Travelling 1,400km

Two tractors with a total tractive force of 500t and 14 WideCombi axle lines were required to haul the 160t crusher components measuring 5.5m x 5.5m x 5m from engineering service provider RCR Tomlinson, based in Welshpool, Western Australia, to their final destination in a quarry.

The two vehicle combinations were employed at the same time throughout. A large international logistics company commissioned the heavy goods professionals from Doolan’s Heavy Haulage to execute the task.

The two heavy-duty combinations had to travel around 1,400km, a route which featured a sufficient number of potential problems. However, due to the clever construction of the WideCombi axle lines, Doolan’s Heavy Haulage benefited from numerous advantages. Through the favourable distribution of the load weight on the axle lines and the relatively low dead weight as well as the low overall height of the transport vehicle, the two road trains were able to complete the majority of the route without either a police or power escort.

In addition, the convoy was able to drive throughout most of the daytime and did not have to switch to short time slots. The power escort only had to lift power lines on a total of 2.5km of the trip so that the two trucks could comfortably pass underneath.

“If we had used transport equipment from local manufacturers, additional axle lines would have been necessary to distribute the load correctly. Because of the additional height of the transport, we would have needed the support of a power supplier to drive under power lines for 250 instead of 2.5km”, said Ross Attwood from Doolan’s Heavy Haulage.
