Shandong Zhulin Intelligent Manufacturing Co.， Ltd.， as a professional manufacturer of hydraulic excavators in the "Four Wheel Belt"， actively participates in the 16th China （Beijing） International Exhibition of Engineering Machinery， Building Materials Machinery， and Mining Machinery

When one side of the track falls off， first connect the drive wheel， lift the upper track with a bucket， align the drive wheel and enter the inside of the track， adjust the alignment of the drive teeth with an iron rod， and align the upper drag wheel. This step has been completed by one-third.

With the continuous increase of excavator working hours， the excavator track link pins and bushings have some wear during normal operation， causing a decrease in track tension. Therefore， reasonable adjustment of track tension can provide stable driving force for excavator walking， and to some extent， improve the service life and work efficiency of the shoe belt. Therefore， the tension of the track needs to be adjusted according to different working conditions.

Composed of the "Four Wheel Belt". （i.e. driving wheel， guide wheel， supporting wheel， supporting wheel， track）， a hydraulic transmission track walking device， is controlled by a walking motor installed on two tracks and supplied with oil by a hydraulic pump on the third platform， making it easy to turn or turn on site.
