What is a load haul dumper?

Mining requires tough machines to remove and transport product out to processing centers. These machines are used in the tight confines associated with underground operations. At the center of the removal and loading operations is a tough-as-nails tractor with a scoop (called a bucket). Any one of this group of machines can be called a load haul dumper. The load haul dumper (LHD) used in mining must perform a primary operation that will support mining objectives - namely, getting material from the ground to the transport.

LHD's must pick up and carry heavy burdens safely, quickly and efficiently. They must have the power and flexibility to work hard, and must be engineered extremely well to allow them to do their job shift after shift, day in and day out. Efficiency must be built into them as well as energy costs continue to balloon. They must also provide long service for a fair capital cost, and allow a user an increase in his profit margin while working in an industry notorious for its low return on investment.
