    摘要： A hoist assembly for overhead lifting including an upwardly extending attachment member, a downwardly depending shank coupled to the attachment member and having a polygonal cross sectional shape, a hoist body coupled to the downwardly depending shank, and a plate positioned between the upwardly extending attachment member and the hoist body, that defines a first circular aperture that matingly receives the polygonal shank and a second polygonal aperture laterally spaced from the first circular aperture. The plate is moveable between a first position, in which the polygonal shank extends into the first circular aperture, and a second position, in which the polygonal shank extends into the second polygonal aperture. Rotation of the attachment member with respect to the plate is permitted when the plate is in the first position, and rotation of the attachment member with respect to the plate is inhibited when the plate is in the second position.

    摘要： A method of starting an engine with an engine starter that includes pressurizing a motor supply chamber with a fluid, selectively pressurizing an actuating chamber in response to the pressure in the motor supply chamber, moving a first valve along a first axis in response to pressure in the actuating chamber and moving a pinion toward engagement with the engine in response to movement of the first valve. The method further includes further pressurizing the actuating chamber, moving a second valve along a second axis in response to the further pressure in the actuating chamber, rotating the pinion in response to movement of the second valve, meshing pinion teeth with teeth on the engine, and starting the engine in response to rotation of the pinion.
