2474315 Crawler Tensioner Cylinder for W200

Product Introduction:

The track tensioner in the traveling system of a milling machine is a core component ensuring the normal operation of the track. Installed at the end of the track traveling mechanism, it mainly maintains the proper tightness of the track. It adjusts the track's tightness through hydraulic or mechanical structures, preventing the track from falling off or deviating due to being too loose, or increasing traveling resistance and aggravating component wear due to being too tight. During operation, the track tensioner can buffer road shocks, reduce meshing loss between the track and driving wheels or guide wheels, and improve the stability and service life of the traveling system. It has a reliable sealing structure, able to adapt to dusty and muddy environments at construction sites, and is easy to maintain. Its tension can be quickly adjusted according to working conditions, making it a key accessory to ensure the milling machine walks continuously and stably and completes milling operations smoothly.

What are the common faults?

Common faults of the milling machine track tensioner include abnormal track tightness, seal oil leakage, failure to maintain tension, and abnormal noise or vibration. For overly loose/tight tracks, check the tension cylinder oil pressure, spring condition and clear stuck sand; for oil leakage, replace aged oil seals and clean the cylinder inner wall; for tension failure, inspect one-way valve jamming or cylinder piston wear; for noise/vibration, tighten loose bolts and replace damaged idler wheel bearings. These faults are mostly related to component aging and impurity jamming; timely troubleshooting ensures stable operation of the traveling system and extends track service life.

How to determine if the tension of the track tensioner of a milling machine is normal?

To judge whether the tension of the milling machine track tensioner is normal, combine visual inspection, practical testing and auxiliary measurement: during visual inspection, observe the track sag—under normal working conditions, the sag at the middle of the track should be moderate without excessive looseness or tightness; pull the track by hand, if it shakes easily without jamming, the tension is reasonable—excessive looseness causes slipping, while over-tightness makes pulling difficult. In practical testing, observe during no-load driving: if the track has no deviation, abnormal noise or vibration, and no jamming when turning, the tension is suitable; you can also touch the tension cylinder—no abnormal heating during operation indicates stable oil pressure. In addition, refer to the equipment manual and measure the gap between the track and idler wheel with a feeler gauge; it is normal if it meets the marked range, and tension adjustment is needed if it deviates.
