    Abstract: A four-wheeled handcart used to transport a load under the control of an operator. The four-wheeled handcart is comprised of two main assemblies. The first assembly carries the load and the second assembly supports the load. The load is secured to the carrying assembly which is then tilted rearwards by the operator, using handles extending from the carrying assembly, until the carrying assembly is engaged by the supporting assembly. In this configuration the two assemblies are positively engaged to become an integrated unit which carries and supports the load thus enabling the operator to function solely as the pilot for the handcart.
