ABSTRACT OF THE INVENTION A lifting apparatus includes two pairs of lift arms having respective displaced pivot points on a movable carriage for projecting such carriage towards a refuse- receiving container, and in an inverted position so as to dump the contents of a receptacle held on such carriage. The arms nest in a co-planar orientation when the carriage is in its fully lowered position, to minimize apparatus width. Various frame supports permit garbage truck and large trash container mounts, and fixed and mobile free-standing mounts. A particular hydraulic rotary motor having a relatively thin width may be used to power the apparatus, or drive other types of loads. The hydraulic rotary motor has meshed rack and pinion teeth generally enclosed within a cylinder immersed in hydraulic fluid passing therethrough to actuate a piston. The fluid lubricates the moving components for prolonging their service life with less maintenance. Plural cylinders may be aligned in parallel, and share a common pinion gear output shaft, with each cylinder having a reciprocating piston rod supporting rack teeth for engagement with such pinion gear.
