Overview

support gear, sorted

Engineered for crane counterweight and support gear transport, TRT B-Doubles help crews move more ancillary equipment safely and efficiently between sites. Available in skeletal and decked-in configurations, with purpose-built restraint, mounting and access systems, they help reduce load time, improve setup flow and keep crane operations moving.


Features

Crane support transport is never just about getting from A to B. Counterweights, jib sections, pads, timbers and support equipment all need to arrive secured, accessible and ready for efficient setup.

TRT B-Doubles are built around that reality, with configurations that help operators load smarter, travel legally and reduce the time spent preparing equipment on site.

  • B-Double Counterweight Configuration

    Built to move crane counterweights and support gear in a practical combination that helps reduce transport complexity.

  • Skeletal or Decked-In Build

    Choose the right deck format for your crane gear, tare requirements and loading preferences.

  • Purpose-Built Load Restraint

    Integrated bollards, headboards, rope rails and tie-down points help secure crane components with less workaround.

  • Safe Access Platforms

    Platforms, handrails and steps support safer access when tying down weights and checking the load.

  • Heavy-Duty Running Gear

    BPW suspension, disc-braked axles and EBS braking support dependable road performance.Side platforms, handrails and steps support safer access when tying down or checking counterweights on site.

  • Modular Mounting Options

    Mounting modules and specialised restraints help position components where they need to be for safer, more efficient loading.

Frequently Asked Questions

  • Can the trailer be configured for different crane support requirements?

    Yes. TRT offers standard and customisable trailer options, and can work from your load requirements, operating conditions and compliance needs to develop a fit-for-purpose solution.

  • How does a skeletal B-Double design help?

    A skeletal design removes unnecessary decking and keeps the structure focused around the loads being carried. For counterweight transport, this can support practical loading, restraint access and weight efficiency.

  • What load restraint features are included?

    Published TRT B-Double specifications include rope rails, tie-down points, counterweight bollards and mounting modules depending on configuration. These are designed to help position and secure heavy components safely.

  • Are B-Double trailer specifications the same in Australia and New Zealand?

    No. TRT’s published specification sheets note New Zealand specifications, with Australia and other countries available by request. Final specs should be confirmed for the operating market, route and payload.

  • What is a B-Train or B-Double trailer?

    A B-Train, also called a B-Double, is a two-trailer combination where the second trailer connects through a fifth-wheel coupling on the first trailer. It is used where operators need more carrying capacity and a stable, efficient trailer combination.

  • What is a TRT B-Train trailer designed to carry?

    TRT B-Train trailers are designed for specialised heavy transport tasks, including crane counterweights, jib sections and support equipment. The layout is built around safe loading, correct weight positioning and efficient crane support operations.

  • What is a TRT B-Train trailer designed to carry?

    Control is via remote or cab screen. This gives you flexibility in how you operate on site—whether you prefer control from the ground during positioning, or from the cab depending on your setup and workflow.


  • Are TRT B-Doubles available for Australian requirements?

    The supplied specs are shown for New Zealand, with TRT noting that Australian and other country specifications should be confirmed directly. TRT can work through the required design and compliance details for the operating region.
