Not every job fits a standard trailer. TRT designs and builds specialised trailer solutions around the load, the route, the site and the way you work.
From bookends and push-pull rams to winch tractor set-ups, tank mounts, bolsters and cab-operated hydraulic systems, we engineer the trailer around the challenge.
Built around the load. Engineered for the job.
A specialised trailer build starts with understanding what needs to move, where it needs to go, and what stands in the way.
TRT works through the key details before recommending a trailer configuration - payload, dimensions, support points, site access, route conditions, loading method, truck compatibility and future use. The result is a trailer solution designed for the real job, not just the spec sheet.
Specialised trailer build options
-
Bookends
Bookends are used for long, high or self-supporting loads that need to be carried from specific support points rather than across a full deck.
TRT can engineer trailer bookends for specialist heavy haulage applications, helping support long or awkward loads while keeping the trailer configuration practical for the route, site and payload.
Typical applications:
Long beams, structural components, energy infrastructure, large fabricated loads and project cargo. -
Push-Pull Rams
Push-pull rams help control trailer and truck movement in difficult access conditions. They are especially useful where traction, gradient, surface conditions or tight positioning make standard movement harder.
TRT can integrate hydraulic push-pull ram systems into trailer builds to assist with controlled pushing, pulling and positioning on challenging sites.
Typical applications:
House trailers, steep sites, boggy ground, tight access, controlled positioning and low-traction environments. -
Winch Tractor Set-Ups
Some loads need controlled loading, unloading or positioning support from the tractor unit as well as the trailer.
TRT can design trailer systems to work with winch tractor set-ups, helping support specialist heavy haulage work where equipment, machinery or non-powered loads need to be pulled, positioned or recovered with greater control.
Typical applications:
Plant, machinery, site equipment, non-powered loads, recovery support and specialist loading conditions. -
Tank Mounts
Tank mounts are designed to support cylindrical or rounded loads safely and efficiently. TRT can engineer custom tank mounts, vessel supports, cradles and mounting systems to suit the shape, weight and support requirements of the load.
Typical applications:
Tanks, vessels, silos, pipes, drums, pressure vessels and cylindrical industrial components. -
Bolsters and Load Support Structures
Bolsters and custom support structures help carry loads that need more than a flat deck. TRT can engineer bolsters, cradles, frames, posts, pockets and mounting points to suit the load and the way it needs to travel.
These systems are designed around the interface between the trailer and the payload, helping support the load correctly from pick-up to delivery.
Typical applications:
Beam transport, project cargo, counterweights, equipment modules, long loads and purpose-built transport systems. -
Hydraulic and Cab-Operated Systems
Specialised trailer builds often need powered functions that make the job safer, faster and easier to control.
TRT can design hydraulic and cab-operated trailer systems for functions such as lifting, lowering, tipping, tarpaulins, controlled movement, steering support and remote or in-cab operation.
Typical applications:
Side-tipping trailer systems, powered trailer functions, multi-trailer control, hard-to-access sites and specialist operating requirements.

Got a job in mind?
Bring us the tricky loads, tight sites and hard-to-solve transport problems.
We’ll help make the right trailer solution possible.
From proven platforms to custom engineering
Some specialised builds start with a proven TRT platform. Others are engineered from the ground up.
TRT can build from existing solutions including ESS Modular Platform Trailers, Rows of 8, Deck Wideners, Full Wideners, Dollies, B-Trains / B-Doubles, Crane Equipment Trailers, Counterweight Skeletal Trailers and Boom Dollies.
We’ll help choose the right starting point, then configure it around your load, route, site and operation.

Frequently Asked Questions
-
What is the difference between a B-train and a B-double?
B-train and B-double are closely related terms. In New Zealand, B-train is commonly used. In Australia, B-double is the more common term. Both describe a prime mover towing two semi-trailers connected through fifth wheel couplings
-
Does TRT build jinkers?
For long-load support, TRT can configure ESS Modular Platform Trailers with bolster systems to achieve the required support, capacity and manoeuvrability for transporting long loads.
-
What are trailer bookends?
Trailer bookends are support structures used for long, high or self-supporting loads that need to be carried from specific support points, rather than across a full trailer deck. They are often used for specialist heavy-haulage applications where the load shape, height or length needs a custom support solution.
-
What are push-pull rams used for?
Push-pull rams are hydraulic systems that help control trailer and truck movement in difficult access conditions. They can assist with pushing, pulling and positioning where the site is steep, tight, boggy or low on traction.
-
Can TRT build trailer tank mounts?
Yes. TRT can engineer tank mounts, vessel supports, cradles and custom mounting systems for tanks, silos, pressure vessels, pipes and other cylindrical loads.
-
What is a winch tractor set-up?
A winch tractor set-up uses a tractor unit with winching capability to help pull, position, load or recover heavy equipment and specialist loads. TRT can design trailer systems to work with winch tractor set-ups where controlled movement is required.
-
Can a specialised trailer build start from an existing TRT trailer platform?
Yes. Some specialised builds start with proven TRT platforms such as ESS Modular Platform Trailers, Rows of 8 Trailers, Deck Wideners, Full Wideners, Dollies, B-Trains / B-Doubles, Crane Equipment Trailers, Counterweight Skeletal Trailers, Boom Dollies or House Trailers. Other builds are engineered from the ground up.
-
What industries use specialised trailer builds?
Specialised trailer builds are used across freight and transport, construction and infrastructure, defence, energy, agriculture, forestry and mining. They are designed for loads, routes and operating environments where standard trailer configurations are not enough.
