250 Ton Multi Axle Modular Trailer for Sale in Vietnam - Shiyun Vehicle
These multi-axle trailers were customized by a Vietnamese customer, and Shiyun Vehicle completed the production within 20 days and tested the load. Today, the 10 axle modular trailer is packaged and shipped to Vietnam.
The multi axle modular trailer is provided with a drawing link to the forward section to make it possible for the trailer to be mounted pivotally to the towing vehicle. There is also the sub-chassis carrying the front pair of wheels and is able to turn in relation to the adjacent sub-chassis.
Other specifications include the need for a steering arm, a mounting that is movable with the use of the steering arm, a system of linkages that are connected in between each of the pivot points of the wheels and the said mounting.
The linkages should be operated to facilitate the turning of the first wheels due to the resulting turning motion of the front section of the trailer to allow the trailer to follow the towing unit.

The frame of multi axle trailer is the main component for bearing weight considering the most dangerous load condition.
In its scope, the main bearing parts of the modular unit are the main girder of the frame, the wheel bogie and several others. These adopt firm box-type beam structure made of high-performance welding plate material. The recommended material should have a yield strength of 690MPa. The whole frame which has strong strength and great ability to withstand bending moment can solve the problem of concentrated loading efficiently.
The surface of the main structure should be treated carefully through a sand blasting process. Again, the thickness of the painting used on the surface should meet the recommended national standards. Still, the brand of the painting used should be among the top brands in the world. All the small-sized parts of the frame should be zinc-plated.
The box-shaped center beam and the stable crossbeams give the frame a high degree of rigidity. Hence, the frame can achieve its optimal loading level. The steering system, air tank, and hydraulic oil tank are all integrated into the bogie frame. Thus, the parts are protected against damage and corrosion.
The frame has a reinforced loading deck, which allows extreme point loads. The optimized bolt-plate coupling, on the other hand, eliminates any problems that may arise when assembling the longitudinal combinations.

Steering System
The steering system of multi axle trailer is able to simultaneously and precisely effect the steering motion of the trailer wheels linked with over two axles. This is possible in a multi-axle vehicle to the point of producing the desired steering effects while keeping everything in balance.
In addition, the system works to allow the vertical oscillation of a single wheel of the motor vehicle by not causing the undue wear of tyres due to the steering geometry of the wheels.
This has been the issue especially in 250 ton multi axle trailer axle configurations where 3 or 4 of them need coordination to produce a simultaneous steering.
In the hydraulic control unit provided in the multi-axle trailer, various fluid sources are offered for various steering mechanisms so that hydraulic failures in either of the vehicle hydraulic system will not lead to simultaneous malfunctioning of the means of steering for the other wheels.

Steering Operations
The multi-axles trailer has many axles even up to 10 axles. So, the trailer’s axles need to be steered by either self-steering or automatic steering. Steering without wheels causes serious wearing.
In order to minimize the tear and wear on the tyres and the trailer chassis stress, it is advisable to let the multi axle trailer wheels to accurately follow the towing vehicle wheels regardless of whether it is on a tractor or a lorry.
For this to be achieved, it is normally important that successive wheel pairs take up slightly varying angles and positions under the trailer chassis. Conventional steering systems for trailers make use of the bogie system for steering through means where both the wheels of a pair get turned concurrently through the changing axle angle where the axle links up the wheels together. The trailer can get signal when gooseneck or drawbar steering, the axles will be controlled by PPU automatically, you can also use the remote control to steer all axles.
