King Pin / Welding Type Fifth Wheel Plate Customization Thickness

Title: Customization Plate Thickness King Pin and Welding Type Trailer Fifth Wheel

Product application:

The king pin includes 50# and 90# .That is to say, its diameter respectively is 50mm and 90mm.

Trailers used for ordinary road transportation are usually equipped with 50.8mm traction pins, and 90mm traction pins are widely used in construction machinery transport trailers and special trailers. In addition to the corresponding trailer traction pin, the height is also not correct after the installation on the same tractor chassis. The height of the traction seat on the 50th is less than 90 when the vehicle is empty. The rear trailer is also lower in height and the vehicle stability is better.

Product specification

The fifth wheel includes single shaft type and double-shaft type.

Single shaft fifth wheel:

• It can only make a longitudinal tilt of about 80 around the Y axis. This type of traction seat has high driving stability and is suitable for high speed, light load and high center of gravity semi-trailers running on better roads. The disadvantage is that the frame is subjected to a large torque because it cannot swing laterally.

Double-shaft fifth wheel :

• It can make horizontal and vertical swings around the X and Y axes, which can protect the frame of heavy transport tractors under different road conditions. Usually, the two-axle type of traction seat has a large height and a single-axis type, and the lateral stability is poor during the high-speed turning of the vehicle, so this type of traction seat is less used in ordinary road transportation.
