Winter XCMG truck crane maintenance method 1, external maintenance of XCMG truck crane 2, truck crane tire maintenance 3, XCMG truck crane battery maintenance 4, XCMG truck crane air conditioning maintenance 5, XCMG truck crane engine maintenance 6, truck crane electrical equipment maintenance. The following is the crane parts maintenance technology display.
1. Maintenance of motor and reducer
Xugong crane parts maintenance technology to master the essence, first of all, often check the temperature of the motor shell and bearing parts, motor noise, vibration and no abnormal phenomenon.
In the case of frequent startup, the temperature rise of the motor will increase quickly due to the reduction of ventilation cooling capacity caused by low speed and large current. Therefore, it should be noted that the temperature rise of the motor shall not exceed the upper limit specified in its manual.
Adjust the brake according to the motor instruction.
The daily maintenance of reducer can refer to the operation manual of the manufacturer. And should often check the reducer anchor bolt, the connection shall not be loose.
2. Lubrication of walking device
Secondly, xUGong crane parts maintenance technology to remember good fan lubrication, such as when using should first open the reducer ventilation cap, to ensure good ventilation, to reduce internal pressure. Before working, check whether the height of the lubricating oil surface of the reducer meets the requirements. If it is lower than the normal oil surface, add the same type of lubricating oil in time.
The bearings of each wheel of the walking mechanism have been filled with enough grease (calcium based grease) during assembly, and do not need daily refueling. Grease can be added once every two months through the oil filling hole or opening the bearing cover, and grease can be unloaded, cleaned and replaced once a year.
Grease shall be applied at the engagement of each open gear once a week.
3, Hoist group maintenance and maintenance
Regularly observe the reducer oil window, check whether the lubricating oil level is in the specified range, when lower than the specified oil level, should be timely added lubricating oil.
When the crane is not used frequently and the sealing condition and the use environment is good, the lubricating oil in the reducer box should be replaced once every six months, and when the use environment is bad, it should be replaced once every quarter. When it is found that there is water in the box or foam on the oil surface all the time and it is confirmed that the oil has deteriorated, the oil should be changed immediately. When changing oil, the oil should be replaced strictly according to the operation manual of the reducer, and the mixed use of oil should be avoided.
