Precautions for no-load test of gantry crane

Gantry crane is a kind of lifting equipment with high technical content and complicated operation. Usually after the gantry crane equipment is idle or installed, no-load test is required before it is put into use, mainly to check whether the quality of the equipment meets the safety requirements. Construction requirements. During the no-load test of the gantry crane, the following points should be paid attention to:

1.  Pay attention to whether the current, voltage, etc. meet the requirements.
2.  Test whether the stopper is in good condition and whether the phase error protection function is good.
3.  Test whether the assembly quality of the rope device is good. When the wire rope is in a tight state, start the gantry crane lifting mechanism to make the hook descend. After rotating the drum twice, the wire rope should be able to be discharged from the rope guide port smoothly.
4.  Check the axial movement of the conical motor shaft. During operation, use visual inspection to judge the axial movement and judge whether the movement is within the allowable range. If the gap does not meet the gap, it should be adjusted in time.

The no-load test of the gantry crane is to check whether each operating mechanism is normal and whether there is abnormal sound. After confirming that it is normal, perform the heavy-load test, and then after the acceptance by the quality inspection department, the certificate of conformity can be issued before it can be officially put into use.
