9. Use the hoist must be checked regularly by specialized personnel and found that failure to take timely measures, and recorded carefully. 10. adjust the amount of electric hoist brake the decline, should ensure that the rated load hoist brake decline in the amount of S≤V / 100 (V for the load within the next minute and stable lifting of the distance). 11. scrapped rope: rope examination and discard criteria according to CB / T5972-1986 "Lifting wire rope inspection and scrap of practice" implementation. 12. Use hoist must be kept enough oil, lubricating oil and keep clean, should not contain impurities and dirt. You should use a stiff brush or a small piece of wood hand hoist rope 13. oiled, non-direct hand rope to a working oil. 14. electric hoist does not work, do not allow the weights suspended the air, preventing permanent deformation of parts. 15. During use, if we find fault, should immediately cut off the main power supply. 16. Use should pay special attention to the vulnerability of the situation. 17.10 ~ 20 t hoist after long time continuous operation, automatic power-off phenomenon may occur, which is a function of the motor overheating protection gh electric hoist, this time may be reduced over a period of time, we can continue to work when the motor cool down. Before the use of electric hoist electric hoist inspection prior to use, simple security checks are necessary to avoid some unusual problems 0.3 parts hoist, ahead of danger prevention. 1. The operating handle buttons control the direction and the brake and stopper are sensitive and accurate. 2. The wire rope no defects, oiled, arranged in neat rows. The motor and gear rotation for any abnormal sound. The hoist rails and personnel walking area with no obstructions. 5. hook and pulley be flexible rotation. 3 electric hoist, electric hoist rock, provided by the industry's leading heavy machinery Co., Ltd., Henan Province, generous.
