What are the precautions for maintenance and inspection of gantry cranes?

Single beam gantry crane is one of the important equipment for lifting. Next, the Shandong gantry crane manufacturer's editor will explain the inspection precautions for gantry cranes to everyone. We hope everyone will read it carefully.

1. Wheels

Whether there are fatigue cracks on the tread and axle of the gantry crane wheel, and whether the wear of the wheel tread and axle exceeds the standard. Is there any rail gnawing phenomenon during operation. What is the cause of rail gnawing.

2. Hook hook

Check whether the markings and anti detachment devices of the gantry crane hook meet the requirements, and whether the hook has defects such as cracks or peeling; Whether the wear and tear of the hook section, the increase in opening degree, and the twisting deformation exceed the standard; Check for fatigue deformation, cracks, and related pin and sleeve wear on the neck and surface of the hook.

3. Steel wire rope

Check whether the specifications and models of the steel wire rope match the pulley drum according to the design requirements. Whether the steel wire rope fixing devices such as pressure plates, rope clamps, and wedges at the fixed end of the steel wire rope meet the requirements. Whether the wear, breakage, twisting, flattening, bending, strand breakage, corrosion, etc. of the steel wire rope exceed the standard.

4. Roll drum

Whether there are fatigue cracks, damages, etc. on the drum body and edge; Whether the wear of the rope groove and cylinder wall exceeds the standard; Can the height of the drum rim match the number of winding layers of the steel wire rope; Whether the working conditions of the rope guide and rope guide meet the requirements;

5. Braking device

The setting of the gantry crane brake, whether the type of brake meets the design requirements, and whether the brake rod and spring have defects such as fatigue deformation and cracks; Whether the wear of the pin shaft, spindle, brake wheel, and brake friction plate exceeds the standard, and whether the hydraulic brake leaks oil; Whether the brake clearance adjustment and braking capacity meet the requirements.

6. Pulley

Is the pulley equipped with an anti slip groove device; Whether there are cracks, broken edges, excessive wear and tear on the pulley groove and rim, and whether the pulley of the gantry crane rotates flexibly.
