Australian heavy-duty specialists from Doolan’s Heavy Haulage have relied on Scheuerle WideCombi axle lines to transport two crusher components. Two tractors, with a total tractive force of 500 tonnes and 14 WideCombi axle lines were required to haul a 160 tonne crusher component measuring 5.5 x 5.5 x 5.0 metres from engineering service provider RCR Tomlinson, based in Welshpool, Western Australia, to its final destination in a quarry. The two vehicle combinations were employed at the same time throughout.
The two heavy-duty combinations had to travel around 1,400 kilometres. 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 neither a police nor 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 2.5 kilometers 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 2.5 kilometres”, explained Ross Attwood from Doolan’s Heavy Haulage.
Doolan’s fleet of heavy load vehicles includes many axle lines from Scheuerle and has just ordered additional SPMT axle lines from the manufacturer.
