The Diamond T 4-ton 6×6 truck was a heavy tactical truck built for the United States Army during World War II. Its G-number was G-509. Cargo models were designed to transport a 4-ton (3,600 kg) load over all terrain in all weather. There were also wrecker, dump, and other models. They were replaced by the M39 series 5-ton 6×6 trucks in the 1950s.
Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a ...
In 1964, the Payhauler 180 entered service. The 45-ton (43t) truck became the first large, all-wheel-drive end-dump truck in the market. In 1973, the original rear-drive model trucks were discontinued, and the all-wheel-drive truck models were designated the Payhauler 330 and 350 for their 45-ton (43t) and 50-ton (45t) trucks respectively.

The Fruehauf trailer company introduced revolutionary inventions to trucking and transportation with hydraulic dump trailers, bulk tanker trailers, and automatic fifth-wheel couplings among their more than one thousand patents, including the shipping container in 1956. Expanding across the country, Fruehauf had 16 plants and more than 80 ...
The original approach used by early European models, still widely used today, was a high pressure / low volume system. This setup suits chassis with space restraints, allowing for use of a smaller piston pump and a smaller hydraulic reservoir. Such systems operate between 4,000 to 5,800 psi (28,000 to 40,000 kPa).
