Precautions for the use of wire rope electric hoist

wire rope electric hoist is a small lifting equipment. When using electric hoist for operation, it is necessary to do a good job in the inspection before and after use, so as to avoid safety accidents What are the precautions for the use of wire rope electric hoist

(1) check before use

a. there should be no obstacles within the walking range of the operator and on the route through which the weight passes

c. the extruder should be sensitive and reliable when braking the plastic to melt it

d. there should be no foreign matters on the running track of the electric hoist

e. the action of the upper and lower limit positioner should be accurate

f. the hook stop nut should be fastened

g. the hook shall rotate flexibly in horizontal and vertical directions

h. the hook pulley should rotate flexibly

i. the steel wire rope should have no obvious defects, be neatly arranged on the drum, have no signs of disengaging the pulley groove, and be well lubricated

j. there is no abnormality in the lifting AIDS

k. the working environment temperature of the electric hoist is - 25 ~ +40 ℃

(2) the electric hoist shall not be lifted or unloaded by side, and overload use is prohibited

(3) in the process of use, the operator should always check whether the steel wire rope is buckled, knotted, grooved, worn and other phenomena. If they occur, they should be eliminated in time, and should often check whether the rope guide and limit switch are safe and reliable
