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.

Very large load haul dump trucks Used in mining have a huge diesel engine that turns a big generator. The electrical power from this goes to a big electric motor in each wheel.

Load boards help truckers connect loads that need to be shipped with truckers that need to haul loads. They are posted on the load board.
Some homophones for "hall" are haul, haw, and hal.
yes the dumper feels really bad by: tierra
because there is usually a butt load of stuff they have to haul as well as people on them
A dumper truck is used to carry and transport materials such as gravel, dirt and sand in construction. You can get more information about dumper trucks at the Wikipedia.

If the load you are talking about is weight not load to the engine. It will take more power to pull or haul. So RPM will go up while speed increases only marginally.
If it's something like a pickup or a van...no, it's okay to haul a load with a 30-day tag. There is a temporary base plate for big rigs which lasts 90 days. You can haul loads with it too.
