Product Description

What is rail rubber pad

Rail rubber pad (also called rail pad) is made of elastic polyurethane pad and is installed between steel rail and concrete sleeper. It is an important part of the supporting structure of heavy crane rail tracks and railway tracks.

The main functions of the rail pad are: 1. Buffer the high-speed vibration and impact generated by the vehicle passing the rail track 2. Protect the top of the concrete sleeper due to vibration and impact caused by fatigue cracking and wear, and protect the railway subgrade and rail sleeper 3. Let the railway signal system is electrically isolated

Detailed Product Information

Classification of rail rubber pads

Kingrail provides two types of rail pads, one is for continuous support rail and the other is for discontinuous support rail

Crane rail with rail pads installed, the slide rail can be kept safe when a small amount of movement and rotation. The pressure is evenly distributed between the crane wheel and the sliding rail and the contact surface.

When rail pads are installed on railway rails, the following two rail clip railway fastening systems are most commonly used: 1. For E rail clip railway fastening system 2. SK Rail clip railway fastening system

Features of rail rubber pad

The use of railway rubber pads can greatly improve the transportation capacity of motor vehicles, reduce the number of crossing repairs, and avoid traffic accidents caused by motor vehicles stalling. It has the following characteristics.

1. The raw materials of railway rubber pads are natural rubber, styrene butadiene rubber, neoprene, HDPE, EVA, high-density polyethylene, etc. The product has high elasticity and is not easy to deform or break under various temperatures. And it can be stable and not deformed under the pressure of more than 80 tons.

2. The service life of rail rubber pads is more than three times that of general pads, with long service life and low maintenance and replacement costs.

3. Complete models, suitable for laying of various rails such as 43kg/m, 50kg/m, 60kg/m, 75kg/m, wooden sleepers, concrete sleepers and other sleepers.

4. Pressure resistance, wear resistance, easy installation, firm contact with railroad, no impact and noise when vehicles pass, and good safety.
