Cylinder: The cylinder is a hydraulic component responsible for adjusting the tension of the track.
It extends or retracts to control the track tension, ensuring that it remains within the specified limits.
Piston: The piston is located inside the cylinder and moves back and forth as hydraulic pressure is applied. This movement is what adjusts the tension of the track.
Spring Assembly: Many track adjuster assemblies include a spring assembly that works in conjunction with the hydraulic cylinder. The spring provides additional tension to the track, helping to maintain consistent tension as the machine operates.
Grease Fitting: Proper lubrication is essential for the smooth operation and longevity of the track adjuster assembly. A grease fitting allows for regular maintenance and lubrication of the assembly.
Functions of the Track Adjuster Assembly:
Tension Adjustment: The primary function of the track adjuster assembly is to adjust and maintain the tension of the tracks. Proper tension is crucial for ensuring that the machine can move efficiently and effectively across various terrains.
Track Alignment: By controlling track tension, the track adjuster assembly also helps in maintaining proper track alignment. Misaligned tracks can lead to uneven wear and decreased machine stability.
Shock Absorption: The assembly, particularly when equipped with a spring, can absorb shocks and impacts, enhancing the machine's stability and operator comfort.
Wear Reduction: Properly tensioned tracks experience less wear and tear, extending the lifespan of the undercarriage components and reducing maintenance costs.
Improved Traction: Well-maintained track tension ensures better traction, which is essential for excavators and construction equipment to perform effectively in challenging conditions.
Compatibility with Multiple Models:
The Hitachi EX100, EX120-1, EX120-2, EX120-3, EX120-5, and Zaxis ZX Series Track Adjuster Assembly is designed to be compatible with a range of Hitachi excavator models. This compatibility allows for easier replacement and maintenance of this critical component across various machines.
Quality and Reliability:
Hitachi is known for producing high-quality construction equipment, and their track adjuster assemblies are no exception. These assemblies are built to withstand the rugged conditions of construction and excavation work, ensuring durability and reliability.
