Kyle E. Grathwol - Sandusky OH, US

International Classification:

E21C 25/06
E21C 35/24

US Classification:

299 15

Abstract:

A milling machine adapted to remove milled material from a road. The milling machine may include a CAN based grade system operatively connected to a sensor and a milling drum, and a CAN Bus adapter operatively connected to the CAN based grade system. The milling machine may include a programmable logic controller operatively connected to the CAN Bus adapter. The milling drum selectively removes the milled material from the road, and the sensor provides a signal to the CAN based grade system, and the milling drum is positioned based on data from the CAN based grade system.

Abstract:

A working machine for conducting a roadworking operation includes a conveyor that is adapted to move roadworking material as a part of the roadworking operation. The working machine also includes a sensor which is adapted to determine if a condition exists that is indicative of the conveyor's operating under a load, and a controller which includes at least one timer. The controller is adapted to receive input information including a predetermined operating run-time for a wear part that is associated with the conveyor. The controller is also adapted to receive a signal from the sensor that a condition exists which is indicative of the conveyor's operating under load. The timer of the controller is adapted to use the signal received from the sensor to measure a period of time during which the conveyor is operating under load, and the controller is adapted to compare the measured period of time that the conveyor is operating under load with the predetermined operating run-time for the wear part. If the measured time matches the predetermined operating run-time, the controller will signal the operator that the wear part should be inspected for possible replacement, or should be replaced.
