Funzione del gruppo di regolazione della pista

Track Adjuster Assy is applicable for excavator, crane, bulldozer, motor grader etc full hydraulic crawler walking machine. The main function is realized the tension performance of the track shoe. When the track shoe assy walking, the track adjuster assy can generate a certain of pretension force, which make the front idler to be able to more flexible used. Nel frattempo, it can play an important role in buffering, when it meet the external force, it can avoid the track shoe from damage. Excavator Spring Tensioner Assy is equipped with a certain of degrees freedom, it can be used flexible.

After using the crawler driving gear of the Hydraulic Excavator some time, because the abrasion of the track chain pin and bushing, it make the pitch increase and whole track shoe extend, leading to track frame in rub, track shoe derail, the big noise of driving gear etc, thus influence the driving performance of the excavator. Perciò, each track shoe is necessary to install the track adjuster assembly for excavator, and making the track shoe always keep a certain of tensity.

Track Adjuster guaranteed that the track chain under the condition of original tensity,and make up for the track chain generating tensile deformation under the action of tension, as well as the telescopic deformation by the temperature difference. It also guaranteed that there has a certain of modest tension between the driving and the track adjuster.The track Adjuster normally install in the behind of the driving, where is the minimum tension. After track adjuster, it won’t have large decline under heavy load.It is including of track adjuster assembly, track adjuster cylinder, track adjuster recoil spring, oil lubricator, bolt etc.

Track Adjuster assy is process with special heat treatment, which let it in longer using life, and can under heavy load in greatest degree, and protect from breakage.Adopt low and high- double seal to let it always in lubrication, it’s fit for standard and special temperature application.Selecting a wide range of spring tension, high flexibility and hydrocarbon-type regulator, apply to mine working condition.
