Sisu Nemo is a hydraulic radial piston motor type developed and initially produced by Suomen Autoteollisuus (SAT). The system was patented in 1961. The motor produces a high torque at low speed and it has been primarily used to power both civil and military lorry trailers. A number of other applications have been designated for various ...
Typical applications for double acting telescopic cylinders include the packer-ejector cylinders in garbage trucks and transfer trailers, horizontal compactors, telescopic excavator shovels, and roll-on/roll-off trucks. In all of these applications, the cylinder operates near horizontally and thus gravity is not available to retract the actuator.
The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator. Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower (namely, water engines and water motors) but in today's terminology the name usually refers more specifically to motors that use hydraulic ...
Tiiger four-axle HMT module at Transporter Industry International headquarters in Haryana, India. A hydraulic modular trailer (HMT) is a special platform trailer unit which feature swing axles, hydraulic suspension, independently steerable axles, two or more axle rows, compatible to join two or more units longitudinally and laterally and uses power pack unit (PPU) to steer and adjust height.

A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.
Denison Hydraulics is a publicly traded U.S.-based company (Stock Symbol:DENHY) that manufactures industrial hydraulic fluid power systems (hydraulic pumps, motors, valves and engineered systems [1]) and components and is headquartered in Marysville, Ohio. Denison is owned by Parker Hannifin.
In order to further expand storage capacity, some trucks, typically called stinger units, are equipped with an "overhead" — an extra storage space mounted above the truck cabin which is accessible via the top ramp of a car carrier trailer. Up to 3 vehicles can be loaded on the truck: one on the roof, and two over the 5th wheel/drive tires. [3]
The first modular self-propelled trailers were built in the 1970s. In the early 1980s, heavy haulage company Mammoet [ 6 ] refined the concept into the form seen today. [ 7 ] They set the width of the modules at 2.44 m, so the modules would fit on an ISO container flatrack .
