Off-road dump truck
A dump truck is a truck used for transporting loose material (such as sand, gravel, or dirt) for construction. A typical dump truck is equipped with a hydraulically operated open-box bed hinged at the rear, the front of which can be lifted up to allow the contents to be deposited on the ground behind the truck at the site of delivery.
Off-road dump trucks more closely resemble heavy construction equipment or engineering vehicles than they do highway dump trucks. Off-road dump trucks are used strictly off-road for mining and heavy dirt hauling jobs. There are two primary forms: rigid frame and articulating frame.
The term ‘dump’ truck is not generally used by the mining industry, or by the manufacturers that build these machines.
Bottom dump normally describes a trailer that discharges its load by opening two clam shell doors under the load space. In some instances, one tractor may pull several trailers (road train).
Rear end/Rear dump trailers are especially effective for longer hauls (typically one mile or longer). Better tire load distribution resulting in increase in tire life. Savings in fuel, maintenance and operating costs. Short turning radius - highly maneuverable. Dump cylinders tip the body at a very high dump angle thus shedding the material in an efficient manner.
