Abstract
A vehicle for transporting shopping trolley or carts. The vehicle has a tray for the loading of the shopping trolleys, and adapted for movement from a transportation position to a lower loading position in which trolleys can be easily loaded thereon. The tray maintains a substantially constant horizontal orientation through this movement. A tailgate or rear ramp is positioned at the rear of the tray and is movable between a ground engaging position and a raised position generally blocking the rear of the tray. A mechanical leverage mechanism lowers the ramp as the tray is being raised and raises the ramp as the tray is being raised between their respective upper and lower positions.
