Powertrans produces a number of combinations for hauling material in surface mines. Currently, the products are side-tipping trailers of varying capacities to suit material densities and types.

Larger bins with stainless steel or other corrosion-resistant materials are used for coal, and smaller bins manufactured from high-quality steels such as Bisalloy and Hardox are offered where the hauled material is heavier and more abrasive. These trailers are used in road trains incorporating Powertrailers™.

Plans are well under way to introduce belly dump trailers in capacities and materials to suit the haul material. The supplementary power in road trains made up with belly dump trailers will be provided by a Powerdolly™. In these combinations, payloads ranging from 200 tonnes to more than 500 tonnes can be achieved.

Powertrans’ surface mining haulage systems offer a cost-effective alternative to conventional large rear dump trucks. Owning and operating costs of a Powertrans road train are significantly lower than large off-highway mining trucks because capital costs are about half the cost of larger units, as are maintenance costs.

All Powertrans units use readily available off-highway light earthmoving tyres. As a result, a Powertrans road train system allows speeds that are generally greater than can be achieved and/or sustained over haul distances by conventional off-highway mining trucks. Loaded speeds in the order of 55 km/h and unloaded speeds of 75 km/h are possible, depending on road condition and grades.

In mining applications with haul distances between 10 km and 50 km, a Powertrans-based haulage operation offers a viable low-cost and flexible alternative to rail or conveyor-based transport, with generally lower infrastructure costs. In addition, the deployment time to set up operations for a Powertrans road train system is usually far less than for conveyors or rail lines.

Pit Hauler: Powertrans’ most recent surface mining system is the Pit Hauler, which can haul up to 200 tonnes out of pits at higher speeds than conventional mining pits, and then for an unlimited distance to a processing, stockpile or ROM operation.

It eliminates the need to have one transport system to haul out of the pit, and a second system to transport from the pit exit to a stockpile. Loading options: Powertrans haulage systems are best suited to loading by wheel loader, rather than by excavator or shovel. Substantially lower loading heights typically mean that a Powertrans system can be easily and efficiently loaded by a wheel loader of at least one size smaller than what is required by a conventional large rear dump truck.
