[1] [better source needed] During World War II, the company provided nearly 75% of the Allies' earthmoving equipment. [2] In 1954, it built the first jack-up drilling rig.
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
The cam mechanism was further improved in 1925 by eliminating the drag chains for the shoes and changing to a cam wheel running in an oval track. This gave the shoe a proper elliptical motion. [ 6 ] [ 7 ] The first dragline using the new mechanism was the 3-W available in 1926.
A gantry crane has a hoist in a fixed machinery house or on a trolley that runs horizontally along rails, usually fitted on a single beam (mono-girder) or two beams (twin-girder). The crane frame is supported on a gantry system with equalized beams and wheels that run on the gantry rail, usually perpendicular to the trolley travel direction.

It had the same bore as the 171, but a longer stroke of 5 + 1 ⁄ 4 in (133 mm), giving it 37 horsepower (28 kW) at 2,000 rpm. Applications: 1918 Chevrolet Series FA (37 hp; 28 kW) [7]
