Maintenance technology of Crane parts of XCMG
Winter Maintenance methods of XCMG Crane 1. External maintenance of XCMG crane 2. Tire maintenance of XCMG Crane 3. Maintenance of battery of XCMG Crane 4.The following is the crane component maintenance technology display.
1. Maintenance of motor and reducer
To master the essence of maintenance technology of XCMG crane components, it is necessary to regularly check the temperature of the motor shell and bearing parts, as well as the noise and vibration of the motor.
In the case of frequent starting, the ventilation cooling capacity is reduced due to low speed, and the current is large, so the temperature rise of the motor will quickly increase. Therefore, it should be noted that the temperature rise of the motor should not exceed the upper limit specified in the specification.
Adjust the brake according to the motor manual.
The daily maintenance of the reducer can refer to the operating instructions of the manufacturer.And should always check the reducer of the anchor bolt, the connection must not be loose.
2. Lubrication of the walking device
Secondly, XCMG crane components maintenance technology to remember good fan lubrication, such as the use of the reducer ventilation cap should be opened to ensure good ventilation, in order to reduce internal pressure.Before work, check whether the lubricating oil level of reducer meets the requirements. If it is lower than the normal oil level, add the lubricating oil of the same type in time.
The bearing of each wheel of the walking mechanism has been filled with enough grease (calcium based grease) during the assembly without daily refueling. The grease can be replenished once every two months through the oil filling hole or by opening the bearing cover. The grease can be disassembled, cleaned and replaced once a year.
Apply grease to each open gear meshing once a week.
3. Maintenance and maintenance of hoist group
Frequently observe the oil window of the reduction box, check whether the oil level of the lubricating oil is within the prescribed range, when it is lower than the prescribed oil level, you should replenish the lubricating oil in time.
In the case that the crane is not used frequently and the sealing condition and the use environment are good, the lubricating oil in the reducer should be replaced once every half a year, and once every quarter when the use environment is bad.When water or foam is found in the tank and the oil level is determined to be deteriorated, the oil should be changed immediately.When changing oil, the oil shall be changed in strict accordance with the operating instructions of the reducer, and the mixed use of oil shall be avoided by all means.
