Lift and dump capacities of hydraulic hooklift hoists typically range from 8,000 to 68,000 lb (3,630 to 30,800 kg). Generally a hoist is capable of lifting (off the ground) and dumping (onto the ground) the same maximum capacity, although there can be exceptions where short wheel bases are involved.
The first of these systems used mechanical clutches between luffing and hoist drums, giving simplicity and a "near level" result. [5] Later systems have used modern electronic controls and quickly reversible motors with good slow-speed control to the hoist winch motors, so as to give a positioning accuracy of inches.
The hydraulic pumps run constantly and actually use less energy than most chain lift drive motors. [1] An Accelerator Coaster's hydraulic launch system also provides constant acceleration, unlike the acceleration from electromagnetic linear induction motors which begins to decrease or trail off after the initial push.

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.
In the example above of the dump truck, the weight of the dump body, now raised at an angle of 60 degrees but empty of the load, must be enough to force the unpressurized hydraulic fluid out of the cylinder and cause it to retract to the fully collapsed position. [6] Spider lift set up outside a building.
Hydraulic cylinders; For the hydraulic fluid to do work, it must flow to the actuator and/or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types. Open center circuits use pumps that supply a continuous flow.
Hoist atop an elevator. A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.
A hydraulic hoist is generally made of an adjustable arm, hydraulic jack, frame, and a set of legs. The crane arm, with multiple lengths and weight capacities, has a hook on the end that connects a chain to the engine. The arm of the hydraulic engine hoist raises and lowers with the use of a hydraulic jack, which is operated with a bar that ...
