Abstract
A milling machine includes a primary drum drive assembly for its milling drum, and a ground-engaging drive assembly for driving the milling machine along a roadway. A lifting column is attached between the frame and the ground-engaging drive assembly. The lifting column includes a linear actuator which can raise and lower the frame of the machine with respect to the roadway. A sensor mounted to the lifting column is adapted to determine if the lifting column is not supporting at least a predetermined portion of the weight of the milling machine. A controller is operatively attached to the drive assemblies and to the sensor, and is adapted to receive from the sensor a signal indicating that the lifting column is not supporting the predetermined portion of the weight of the milling machine. Upon receipt of such signal, the controller will automatically control certain machine functions.
