Core Functions and Roles

Pretensioning Fixing: Precisely applies pretension force, eliminates gaps in the connection, prevents loosening and displacement during equipment operation, and improves structural stability.

Load Adjustment: The pretension force can be adjusted in stages according to the working load to adapt to the load requirements under different working conditions and disperse stress concentration.

Structural Support: As the core support component of the connection, it bears the vibration and impact during equipment operation and protects the core components from damage.

Adaptive Connection: Precisely matches the equipment connection interface and can be used with seals and fasteners to improve overall connection reliability.

Suitable Scenarios

Primarily compatible with connection parts of construction machinery (excavators, loaders, etc.), widely used in mining, infrastructure, and agricultural machinery fields. Adapts to various connection scenarios requiring pre-tightening and fixing, serving as a fundamental auxiliary component for the normal operation of equipment.
