Electric wire rope hoist hoisting and maintaining safety standards
Wire rope electric hoists are divided into single-phase and three-phase electricity, which provide a lot of convenience for people's life and work. The safety standards for hoisting and maintenance of wire rope electric hoists are as follows:
1. Electric wire rope hoist is not suitable for lifting molten metal or toxic, flammable and explosive materials.
2. The electric hoist shall not be hoisted or unloaded from the side, and overloaded use is prohibited.
3. During use, the operator should always check whether the steel wire rope has random buckles, knots, grooves, wear, etc. If it occurs, it should be eliminated in time, and the rope guide and limit switch should be checked frequently for safety and reliability.
4. Do not artificially use the stopper to stop the lifting of heavy objects or stop the operation of the equipment in daily work.
5. After finishing the work, turn off the main power switch and cut off the main power supply.
6. Special maintenance personnel should be assigned to check the main performance and safety status of the electric hoist once a week, and troubleshoot the fault in time.
7. The brake ring on the motor fan brake wheel must not be stained with oil, and the adjustment nut should be tightened to avoid accidents due to brake failure.
8. The lubricating parts of the electric hoist should be added with appropriate amount of lubricating oil in time. The lubricating oil should be clean and free of other impurities. The lubricating oil is changed once every two months. Sufficient lubricating oil must be added to the lifting reducer and running reducer before use.
9. During use, if any fault is found, the main power supply should be cut off in time.
