<p>A fluid-powered rotatable work platform assembly (14) for use with a vehicle (12) such as a vehicle (12) having an arm (30) for positioning the assembly (14). The assembly (14) includes a work platform or support configured to support a load, a body (64) having a cavity extending along a longitudinal axis, and an output shaft (74) rotatably disposed within the body generally coaxial with the longitudinal axis. A linear-to-rotary force transmitting member (96) is positioned within the cavity of the body (64) and engaged with the body (64) and the output shaft (74) to translate linear motion of the force transmitting member to rotational motion of one of the output shaft (74) and the body (64) relative to the other. The work platform (16) is coupled to one of the body (64) and the output shaft (74) with at least one link (46) and the arm (30) of the vehicle (12) is coupled to the other of the body (64) and the output shaft (74) so that when the output shaft (74) and the body (64) rotate relative to one another, the work platform (16) rotates relative to the arm (30) of the vehicle (12), while the pivoting link (46) allows the work platform (16) to sense the downward movement and/or an increasing load on the work platform (16).</p> |
