ABSTRACT:
A vehicle display lift has a vertical mast containing a hoist mechanism which raises and lowers a movable carriage. A cantilever support member connected to the carriage extends outwardly from the mast and has a vehicle support frame on its outer end which receives and supports a vehicle. A low ramp allows the vehicle to be driven onto the support frame at ground level whereupon the hoist mechanism is activated so that the carriage is lifted and guided within the mast causing the vehicle support frame and vehicle to be elevated. The location of the vehicle on the pivotally attached vehicle support frame is such that the center of gravity is forward of the pivot thereby forcing the frame and vehicle to tilt forward as they are elevated until a predetermined tilt angle is achieved at which time the tilting action stops as the elevation continues. The elevation by the hoist mechanism continues until the carriage reaches the top of the vertical mast where activation of a limit switch by the carriage disables the raising circuit of the hoist control. A spring loaded safety latch engages the carriage as it nears the top of the mast as a precaution against failure of the hoist line and is disengaged by the lowering circuit. A sign secured at the upper portion of the vertical mast or on the carriage displays advertising information relative to the vehicle on display.
