Applications

Construction and Civil Engineering

Earthmoving operations: Ideal for transporting excavated materials such as soil, sand, rock, and backfill, one of the most common and essential applications for dump trucks.
Aggregate transport: Efficiently moves sand, gravel, crushed stone, and other bulk construction materials to mixing plants or job sites.
Infrastructure projects: Supports major infrastructure developments such as roads, bridges, tunnels, dams, and airports by transporting various construction materials.
Construction waste removal: Transfers debris, rubble, and other construction waste from demolition or building sites to designated disposal facilities.

Mining and Quarrying

Ore hauling: Transports mined ore from open-pit or underground mines (using compact dump trucks for underground operations).
Overburden removal: Moves overburden material from the mining site to make way for ore extraction.
Waste Rock & yailings Transport: Hauls waste rock and tailings to dumping areas or tailings storage facilities.
