ABSTRACT:
A portable vehicle engine handling hydraulic hoist including a wheeled base for mounting a vertically and swingable base boom with a tiltable and longitudinally movable horizontal boom pivoted to the upper end thereof. A nose pivoted to the outer end of the horizontal boom includes a shaft for carrying an engine supporting sling having spaced arms for bolting connection to the engine. A self-contained electric motor, hydraulic pump and oil reservoir are arranged on the base and connected by hydraulic lines to a control panel with control selectors adapted to be handled by the operator for selectively hydraulically actuating hydraulic cylinders in and connected to the booms and the horizontal boom nose and engine sling mounting shaft whereby an engine requiring repair may be readily disconnected from its motor mounts and transmission and so manipulated with precision and removed from a vehicle within the close confines of a stall in a repair shop and replaced when repaired or another engine installed.
