Abstract
A wheelbarrow is provided comprising a bed for receiving a load, with an axle mounted to the bed. First and second load-bearing wheels are rotatably mounted to the axle on opposite sides of the bed. First and second rotatable stabilizing wheels are mounted to first and second support arms, respectively, with each of the first and second support arms being rotatably mounted relative to the axle on opposite sides of the bed. A first locking mechanism is associated with at least one, and preferably each, of the first and second load-bearing to selectively permit or prevent rotation of the load-bearing wheels relative to the axle. A second locking mechanism is associated with at least one, and preferably each, of the first and second support arms to selectively permit or prevent rotation of the support arms relative to the axle. An actuator is provided for selectively locking and unlocking each of the first and second locking mechanisms.
