A lightweight portable lift device for lifting and moving pinball games includes a generally H-shaped horizontal carriage including side beams interconnected intermediate the ends thereof by two closely-spaced crossbeams. Two vertical posts are respectively removably receivable between the crossbeams outboard of the side beams and supported by the carriage, each of said posts comprising telescoping tubes with the inner tubes having longitudinally spaced-apart apertures diametrically therethrough and having the upper ends thereof connected to a small platform engageable with the bottom of an associated pinball game. Jack mechanism is mounted on the crossbeams or on the posts and is coupled to the platform for raising and lowering thereof. Pins tethered to the device are receivable in the post apertures for locking the platform at any predetermined height and removing the load from the jack mechanism. The crossbeams may be pivotally connected to the side beams to provide a foldable carriage. The posts are dimensioned substantially to fill the space between the crossbeams to prevent accidental folding thereof in use. An auxiliary platform is mountable directly on the carriage for use thereof as a dolly.
