Boom Swing

From RitchieWiki

Mechanical Features and Designs

A boom swing is the extended arm component of an excavator or crane, used for both excavating and lifting, respectively. The boom swing is made operable with the use of either hydraulics or pneumatics, a system of fluids or compressed air that is pushed by pistons through a machine's hydraulic cylinder. This enables the boom to move in alternating directions and even swinging from side to side, in some configurations.[1]

While such machines have existed in their primitive forms for more than a hundred years, the boom component was not able to operate in a swinging fashion before the invention of hydraulics and pneumatics, both of which appeared and became widely used around the time of World War II.

Boom Swings are also referred to as articulated booms. Today, they are considered standard features on equipment. Because of the nature of the boom swing, earth can be excavated and items lifted in a very accurate and precise manner. Boom swing operation allows the operator to dig and lift materials with minimal effort and little, if any, realignment of the machine.
