inspection center Jiamusi sub-center explosion-proof performance testing, and issued explosion-proof certificate.
2. For the crane that has been out of service for a long time, when it is re-used, it should be tested according to the provisions and confirmed that there is no abnormality before it can be put into use. Explosion-proof electric hoist the exposed explosion-proof parts of the hoist are made of special non-spark materials, and the explosion-proof performance is safe and reliable. Products through the ministry of machinery industry explosion-proof electrical products quality supervision and inspection center Jiamusi sub-center explosion-proof performance testing, and issued explosion-proof certificate.
3. Before starting the operation, check whether there are foreign bodies and obstacles affecting social work in the enterprises within the scope of walking ability on the crane track. After removing foreign bodies or obstacles, the operation can really start.
4. Check whether the pressure drop exceeds the specified value.
5. Check whether the operation button marks are consistent with the crane action.
6. Check whether the braking effect is good.
7. Check whether the risk rise limit position limiter is safe and reliable.
Check whether there is abnormal noise and vibration when lifting operation mechanism is idling.
9. Check whether the lifting explosion-proof electric hoist is faulty or damaged.
10. Check whether there is fault and damage in the development of hoisting explosion-proof electric hoist.
11. Before starting, carefully check whether the mechanical, electrical, explosion-proof electric hoist, clamp and plug of the equipment are in good condition and reliable.
Figure 12. Do not overload the crane. Explosion-proof electric hoist, when hands are not allowed to grasp between rope and object.
13. When lifting objects, the safety operation rules of hook lifting heavy industry must be observed. Should be tied tightly, and in the object at the sharp gap set cushion protection.
14. Use electric control switch of drag line to start, and insulation technology must be good.
