Technical characteristics

Elastic clamping

DI elastic clamp (φ18) is adopted, which is divided into middle clamp and joint clamp, and gauge pad of middle and joint.
The buckle pressure of a single spring clamp at the joint is 8.5kN, and the spring stroke is 9.5mm; The single spring clamp in the middle has a buckle pressure of 8.25kN and a spring stroke of 10.5mm.

Stiffness and resistance

The vertical static stiffness of the joint is 20-40kN/mm.
The climbing resistance of a set of fasteners is ≥11.5kN.
The pulling resistance of the embedded nylon sleeve is ≥60kN.

Electrical insulation

The resistance value of the insulation part of the fastener is greater than 108Ω.

Fatigue and adjustment

The system can resist the transverse fatigue load of 35kN, and the load cycle is 3×10^6 times.
The gauge adjustment is +8, -12mm; The horizontal adjustment is generally 20mm.
