Abstract: A load-handling apparatus usable for mounting missiles on an aircraft comprises a low wheeled support frame provided with braking and steering facilities, a pair of separate, side-by-side cranked support arms pivoted at one end on the support frame and hydraulically linked for synchronized vertical movement relative to the support frame about a horizontal axis, and load engaging structure at the other end of each support arm. Each cranked support arm is double cranked, so that, in a side elevation, it has a stretched, flat-bottomed V-configuration and the arms are movable about a common horizontal pivot axis on the support frame by an hydraulic actuator, whereby the hydraulic fluid serves to couple the support arms together for synchronized movements. The hydraulic actuator includes a master hydraulic cylinder connecting the support frame and one support arm and a sleeve hydraulic cylinder connecting the support frame and the other support arm.
