A height-adjustable cart is provided and includes an undercarriage having a wheeled frame, a double scissor-type lift mechanism and a support frame which is height-adjustable relative to the wheeled frame by the lift mechanism. The wheeled frame includes a pair of extendable rear wheel supports which are each pivotable between a retracted position and an extended position. While in the retracted position, the wheels are in close proximity to the frame, thereby defining a small cart "footprint" for compact storage. While in the extended position, the wheels extend transversely away from the frame, thereby widening the cart "footprint" for stability and for ease of transportation. The height-adjustable cart further includes a detachable table onto which heavy equipment may be loaded. The detachable table includes wheels suitable for carrying the weight of the equipment and for transporting the heavy equipment thereon separate from the undercarriage. The support frame is provided with a pair of rails which receive rollers of the detachable table for rolling the table onto and off from the undercarriage. A lock mechanism is provided in each rail to capture the respective roller therein and to prevent removal of the detachable table from the undercarriage until the locking mechanism has been released.
