Abstract
Abstract A ruggedly constructed work cart particularly suitable for use by mechanics includes a center work platform which is selectively heightwise adjustable. A series of platforms positionable at different heights allow the cart to function as a ladder, while a removable handle is provided so that the cart can be positioned beneath a vehicle for the purpose of supporting heavy parts. A removable tool tray can be alternatively attached to a vehicle`s bumper or tire to provide a mechanic with a "step" to gain better access to a vehicle's engine compartment.
