Off-highway trucks are vehicles used to carry large quantities of materials (ore, earth or gravel) on construction site, mines or quarries. Different sorts of trucks may be found: off-highway trucks, articulated trucks, site dumpers, track dumpers or underground articulated trucks.
Off-highway trucks are the biggest models: they are used in quarries and open-air mines. They are known as robust equipment: for example, the Liebherr T282B and Cat 797F payloads may reach a few hundred tons. Articulated trucks are smaller but easier to handle. They may be driven on steep grounds thanks to their drive wheels (often 6×6). Articulated trucks have been developed in the 1960’s by Volvo and are used for road works, transport with quarries and earthmoving operations.
Track dumpers are mounted on a tracked undercarriage unlike other trucks which are equipped with wheels. They may be used on difficult grounds like quarries. Site dumpers, highly mobile, are able to carry hundreds kilos. Underground articulated trucks are used to underground grounds, mine galleries for instance. Therefore, their height is reduced.
The main attachment of an off-highway truck is its dumper, generally made with reinforced steel. Some tipper trucks, equipped with a reinforced dumper, may be used as an off-highway truck.
In old ways, off-highway trucks were used to carry farm commodities or garbage.
