Note (1) before the inspection a. Within walking distance operator, sight should be no obstacle on the route and litter weights through. b. Manual button up and down, left and right directions shall act accurate and sensitive electric hoist motor and gear should be no abnormal sound. c. brakes should be sensitive and reliable. d. There should be no foreign matter on the hoist orbit. e. the upper and lower limiter action should be accurate and sensitive. f. hook nut should be securely fastened stopper. g. Hook in the horizontal and vertical directions of rotation should be flexible. h. hook pulley should be flexible rotation. i. the rope should be no cracks, neatly arranged on the drum hoist 2t, without disengaging the pulley groove, chaotic twisting, folding buckle and other signs of good lubrication. j. Hanging aids no anomalies. k. hoist working temperature of -25 ~ + 40 ℃ l. hoist does not apply to places full of corrosive gases or the relative humidity greater than 85%, not a substitute for proof hoists, lifting molten metal or not toxic, flammable and explosives. (2) may not be the side hoist crane unloading heavy ksy hoist, prohibit the use of overload. (3) In use, the operator should always check whether there Labelling rope, tie a knot, out of the groove, wear and so on, if there should be immediately removed, and should always check the rope guide and limit switches are secure and reliable. (4) shall not artificially limit the use in their daily work to stop or stop heavy lifting equipment running. (5) After work is completed, turn off the power switch, cut off the main power supply. (6) should set up a special weekly maintenance personnel hoist major performance and safety status check once and find fault and remove. 9. Use the hoist must be checked regularly hz hoist by specialized personnel, found fault timely measures, and recorded carefully. 10. adjust the amount of electric hoist brake the decline, should ensure that the rated load, the amount of brake decline 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. 13. oiled rope should use a stiff brush or wood chips, 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, then you can decrease over time, to continue to work until the motor cooled down. kadu electric hoist electric hoist _ _ Xinyang Henan generous inexpensive by heavy machinery Limited.
