Spring powered wheelbarrow

摘要

The present invention provides a spring powered wheelbarrow with a manually powered drive assembly. A foot crank winds a spring through a system of shafts and sprockets in a first direction. By releasing a brake upon a front wheel of a wheelbarrow, the wound spring transfers a rotational movement from a spring shaft to a freewheel sprocket adjacent to the front wheel, the rotational movement upon the front wheel assisting a user in pushing the wheelbarrow.
