Bobcat Telescopic handler JLG telescopic handler A typical rotating telescopic handler Telescopic handler used for cooling tower construction. A telescopic handler, also called a lull, telehandler, teleporter, reach forklift, or zoom boom, is a machine widely used in agriculture and industry.
JLG is headquartered in McConnellsburg, Pennsylvania, United States. The company's products are used in various industries such as construction, fit-outs, industrial maintenance, material handling, and facilities maintenance. JLG was founded in 1969 and operated independently until its acquisition by Oshkosh Corporation in 2006.
Suspension is Oshkosh TAK-4 fully independent all-round, and by coil springs on the front two axles, hydraulic on the rear three. [5] The LVSR is based on a conventional C-section rigid chassis and to achieve the required turning radius, axles one, two, four, and five steer, the rear two axles steering mechanically and not electronically.

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.
However, many hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven. Also, a hydraulic motor is usually designed for working pressure at both sides of the motor, whereas most hydraulic pumps rely on low pressure provided from the reservoir at the input side and would leak fluid when abused as a motor.

A manifold is composed of assorted hydraulic valves connected to each other. It is the various combinations of states of these valves that allow complex control behaviour in a manifold. [ 1 ] [ citation needed ] A hydraulic manifold is a block of metal with flow paths drilled through it, connecting various ports. [ 2 ]
Badger had been formed in 1946 and developed a tractor-mounted hydraulic backhoe dubbed the "HOPTO" (Hydraulically Operated Power Take-Off) as it was driven by the tractor's power take-off. [17] The Company acquired in 1967, the Sargent Engineering Corporation of Fort Dodge, Iowa, a manufacturer of hydraulic cranes. Their six Sargent Hydra ...
A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring , a raised weight , or a compressed gas .
