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

b. the up and down, left and right directions of the manual buttons should be accurate and sensitive, and the motor and reducer should have no abnormal sound

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

(4) in daily work, it is not allowed to artificially use the stopper to stop the lifting of heavy objects or the operation of equipment

(the other end is fixed with the cover fixed into a body with the head; the screw nut and the arch frame are fixed with bolts 5) after the work is completed, 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 the faults should be eliminated in time

(7) the brake ring on the brake wheel of the motor fan shall not be stained with oil dirt, and the adjusting nut shall be fastened to avoid accidents due to brake failure

(8) add an appropriate amount of lubricating oil to each lubricating part of the electric hoist in time. The lubricating oil should be clean and free of other impurities. The lubricating oil should be replaced every two months. When the time of lifting reducer and operation comes to 2018, the traveling reducer must be lubricated sufficiently before use

(9) in the process of use, if a fault is found, the main power supply should be cut off in time

(10) when the electric hoist is not working, it is not allowed to hang heavy objects in the air to prevent permanent deformation of parts

(11) the use of electric universal testing machines in all walks of life promotes the vigorous development of China's testing machine market. After the use of gourds, they should be stopped in a designated safe place. Rain cover shall be set outdoors

(12) it is forbidden to press two buttons in opposite directions at the same time, and others can be operated at the same time

(13) when repairing the lifting reducer, do not use a screwdriver, flat shovel, etc. to hit the joint surface. Gently tap the protruding part of the box with a wooden hammer to avoid damaging the sealing plane of the box and the box cover
