    Analysis of seal leakage of roller
    Roller is an important load-bearing part of crawler construction machinery (commonly known as "lower roller"), which is composed of roller body, supporting shaft, left and right supporting seat and sealing components. The supporting shaft is fixed on the platform frame through the left and right supporting seats. There is a pressed shaft sleeve in the wheel body to rotate with the supporting shaft. A sealing component is installed between the rotating wheel body and the fixed left and right supporting seats to keep the lubricating oil seal between the supporting shaft and the shaft sleeve. The sealing assembly is composed of a pair of double conical metal sealing rings and two butadiene rubber fixed compression rings. The rubber ring is respectively installed in the sealing seat mouth of the wheel body and the support seat. Because the metal sealing ring bears the extrusion support of the rubber ring and makes its annular blade belt closely mesh in rotation, the seal belongs to the flo

    How to effectively extend the life of construction machinery crawler?
    1. Causes of track damage 1) If the stones in the track are not removed in time, soil or gravel will roll into the track and be squeezed between the guide wheel, drive wheel and track when the track rotates, which will make the track elongate. When the extrusion force in the track exceeds the bearing force of the chain rail, the chain rail will break. If the soil or gravel is rolled into the chain rail, the guide wheel and the supporting wheel will not be controlled by the rail chain, and the track will be formed. At this time, if the driver forces the track to derail instead of loosening the tension cylinder of the track, the track is easy to break, and the wear of the track and the four wheels (guide wheel, supporting wheel, carrier roller and driving wheel) will be accelerated.

    Track maintenance, bottom maintenance can not be ignored
    ​To do a good job in the maintenance of the equipment can maintain the good performance of the crawler crane equipment, increase the service life of the equipment, reduce the possibility of accidents in the operation of the crawler crane, so as to reduce the delay of work and obtain better economic benefits. First of all, we should have a deep and detailed understanding of the mechanical equipment used, carry out regular and irregular inspection in the daily operation process, make clear the deficiencies and design defects of the equipment, make a detailed analysis of the existing problems and defects, and determine the appropriate maintenance methods. Regular and proper maintenance is one of the conditions to keep crawler crane running healthily.
