High-Performance Rail Fasteners for 60kg/m Rail Tunnels DTVI-2 Iron Pads and Fasteners

Specifications

60kg/m rail

Product Introduction

DTVI-2 iron pads and fasteners for urban rail.

1. This fastener is elastic and split, suitable for 60kg/m rail tunnels, U-shaped structures and ground pillow-type integral roadbed sections.

2. The clamping parts are DI spring strips ($18), divided into two types: middle and joint. The gauge pads are divided into middle and joint gauge pads, each with four numbers: 6, 8, 10, and 12. Numbers 6 and 12 are for adjusting the gauge;

3. Technical indicators of fasteners:

(1) The pressure of a single spring strip in the middle is 8.25kN, and the elastic range is 10.5

(2) The pressure of a single spring strip at the joint is 8.5kN, and the elastic range is 9.5

(3) The vertical of the fastener node The static stiffness is 20~40kN/mm;

(4) The fastener can resist lateral fatigue load of 35kN and the load cycle is 3X106 times;

(5) The anti-climbing resistance of a set of fasteners is not less than 11.5kN;

(6) The pull-out resistance of the embedded nylon sleeve is greater than 60kN;

(7) The resistance value of the insulation parts of the fasteners is greater than 1082;

(8) The track gauge adjustment is +8, -12mm; the horizontal adjustment is generally 20mm.
