An overview of CDH-C20 type railway buffer stopperCDH-C20 is a safety device installed at the end of the railway line to prevent vehicles from hitting the block when they slip away.CDH-C20 type is an improved model of CDH type, with reasonable structure and large braking force. The plug-in connection between the arm and the brake rail is simple to install and easy to repair and reset.

Technical specifications of CDH-C20 type railway buffer stopper

The total horizontal resistance of the railway buffer stopper is not less than 15 (T).

Allow the vehicle to collide with the vehicle at a speed of 20km/h.

The center of buffer rubber plate is 850±20mm away from the base rail.

The structure and working principle of CDH-C20 type railway buffer stopper

The buffer stopper is composed of the main frame and two pairs of booster, with a total length of 2800mm. It is composed of plate spring, spring seat, wedge iron and bearing seat, which is installed in the brake rail of the main body frame and the brake rail of the booster. Its function is to form the forward pressure when the brake is static, increase the friction resistance when braking, and can make the braking force continuously play a role in dynamic, until the stop. The support plate is made of the whole plate, which is composed of support, front and rear beams, upper and lower oblique beams, which are closely connected to form the main frame. The structure is reasonable, and the overall strength is large, which can withstand the impact of larger speed of vehicles. The arm plate is directly inserted into the brake rail by the lower shoe block, which is simple in structure and convenient in installation, maintenance and reset.
