MILLING MACHINE WITH A SYSTEM FOR DISABLING THE MILLING DRUM
A milling machine (20) for milling a roadway surface includes a frame (22) and a milling drum (32) that is mounted for rotation with respect to the frame (22). A primary drum drive assembly is operatively attached to the milling drum (32) and adapted to rotate the milling drum (32), and a ground-engaging drive assembly that is adapted to drive the milling machine (20) along the roadway surface. A lifting column (26) is attached at its upper end to the frame (22) and at its lower end to the ground-engaging drive assembly (24). The lifting column (26) includes a linear actuator which can be operated to raise and lower the frame (22) of the machine (20) with respect to the roadway surface. A sensor that is associated with the lifting column (26) is adapted to determine if the lifting column (26) is not supporting a portion of the weight of the milling machine (20) sufficient to insure that the milling drum (32) is not supporting any part of the weight of the milling machine (20). A controller (47) is operatively attached to the primary drum drive assembly and to the sensor. The controller (47) is adapted to receive from the sensor a signal indicating that the lifting column (26) is not supporting the portion of the weight of the milling machine (20) that is sufficient to insure that the milling drum (32) is not supporting any part of the weight of the milling machine (20), and upon receipt of such signal, to stop the rotation of the milling drum (32).
