ABSTRACT:
The machine for removing ferrous debris removes such debris from firing ranges where the removal of hard objects is desired to prevent ricochets during firing exercises, particularly on aircraft gunnery ranges. The machine includes a chassis towed behind a remotely controlled or automated vehicle, with a mechanism support frame pivotally mounted on the chassis. A series of magnetic operating arms is provided across the mechanism frame, with a chain drive conveyor cycling the operating arms as the machine is operated. The operating arms automatically release any gathered ferrous debris into a hopper as the arms reach the hopper during their cycle. A mechanism is provided to accommodate angular deflection of the operating arms relative to the hopper due to sloped terrain, and a further automated mechanism is provided to tilt and empty the hopper as required. No human operator is required in the immediate area of the machine.
