1、 Maintenance of metal structure
First, check the main beam every ten days. Check whether the connecting weld has open welding cracks, and whether the main beam has residual deformation and instability. If any results are found, the application should be suspended and corrected.
2、 Maintenance of primary parts
1. The steel wire rope should be lubricated once every two weeks, and the dirt should be eradicated before lubrication.
2. As usual, if there are more than 6 cracks found at any twist joint of the steel wire rope, it should be discarded and updated immediately. (daily pre shift inspection)
3. When the wheel wear exceeds 15% of the original thickness or there is cracking, it should be renewed.
4. There should be no lack of oil in the accelerator, and it should be exchanged regularly. In case of abnormalities and noise, it should be repaired in time.
5. The brake of the lifting organization shall be checked before each use, and the brake of the operating organization shall be checked before each use.
6. The electric hoist is used in the auxiliary progress. Due to improper operation in the use, it leads to loose parts, metal fatigue and other reasons. It is particularly emphasized to check once a week and record it carefully.
3、 Maintenance of electrical equipment
1. This task is completed by the professional electrician of the gantry crane manufacturer, and fill in the electrician's maintenance record.
2. Keep electrical equipment clean, such as resistors, control screens, touch devices, etc. Eradicate external dust and dirt, and prevent the occurrence of bad scenes such as electric leakage, breakdown and short circuit. The electrician shall check every day and fill in the duty record.
3. Frequently investigate whether the sliding wire and brush of the motor rotor can be touched.
4. Whether the retraction sound of motor, electromagnet, circuit breaker, electromagnetic switch, etc. is normal.
5. When the operation conditions are bad, the insulation resistance of motors and wires should be measured regularly. Attention of gantry crane manufacturers: conductive sliding wire, support insulation and various shell grounding.
6. The rail clamp of the electric hoist and the connecting bolts of each component will be loose in the effect, so it is necessary to carefully check each part once a week.
In addition to the standardized use of gantry cranes, daily maintenance is also very important.
