ABSTRACT:
Apparatus for lifting a load through an arc includes two pivotally connected, overlapping housings which are pivoted relative to each other by a fluid operated piston disposed between the housings. The housings have overlapping sides provided with oppositely inclined cam tracks. Rollers driven by the piston and captured within the cam tracks transmit force between the sidewalls of the housings, thereby causing the housings to pivot relative to each other. One of the housings is adapted to have the load mounted thereon.
