Maintenance points of rubber tyred gantry crane in cold weather
1. Maintenance of electric motors and reducers
Firstly, it is necessary to regularly check whether the temperature of the motor casing and bearing parts is normal. Is there any abnormal phenomenon in the noise and vibration of the electric motor. It should be noted that the temperature rise of the motor should not exceed the upper limit value specified in its manual. Adjust the brake according to the requirements of the motor user manual. The daily maintenance of the gearbox can refer to the manufacturer's user manual. And the foundation bolts of the reducer should be checked regularly, and the connection should not be loose.
2. Lubrication of the walking device
Secondly, when maintaining SEVENCRANE rubber tyred gantry crane components, attention should be paid to the lubrication of the gearbox. When using, the ventilation cap of the reducer should be opened first to ensure good ventilation and reduce internal pressure. Before starting work, check whether the lubricating oil level of the gearbox meets the requirements. If it is lower than the normal oil level, the same type of lubricating oil should be added timely.
The bearings of each wheel of the walking mechanism have been filled with sufficient lubricating grease during assembly, and do not require daily refueling. Lubricating grease can be replenished every two months by filling the oil hole or opening the bearing cover. Disassemble, clean, and replace the lubricating grease once a year. Apply lubricating grease to the meshing points of each type of gear once a week.
