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 pumps the hydraulic jack to raise the arm. To lower the arm, pressure is released from the hydraulic ...
In the above graphic, the four segments of the chain are labelled W, X, Y and Z. The magnitudes of their corresponding forces are F W, F X, F Y and F Z, respectively.. Assuming that the chain is massless, F X = 0 because segment X is not supporting any weight.
Diagram 3 shows three rope parts supporting the load W, which means the tension in the rope is W/3. Thus, the mechanical advantage is three-to-one. By adding a pulley to the fixed block of a gun tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff tackle.
Hydraulic hooklift hoists are mounted on heavy duty trucks to enable hauliers to change out flatbeds, dumpster bodies, and similar containers. Primarily used in conjunction with tilt frame bodies and specialised roller containers , generally designed for the transportation of materials in the waste , recycling , scrap and demolition industries ...

The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill.
