The cart has a base frame having a top edge lying in a first plane and an inner mounting ledge lying in a second plane below said first plane. Wheels having stem members are mounted to assemble the base frame and to make it mobile. Cross members dimensioned to fit in the space between the first and second planes are releasably mounted on the main frame to permit their adjustment into general alignment below the support points of the load which is to be subsequently supported by the cart. A first locking device is provided to secure the cross members in position. Supports are mounted on each cross member for movement in a first direction parallel to the horizontal plane of the base frame and in a second generally vertical direction relative to the base frame. A second locking device is provided to secure each support in its selected position.
