Widening Dolly

Increase payloads for 8 axle low loader by as much as 20t or more!

TRT's unique dolly design allows the 5th wheel to be positioned in the correct location for a 50/50 axle split.  This allows the drive tyres to reach maximum weight. In combination with a 4 Rows of 8 (4x8) low loader, a 66tonne payload can be achieved.

There are two 2x8 Dolly options:

  • Fixed width dolly
  • Widening dolly - up to 3.05m

Features include:

  • Sliding 5th wheel to maximise loading
  • TIDD walking beam suspension provides oscillation
  • Paint spec to match your fleet

View the drawings and specifications for each model below. If you're not sure which dolly is best for your operation, use our Trailer Selector table which shows the increased payload with different trailer options. If you are not sure,  get in touch with one of our team.

Widening Dolly

  • 2.5m to 4.2m
  • Sliding 5th wheel to maximise loading
  • TIDD walking beam suspension provides oscillation
  • 5400kg tare weight

Fabricated from high tensile steel to keep the tare weight to a minimum. Widens to 2.5m to 4.2m to achieve greater mass to comply with state laws whilst having the ability to close to legal 2.5m width for anytime travel. With sliding 5th wheel adjustment, load over the drives is maintained.

Fixed Width Dolly

  • Up to 3.05m
  • Tidd walking beam suspension
  • Sliding 5th wheel to maximise loading
  • 4300kg tare weight

Where widening the dolly has no payload benefits the fixed idth model at a lower tareweoight provides the solution. With TIDD walking beam suspension the rows of 8 axles are able to oscillate, providing stability with all tyres on the ground. Under 3.05m the dolly can be carried on trailer without having pilot assistance.
