A dump truck, known also as a dumper truck or tipper truck, is used for taking dumps (such as sand, gravel, or demolition waste) for construction as well as coal. A typical dump truck is equipped with an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited ("dumped") on the ground behind the truck at the site of delivery. In the UK, Australia and India the term applies to off-road construction plant only, and the road vehicle is known as a tipper lorry (UK, India), tip-truck, tip-trailer, tipper truck, or tipper (Australia and New Zealand).The dump truck is thought to have been first conceived in the farms of late 19th century western Europe. Thornycroft developed a steam dust-cart in 1896 with a tipper mechanism.The first motorized dump trucks in the United States were developed by small equipment companies such as The Fruehauf Trailer Corporation, Galion Buggy Co. and Lauth-Juergens among many others around 1910. Hydraulic dump beds were introduced by Wood Hoist Co. shortly after. Such companies flourished during World War I due to massive wartime demand. August Fruehauf had obtained military contracts for his semi-trailer, invented in 1914 and later created the partner vehicle, the semi-truck for use in World War I. After the war, Fruehauf introduced hydraulics in his trailers. They offered hydraulic lift gates, hydraulic winches and a dump trailer for sales in the early 1920s. Fruehauf became the premier supplier of dump trailers and their famed "bathtub dump" was considered to be the best by heavy haulers, road and mining construction firms. Companies like Galion Buggy Co. continued to grow after the war by manufacturing a number of express bodies and some smaller dump bodies that could be easily installed on either stock or converted (heavy-duty suspension and drivetrain) Model T chassis prior to 1920. Galion and Wood Mfg. Co. built all of the dump bodies offered by Ford on their heavy-duty AA and BB chassis during the 1930s.Galion (now Galion Godwin Truck Body Co.) is the oldest known truck body manufacturer still in operation today. The first known Canadian dump truck was developed in Saint John, New Brunswick, when Robert T. Mawhinney attached a dump box to a flatbed truck in 1920. The lifting device was a winch attached to a cable that fed over sheave (pulley) mounted on a mast behind the cab. The cable was connected to the lower front end of the wooden dump box which was attached by a pivot at the back of the truck frame. The operator turned a crank to raise and lower the box.Today, virtually all dump trucks operate by hydraulics and they come in a variety of configurations each designed to accomplish a specific task in the construction material supply chain.A standard dump truck is a truck chassis with a dump body mounted to the frame. The bed is raised by a vertical hydraulic ram mounted under the front of the body, or a horizontal hydraulic ram and lever arrangement between the frame rails, and the back of the bed is hinged at the back of the truck. The tailgate can be configured to swing up on top hinges (and sometimes also to fold down on lower 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. Isuzu Motors Ltd. (Japanese: いすゞ自動車株式会社, Hepburn: Isuzu Jidōsha Kabushiki-Kaisha, TYO: 7202), trading as Isuzu (Japanese pronunciation: [isɨᵝzɨᵝ], /iˈsuːzuː/), is a Japanese commercial vehicle and diesel engine manufacturing company headquartered in Tokyo. Its principal activity is the production, marketing and sale of Isuzu commercial vehicles and diesel engines.It also has a number of subsidiaries, including Anadolu Isuzu (a Turkish joint venture with Anadolu Group), Sollers-Isuzu (a Russian joint venture with Sollers JSC), SML Isuzu (an Indian venture formerly known as Swaraj Mazda), Jiangxi Isuzu Motors (a Chinese joint venture with Jiangling Motors Company Group), Isuzu Astra Motor Indonesia, Isuzu Malaysia (Isuzu HICOM), Isuzu UK, Isuzu South Africa, Isuzu Philippines, Taiwan Isuzu Motors, Isuzu Vietnam, Isuzu Motors India and BYD Isuzu. Isuzu has assembly and manufacturing plants in Fujisawa which has been there since the company was founded under earlier names, as well as in the Tochigi and Hokkaidō prefectures. Isuzu-branded vehicles are sold in most commercial markets worldwide. Isuzu's primary market focus is on commercial diesel-powered truck, buses and construction, while their Japanese competitor Yanmar focuses on commercial-level powerplants and generators. By 2009, Isuzu had produced over 21 million diesel engines, which can be found in vehicles all over the world.Isuzu diesel engines are used by dozens of vehicle manufacturers, including General Motors. The name Isuzu translates into English as "fifty bells" (Wikipedia)
