Title: Customization Plate Thickness King Pin and Welding Type
Trailer Fifth Wheel
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.
Max Payload: 50 - 90 T
material: Steel, 45# steel or 40cr
Product type: Bolted, Welding, Compaction King Pin
Size: 2" king pin, 3.5 inch king pin
2. Used for trailer, semi-trailer, truck trailer
3. High quality, Competitive price, Fast delivery
The Kingpin is the most critical component used in the load
transfer from semi-trailer.
Welding on a channel support for the 2 inch welded kingpin,must be
more than 110mm between welds.
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
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
