 To Learn More:

By using traction pin,the semi-trailer can be connected to or seperated from tractor according to the requirement.
The trailer is mainly composed of frame,wagon box,traction device,braking device,axle assembly,electrical system,etc.

Frame:The frame is the main part for supporting load,mounting traction pin,suspensio and supporting device;
it's a space framework structure assembled by welding components such as H longitudinal beam(16Mn special steel
plate welded by using automatic submerged arc welding machine),through beam,horizontal beam and edge beam.
It's featured by its proper structure,balanced strength and stiffness ,high carrying capacity,permanent deformation-resistance,etc.

 

Fifth-Wheel
The fifth-Wheel is used to bear the front loading of trailer.The fifth wheel is divided into two kinds of 50#and
90# to match the traction pins of different specifications.

Supporting Device
It's a device to support the front loading of trailer after detaching.The support leg is divided into tandem-drive
form and single-drive form.With nearly identical structure,the two forms are both composed of base,lead-screw
driving mechanism,internal square cylinder,external square cylinder,gearbox,operating crank,etc.

Suspension
It's a bearing and damping device.
The suspension system is divided into two-axle of three-axle balanced steel-plate spring suspensions.The
steel-plate spring is fixed on the axle by using U-bolts with both ends stuck in the frame support and tandem
connection enabled by balance arm which will freely sway in a certain range to enable the balance of axle loading
in a certain range.The steel-plate spring mainly support the vertical gravity on the frame and the horizontal acting
force is transmitted by lower support and pull rod.
Through adjusting the pull rod,the two axles can be adjusted in parallel to avoid the exceptional abrasion to the tire.

Air Brake Assembly
With dual-line braking system,the trailer is mounted with an emergency relay value which is a device for the
normal driving braking and automatic emergency braking.

1.Air Charging and Safety Braking
When the air compressor is on, the air cylinder is charged through air-charging line via emergency relay value .
2.Service Brake
By stepping down the brake pedal,the compressed air will pass manipulation line and enter the control chamber
of emergency value to open the compressed air path and enable the air-charging of brake chamber and the brake
to work.By releasing the brake pedal,the brake is disable.
3.Emergency Braking
When the leading air pressure of air-charging line is below 392Kpa or the line is broken because the tractor accidentally
detaches from trailer on driving, the compressed air in the air cylinder will pass emergency relay valve and enter the brake
chamber to enable the brake to work and the trailer to aumotically brake.The quantity of emergency-storage
brake chamber shall not less than 2.

Axle Assembly
The axle assembly is the component used for bearing,driving and braking,which is mainly composed of tire,
wheel,wheel hub,brake and axle.

Electriacl System
The rated voltage for the electrical devices of the entire vehicle is 24V with signal-line circuit,minus earth.
The trailer is connected to tractor by using the cable with 7-pin socket.On the sides of trailer there are side signal
lights and side steering lights.At the rear,there are lighting and signal devices for driving, braking,reversing,
steering, fog light,license plate,etc.

Spare-tire Lift
The trailer manufactured by our company adopts the suspension-chain spare-tire lift.When using it,first lower
the chain of the spare-tire chain to the proper position,then mount the lift bracket on the center of the wheel rim,
twist the crank clockwise to enable the spare tire to rise via the chain and fasten the nut on the bracket when
reaching the required position.Reversely,twist the crank counter-clockwise and the spare tire will be laid down.

The OBT tipping semi trailer is high strength and durable that will be your best tool.
