Abstract
A method of removing cutting bits from a milling work machine includes engaging a cutting bit connected to a rotary drum of the machine with a bit removal tool, actuating the bit removal tool to disconnect the bit from the machine, sensing a plurality of characteristics of removing the bit from the machine, and determining that the bit has been disconnected from the machine based on the sensed characteristics.
Claims27
A method of removing cutting bits from a work machine, the method comprising:
- engaging a cutting bit connected to a rotary drum of the machine with a bit removal tool;
- actuating the bit removal tool to disconnect the bit from the machine;
- sensing a plurality of characteristics of removing the bit from the machine;
- and
- determining that the bit has been disconnected from the machine based on the sensed characteristics.
2 more elements
A system for removing cutting bits from a work machine, the tool comprising:
- a bit removal tool comprising:
- movable bit removal structure configured to engage a cutting bit connected to the work machine;
- an actuator operatively connected and configured to displace the bit removal structure to remove the bit from the machine;
- and
- an encoder that senses a displacement distance of the actuator, the displacement distance of the actuator being indicative of a distance the bit removal structure is displaced by the actuator;
- and
- a controller communicatively connected to the encoder and configured to determine that the bit has been disconnected from the machine based at least on determining that the sensed displacement distance is greater than or equal to a threshold distance.
