7. Some tips:
①Check thehook
There is not crackle in hook of single girderbridge crane and sliding wheel shaft. Thread does not appearloose, bearing does not abrade and a crack must be replaced immediately. Afterthe plate hook riveting, The gap between the plate and the plate is no more than 0.3mm. When the degree of critical section is more than 10% of the original height, that should be replaced.To do the hook test after maintenance, lift upthe object with rated load of 1.25 times lasting for 10 minutes. As a result, the elastic opening of the hook is lower than the 0.25% of the size of thehook. And there is no permanent deformation and cracks after unloading.
②Check the wire rope
Check the number of broken wires in 1 lay. If more than 10% of the total number of steel wire, it should be replacement. When the attrition rateof steel wire is higher than that of the original diameter 40%, the whole wire rope is treated as scrap. The shrinkage of wire rope to 70% of the diameter ofthe rope and the rope core exposed, it should be scrapped. Clean the wire rope with kerosene. Use wire rope grease dip and coating to saturation.
③Repair of pulley block
The pulley shaft cannot crack. The attrition rate of shaft neckshould be no more than 30% of the original diameter, the degree of conic is nothigher than 5%. If all the conditions are not met, it should be replaced. Check pulley groove shape according to sample. Wear is not higher than the wallthickness of 30%, otherwise it is discarded and replaced.
After crane overhaul, the shaft hole of the defect cannot begreater than 0.25cm² and the depth is less than 4mm.
④Hoist roller
When the lever of rope groove wear is higher than 2mm, it shouldbe replaced. The thickness of the roller is not less than 81% of the originalthickness after the overhaul. The center line of the roller shaft keep parallelwith the bearing surface and center line in the two ends of the roller deviateless than 0.15mm.
Ensure that there is no crack on the surface of the roller, the degree of loss of roundness is not obvious and the clamp screws should betightened. There is no crack on the roller shaft. After the overhaul, if thedegree of wear isn’t higher than that of 5% of the original standard diameter,it should be replaced.Prior to impregnation 100%of our stators are tested. The test is executed according to DINEN60204-1(VDE0113) for the following:
Resistance between phases
Inductance of phases by an impulse voltage
Insulation between windings and PE with resistance measurement
Breakdown voltage (high voltage 2500V tester) 
Completed motors are high voltage tested according to VDE0530: (test durationtime: 1 sec.)
UTest = (2 x UNom + 1000V) x 1.2
Optional encoders are available in European electric wire rope hoists (for frequency converter motors for variable speed control) and mounted directly to the fan shroud.
