2x8 Dolly

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

Where widening the dolly has no payload benefits the fixed idth model at a lower tareweoight provides the solution.

Under 3.05m the dolly can be carried on trailer without having pilot assistance.
