Abstract:
A cutter head assembly for dismantling pallets includes a cross member pivotally supported on a machine. The cross member supports one or more cutter heads thereon in forwardly projecting operational position which is freely slidable in a lateral direction. The cutter heads have an offbearing tray for portions of the pallets. The assembly of cutter heads is tiltable rearwardly on the pivot support to an upper maintenance position. Lock pins hold the cutter head assembly positively between the down operational position and the up maintenance position. The center of gravity of the cutter head assembly is at the pivot support to provide a balanced structure, and a spring loaded member is provided to urge the assembly rotatably down to its operational position. The spring loaded member also maintains the cutter head assembly in its maintenance position. A positive lock is provided between the cutter head assembly and the machine frame in both of these positions.
