    Abstract: A patient lifting decive has a pivotally mounted boom liftable by a hydraulic ram (14) which is extended by pumping hydraulic fluid from a reservoir (18) to a ram chamber (36) by means of a pump piston (32) reciprocable by a pump handle (28). For lowering of the boom the handle (28) is moved beyond the end of the suction stroke of the piston to depress a plunger (58) and open a return valve (48).

    Abstract: A hydraulically actuated locking device for a tilt cab vehicle having a latch pin rigidly connected to the cab or chassis and a latch assembly mounted on the chassis or cab. The latch assembly including a hook member positioned to engage the latch pin and a cam plate pivotally connected to the hook member, the cam plate having cam surfaces for initially providing linear and subsequently angular movement of the hook member to disengage the hook member from the latch pin, the movements of the cam plate being produced by a hydraulic ram which is positioned to engage the cam plate at a point offset from its pivot axis. The latch assembly also including a spring for cushioning shock loads on the cab, the hydraulic ram can be modified to provide a fluid pressure cushion on return motion of the cab.
