KAROSERI DUMP TRUCK INDO karoseri

A standard dump truck is a truck chassis with a dump body mounted to the frame. The bed is raised by a hydraulic ram mounted under the front of the dumper body between the frames, and the back of the bed is hinged at the back to the truck. The tailgate can be configured to swing on hinges or it can be configured in the "High Lift Tailgate" format wherein pneumatic rams lift the gate open and up above the dump body. In the United States, a standard dump truck has one front axle, and one or more rear axles which typically have dual wheels on each side. Rear axles are either powered or unpowered. Most unpowered rear axles can be raised off the pavement, to minimize wear and tear when the truck is unloaded or lightly loaded, and lowered to become load-bearing when the truck needs the extra support. These are referred to as lift axles or drop axles. Lift axles can be steerable or non-steerable; steerable lift axles are always configured with single wheels on each side, instead of dual wheels. Lift axles positioned in front of the powered axles are called pushers; lift axles positioned behind the powered axles are called tags. A trailing tag is a special type of tag mounted on an arm that extends 12 to 15 ft (3.66 to 4.57 m) behind the truck frame to extend the overall outer bridge length of the vehicle. Common configurations for a standard dump truck include the six wheeler which has one powered rear axle, the ten wheeler with two powered rear axles, the tri-axle with one lift axle and two powered axles, and the quad with two lift axles and two powered axles.. The largest of the standard dump trucks is commonly called a "centipede" and has seven axles. The rear two axles are powered, the front axle is the steering axle, and the remaining four are lift axles. The intermediate axles are present to support the weigh over the length of the chassis and sometimes to provide additional braking power. In the European Union, the dump truck configurations are 2, 3 and 4 axles. The 4 axle eight wheeler has 2 axles at the front and 2 at the rear[notes 1] and is limited to 32 metric tons (35 short tons; 31 long tons) gross weight in most EU countries.[6]
