Powertrans’ underground haulage systems can haul out of underground declines at significantly higher speeds than conventional underground haulers. Typical haul speeds up a 14% incline are 15 km/h, compared with 8 km/h by conventional haulers.
On arrival at the surface, a Powertrans underground system can haul any distance, at a sustained speed of 50 km/h, to a processing or stockpile area.
As with Powertrans surface haulage systems, all Powertrans underground systems use readily available off-highway light earthmoving tyres, which do not normally have the TKPH restrictions associated with large earthmoving tyres.

The Powertrans Powertruck™ and Powertrailer™ use proven, readily available components in an innovative way to provide mine owners, operators and transport contractors with a cost effective means of moving large volumes of material out of an underground mine than can be moved by traditional underground haulage systems.
Depending on mine requirements and operating conditions, up to two trailers can be towed by the Powertruck™. At least one of those trailers will be a Powertrailer™ using the same drive train as the truck and requires only a single operator.
Both truck and trailers use off the shelf driveline, suspension, axle and braking components. Off highway light earth moving tyres sizes are used due to availability.
Powertrans’ latest haulage system is its model, T1244 underground Mine Development Truck™.
This versatile truck is initially intended for use in material removal and infrastructure development during an underground mine’s development phase.
The T1244 is an economical alternative to underground articulated dump trucks, offering higher haul speeds (both up inclines and on the surface), reduced up-front capital cost and lower operating costs.
The Powertrailer™ utilises a 430Hp, six cylinder Detroit Deisel, turbo charged engine, which when combined with the Powertruck™, gives lots of power to pull up steep grades.
It has a traverse mounted cooling system, incorporating the radiator, charge air, and hydraulic cooling, which is controlled by the Engine Control Module.
The Powertrailer™ can be controlled from the cab of the truck
