Due to the special nature of the operating environment and the high requirements for personal safety, Explosion-proof electric hoist undergoes rigorous testing before leaving the factory. The test contents of explosion-proof electric hoists mainly include type tests, routine tests, medium tests, sampling tests, life tests, and durability tests, which are tests conducted before each qualified explosion-proof electric hoist leaves the factory.
Specific Safety Operating Procedures for Explosion-Proof Electric Hoists:
1. Before operation, explosion-proof electric hoist operators must receive training; untrained personnel are not allowed to operate.
2. Before use, confirm that the switches, electrical components, and mechanical parts are not damaged.
3. Before lifting the workpiece, start the hoist without a load, check the limiters, and begin work after normal operation is confirmed.
4. When lifting workpieces, hang them securely and steadily; ensure sufficient clearance from the ground before lifting. Test the lift before fully raising.
5. Tilted lifting and horizontal dragging are not permitted.
6. Horizontal dragging with a crane is not allowed, and it is strictly forbidden for the crane to pass over people's heads.
7. It is strictly forbidden to hang heavy objects at the end of the hook or to tightly bind the hook.
Explosion-proof electric hoist It is explosion-proof lifting equipment designed according to explosion-proof standards, with an explosion-proof type of "explosion-proof type". The exposed explosion-proof components of the explosion-proof electric hoist are made of special spark-free materials.
Improper starting and operation methods of explosion-proof electric hoist cranes may cause accidents due to crane sway. When the crane is running, the crane operator stabilizes the object behind the electric hoist, operating under the direction of heavy industry personnel to navigate obstacles. When the heavy object begins to rise and the wire rope or chain is taut, stop the hoist, reposition the hook in the direction of the swing, and confirm the secure hanging of the load. Avoid excessively rapid lifting; only increase the lifting speed after the load clears obstacles. Explosion-proof electric hoist Do not operate intermittently; maintain continuous power supply during long-distance operation. Keep the load stable during operation; avoid swaying or swinging.
