This invention relates to coin-operated amusement games referred to as cranes. Cranes have a plurality of prizes that are distributed across the play field of a container that has a claw or other engagement device suspended above the prizes. A player remotely controls the location of the claw above the prizes to a desired location and the claw is then lowered toward the prizes. The play field surface on which the prizes are distributed can be vertically moved as the prizes are withdrawn to maintain the appearance that the container is substantially full of prizes. The drive mechanism that moves the play field surface includes a motor coupled to an drive belt that drives a threaded nut. As the nut is driven, opposite threads on a threaded rod are engaged and the rod is caused to move upward or downward. One end of the threaded rod is received in a bushing on the bottom surface of the play field surface. The invention also includes a motor for rotating the claw with respect to the play field surface and air powered claw device.
