CD, MD electric wire rope hoist to be inspected and accepted before shipment to the factory, inspection should be checked before the first wire rope hoist each lubrication point has added amount of lubricant, all parts are complete and intact. Fasteners are tightened. The slide and the wire wound on the reel correctly. Disconnecting the power circuit in the case, check whether the line is properly manipulated. Ensure that the drive mechanism is flexible. Check the formal acceptance test after a good start.
(1), no load test wire rope hoist
1, no load test should be carried out under the rated voltage and no load.
2, no load test should verify that:
a. rope electric hoist motor rotation;
b. limiter, control buttons,load chain and other electrical equipment, electromagnetic brake flexibility and reliability;
c. lift, whether the direction indicated by the direction control button;
d. deceleration institutions should be normal, no noise.
(2), static load test wire rope hoist
In the case of operating agencies do not move to 1.25 times the rated load of test crane, load elevated ground about 100mm, suspended for 10 minutes, should be stable and reliable, the sound normal, the load does not decline.
(3), wire rope electric hoist dynamic load test
1, at rated load test, agencies should be normal, after braking distance should not exceed the load down 80mm, brake response time exceeds this value adjustment.
2, more than 10% of the rated load for load test, repeated start lifting mechanism and travel agencies,hoist equipment should be achieved:
a. load does not fall;
b. smooth action, no jumps;
c. brake no noise, braking smooth and reliable;
d. temperature to normal, the brake magnet temperature does not exceed 80 ℃
