Mechanical design for manufacturing

A stone quarry in a remote part of the world requires that stone blocks of 3 cubic feet in volume be moved up a 50 ft long ramp which is inclined at 30 degrees. Since the location is remote, the blocks must be moved usng human power. On a continuous basis, human power can sustain an output of 0.25 HP. The top of the ramp is even with the deck of the truck which will transport the blocks.

Design a system which will provide this function and state clearly how many blocks can be moved out of the quarry if the system is powered by a single worker.
