Payloads vary depending on modular configuration

TRT has developed a new versatile modular platform trailer solution to be as flexible as your operations

The modular system allows the operator to add or remove modules from their TRT Platform trailer to suit the load being transported, without having to have a long trailer for every payload. Starting at the smaller 3 or 4 Line low loader it is easy increased to an 8 Line. Ask us about fitting a module to your existing TRT low loader!

The mounting system allows for safe and easy mount/dismount of Clip-On module with the ramps being able to connect on to the rear.  Some of the key features include:

  • Constructed using high tensile steel
  • Unique European angular contact spherical bearing in the steering system
  • Double acting hydraulic suspension
  • Hydraulic compensating Gooseneck
  • Electronic steering system

View the drawings and specifications for each model below. If you're not sure which trailer is best for your operation, use our Trailer Selector tool or get in touch with one of our team.

6 x 8 Modular Platform

  • Operates as 4x8 or 6x8 Platform
  • 1m closed , 4.4m open
  • Electronic Steering System, all axles steer.
  • 650mm of suspension travel
  • Hydraulic puller makes connecting Clip On easy

As a 4x8 this trailer with all axles steering and with 650mm of travel in the suspension makes for a very versatile and manoeuvrable trailer. With an easy to connect pin & bush system the 2x8 Clip On adds length and payload capacity for the extra big moves.

All axles steer via an Electronic Steering system, designed to have the axles steering at their optimum angle to suit the length or width of the trailer. Steering can be remote controlled for extra steer angle on tight corners or on site.


7 x 8 Modular Platform

  • Operates as a 3x8, 5x8 or 7x8
  • Operates as a split modular system for carrying bridge beams.
  • Electronic Steering System, all axles steer.
  • 650mm of suspension travel

Whether transporting earthmoving equipment of Bridge beams this Modular Platform meets the brief. Operating as either 3x8, 5x8 or 7x8 this unit will achieve your payload requirements without having to carry extra axles when not required.

With the Electronic Steering system all axles are able to steer, even when the trailer is transformed to carry Bridge beams with the rear 4x8 over 20m behind the front 3x8 trailer. Special Bolsters are mounted to the deck to secure the beams, with the rear trailer on remote control for the extra tight corners.

New - Electronic Steering System

For the ultimate manoeuvrability and control!

All axles are controlled through an electronic sensed steering system. Each axle will be controlled individually by a hydraulic ram that will ratio the correct steering angle in unison with all the trailers axles. 

The various trailers lengths are programmed into the system to optimize steering angles. In this mode, steering is controlled via the prime mover's 5th wheel with special wedge lock fitted. This electronic steering mode can also be manually overridden to allow the operator to power steer the trailer without using the signal from the prime mover's 5th wheel.

Axle Suspension

Axle and suspension

TIDD Double acting suspension provides 650mm of stroke for each axle group. Fitted with our unique European Angular Contact Spherical Bearing, for long life. Any axle group can be stored and lifted independently at the touch of a lever.

The axle with 300 x 150 Brake ensures optimum performance and extended lining life.

Axle lift

Axle lift

Any axle can be lifted independently with a simple touch of a lever. This can assist the operator when changing tyres, servicing or traveling over obstacles. The trailer can be manoeuvred into tight areas more easily with some axles lifted. 

Built for the heavy loads

Designed for the heavy loads

Constructed in Grade 80 Hi Tensile plate the extra deep coaming rail complete with doublers at each wheel cut out is built to minimize deflection. Plated in AR450 wear plate (1400mpa) over tje complete deck edge is welded to the coaming forming an 8mm lip. 

A formed coaming on the inside edge of the deck prevents buckling. A pre-camber is built into the Torsional Box Centre Spine, designed to be straight with 115tonne load over 5m length.

Fitted with a fully compensating hydraulic system, the TRT design Gooseneck allows the skid plate to move up and down automatically depending on the terrain.

Plumbed to an accumulator which takes all the shock and stress out of the complete combination in travel mode and allows constant weight on the drive axles during travel both On and Off Highway, achieving maximum traction.

It is supplied with a manual handle to adjust lift or lower the front of the trailer, due to deflection from the load, or to achieve more ground clearance on tight cambered terrain.


Positive steering

Two 6" High Capacity Double Acting Master Steer Rams at the skid plate linked to two 4" Slave Rams per side, ensuring positive steering. 

TRT Multi-Line Platforms are designed to steer both forwards and backwards when loaded to capacity. 

Ramp Module v2

Ramp module

Designed to accommodate either Additional Clip On Axle Rows or Ramp Modules. This photo shows the platform set up with a standard heavy duty ramp module. 

Manufactured from Grade 80 Hi-Tensile Steel, the standard ramps are Double Acting Hydraulic, single fold. Plated in AR450 Wear plate with cleats fitted full width. 

Welded at 400mm staggered centres to avoid grouser hang up. Profiled holes reduce wind drag. Standard ramp dimension are 1140mm wide by 3.0m long with the inside edge gusseted to load light weight equipment.

Suspension TRAVEL v2

Suspension Travel

The double acting suspension has 650m of travel. When travelling over undulating terrain with heavy loads it's important for stability that each wheel is on the ground. Each axle is hydraulically linked and load shares.
