ABSTRACT:
Conventional wheelbarrow are difficult to steer, particularly when fully loaded. The wheelbarrow of the present invention provides a simple solution to this problem. The wheelbarrow includes a pair of L-shaped axles carrying wheels (or skis for winter use) rotatably mounted in vertical sleeves on the frame of the wheelbarrow. A crossbar on the front end of a pair of handles carries a shaft rotatable in cylindrical bushings on the frame. A linkage connects the front end of the shaft to levers on the vertical arms of the axles, so that rotation of the handles results in rotation of the shaft and consequently rotation of the axles and wheels around the vertical axes of the vertical arms of the sleeves to steer the wheelbarrow.
