A "fifth wheel coupling" is a device that connects the tractor with the trailer.
The mechanism is simple and can easily be removed.
As the only domestic coupler maker, we are open to all our customer requests,
and manufacture and market the fifth coupling load of 4t to 60t.
We have 50 years of achivements since Sohshin was still Kakuwa seiki(manufacturing
and marketing since January,1963),and with the trust we have built with other major
domestic manufacturers, we have reached 70% in the domestic marketing share.
Performs pitching and rolling(the control of front and rear,and sideway movements).
Suitable for heavyweight transportation on rough roads.
Also,when adjusting the movements with the adjusting wedge,
it can be used as a type 1 axis.
Because the position of the fifth wheel coupler is easily adjustable according to trailer,
there is no need to choose a trailer.
In addition,with the change of the offset position, the traction is able to drive with efficiency.
This results in an improvement in running performance and operational feel.
(The control of the fifth wheel coupling load according to the slide is required.)
The use of the vehicle you are now using is also possible. Please contact us for more information.
Because the coupling is adjustable due to the slide mechanism,
connection with various trailers is possible.
One vehicle can be used with multiple trailers and
this can contribute to the safety on rough or snow-coverd roads.
