Sizing Dump trucks come in many different sizes and configurations for various applications. These trucks can be categorized by their capacity or the weight of load they can carry and by the number of axles. The smallest truck in production today is a 2 x 4 truck with a 10-ton capacity powered by a single axle while the longest truck is known as the centipede and has as many as 7 axles with a capacity of more than 50 tons. Dump Truck Types Small-sized trucks are designed to meet the required capacity limits for city driving as well as to maximize their maneuverability. In many countries a 10-wheeler truck with a maximum load of 30 tons is an acceptable capacity for driving on public roads. A commercial dump truck of this size is perfect for transporting loads onto construction sites within cities while keeping under the regulated load capacity.
Consider your average weigh hauling requirements. This means that you need to come up with an estimate of the average payload capacity that the truck will be carrying and transporting. This step involves identifying your gross vehicle weight rating (GVWR): an important factor in determining the size of your payloads. This important factor also has a direct bearing on choice of number and load capacities of the axles of the truck which should always stay within legal weight limits. Choose the best engine. Buying a dump truck that has more horsepower than you really need can just lead you to waste money. This is because you will be spending more money on fuel. If you will not be pushing GVWR limits choosing a truck that has a smaller engine may be the smartest option. In addition if you are operating on mostly flat jobsites and roads you dont really need to invest in a truck that has extra horsepower.
Side Discharge Safety Standard rear dump trucks have a number of safety issues of concern if not operated correctly. The two most significant concerns when using these vehicles is accidental contact with live overhead electric lines when the bed is raised and the possibility of a vehicle tipping when dumping an unbalanced load. Both of these concerns have been addressed and both can be avoided with the use of side discharge models making them ideal for non-standard use or in situations with less than ideal working environments such as working on uneven ground. Because the bed can lift up only as far as its width rather than its length the center of gravity rarely changes to the point where the truck tipping over sideways is an issue. Additionally since the bed only lifts as high as its width there is little chance of accidental contact with power lines.
With this vehicle the bed can be elevated by the use of hydraulics that allow the contents to pour from underneath the bottom of the unhinged tailgate. Rear dump trucks are well equipped to handle most jobs; however there are some situations where it is difficult to use this discharge version such as when working in tighter areas or with overhead power lines. Side dump models use a tilting base that is raised hydraulically from the side allowing for contents to be discharged from the vehicle without the bed reaching too tall of a height. These types are usually found on an articulating chassis; the dump bed is separate from the driver cab which is beneficial in a number of different ways.
