A wheelbarrow includes a load carrying bin, a frame structure, a number of wheels, and a closed loop pivotal handle. The handle is attached near the rear of the wheelbarrow on a pivoting axis so that the user may adjust the height of the handle. The handle may be attached with two threaded pins having knobs at one end so a user may fix the handle at one particular height, may leave the handle entirely adjustable, or may remove the handle entirely for convenient storage of the device. The wheels are placed to provide complete support for the load and may include vertical swivel axes to make moving the wheelbarrow easier.
