1、 Maintenance and care of metal structures

The first step is to inspect the main beam, which should be checked every ten days. Check whether there are any open welding cracks in the connecting welds, and whether there is any remaining deformation or instability in the main beam. If any results are found, the use should be suspended and corrected.

2、 Maintenance and upkeep of primary components

1. The steel wire rope should be slid once every two weeks, and dirt should be removed before lubrication.

2. If any twisting joint of the steel wire rope is found, and more than 6 cracks are found, it should be immediately invalidated and replaced. (Daily pre shift inspection)

3. When the wheel wear exceeds 15% of the original thickness or cracks, it should be replaced.

4. The accelerator should not be short of oil and should be regularly replaced. Any abnormalities or noise should be promptly repaired.

5. The brake of the lifting organization should be checked once before each use, and the brake of the operating organization should be checked once a day before use.

6. The secondary progress adopts an electric hoist, but due to improper operation during use, it may cause loose parts, metal fatigue, and other reasons. It is particularly emphasized to check it once a week and carefully record it.

3、 Maintenance and care of electrical equipment

1. This task is completed by a professional electrician from the gantry crane manufacturer, and an electrician maintenance record is filled out.

2. Persist in cleaning electrical equipment, such as resistors, control screens, touch sensors, etc. Eliminate external dust and dirt to prevent the occurrence of adverse phenomena such as electric leakage, breakdown and short circuit. Electricians conduct daily inspections and fill out duty records.

3. Regularly investigate whether the motor rotor can slide and the electric brush can be touched.

4. Can the sound of retracting electric motors, electromagnets, circuit breakers, electromagnetic switches, etc. be normal.

5. When the operating conditions are harsh, the insulation resistance of the motor and wires should be measured regularly. Attention from gantry crane manufacturers: conductive sliding wires, bracket insulation, and grounding of various casings.

6. The rail clamp and connecting bolts of the electric hoist may become loose during operation, so it is necessary to carefully inspect each part once a week.

In addition to standardized use, daily maintenance is also important for gantry cranes.
