SUPERIOR IMPACT ABSORPTION AND PROTECTION SYSTEM

The recoil spring is typically located inside the track frame or track adjuster assembly, working in conjunction with the recoil cylinder to absorb and distribute the forces generated during excavator operation, including digging, lifting, and traveling.

This critical assembly allows for controlled track tension while absorbing impacts to the undercarriage without transferring force to sensitive components like final drives and sprockets. As an impact absorption device, the recoil spring contracts upon impact while continually providing measured tension in the track through the control of a cylinder. 

ADVANCED SURFACE TREATMENT FOR EXTENDED LIFESPAN

The surface of the recoil spring cylinder must be chrome-plated for enhanced resistance to wear and corrosion. The material selected for cylinder production is typically a classic tempered steel containing a specific percentage of carbon to achieve maximum toughness.

The quality and efficiency of recoil springs depend significantly on their production process, which typically progresses through three critical
Pphases: forming (either cold or hot), heat treatment, and post-treatment. In hot forming, the bars are heated to approximately 930°C before winding, then cooled in oil and hardened. 

COMPREHENSIVE UNDERCARRIAGE PROTECTION SYSTEM

The excavator recoil spring, also known as a track adjuster spring or tension spring, is a vital component of an excavator's undercarriage system responsible for providing tension and maintaining proper track tension on the excavator's tracks (whether crawler tracks or rubber tracks). 

UNIVERSAL COMPATIBILITY DESIGN

Direct OEM replacement specifications ensure perfect fit across all major excavator models in the 10-50 ton class with no modifications required, simplifying inventory management and maintenance planning.
