We have developed a product that will enable the operator to expand the trailer in the future to increase capability. Various axle modules can be added along with Chassis Insert sections WITHOUT compromising steering geometry.
This style of trailer that both widens and either extends in length are inherent for having the steering compromised in one configuration or the other. Other makes can only extend their trailers by adding Axle sets which often aren’t required but are used simply to get deck length. That’s where our Insert comes in. There is no need to spend hours or sometimes days (where multiple axle rows are coupled), to remove tie rods and reposition them to alter steering geometry.
TRT now have a proven product operating that fixes the above steering issue.
Our Modular Trailers are equipped with an electronic steering system. It can be set up by the operator from the controller in the Truck’s cab with the touch of a button (on the screen) to select the required configuration. Once selected the steering angle of all wheels will automatically change to the pre-programmed angles for that configuration whether it be width or length.
The Platform Modules are manufactured using Hi tensile steel and AR450 deck sheet (8mm), providing a strong yet flexible trailer, whilst minimizing the tare weight.
With a deep coaming rail, deepest in the industry at around 400mm with a special pressed return on the lower edge to add stiffness – Thickness of plate is 6mm grade 80, with an internal doubler of 10mm at each wheel arch. The Coaming rail is Plasma cut with a slight radius, which will allow the Decks to be fabricated with a positive camber. This method of construction produces a very stiff trailer with reduced deflection.
The rear Joint has an offset of inbuilt camber to assist with deflection when set up in its longest configuration (in the future).
The Platform trailer is designed using TRT’s Unique Swivel axle and double acting hydraulic suspension, allowing each axle to be steerable and to be lifted through 650mm of travel.
The trailer consists of 2 widening decks. The Gooseneck is TRT’s unique compensating Gooseneck. This feature will aid traction. The Gooseneck is “live” on and off highway and moves up and down with the terrain allowing constant load into the Drive or dolly.
Gooseneck length is designed for Dolly hook up.
TRT’s unique Quick Connect joint. Now using 2 Double acting Hydraulic cylinders combined with the Friction fit top coupling system at each joint. Coupled to the ESS steering system (Innovation Patent # 201802100) the trailers steering is reconfigured at the touch of a button to have the combination on the road in under 30 mins between joints.
