When your excavator vibrates violently on a bumpy construction site, when cab noise erodes your operator's stamina, and when frequent spring replacements become a hidden cost—you need more than just a spare part, a truly reliable "engineering backbone"!
The ECHOO KX161-3 spring assembly redefines shock absorption with military-grade technology.
Top-quality steel: Selected aviation-grade SUP9A special spring steel increases strength by 30% and offers toughness far exceeding industry standards.
Tempering: Vacuum quenching and precision tempering processes deliver an ultra-high yield strength of 1600 MPa, achieving zero failures in 200,000 fatigue tests, and extending lifespan by over 50% compared to standard parts.
Uncompromising accuracy: Fully automated laser testing ensures 100% accurate matching of stiffness coefficient and free height to original specifications, eliminating unwanted noise and associated damage.
Precision pre-assembled assembly of high-strength alloy supports, anti-loosening bolts, and cushions increases replacement efficiency by 40%.
18-month extended warranty—an industry-unprecedented commitment, backed by confidence in quality.
