Abstract
A milling machine can include a frame; a rotor attached to the frame; vertically adjustable legs to raise and lower the rotor, each of the vertically adjustable legs with a track or wheel at a lower end to propel the milling machine; and a mechanism associated with at least one of the vertically adjustable legs to mechanically store and recall a leg height selected by an operator of the milling machine.
Claims18
A milling machine, comprising:
- a frame;
- a rotor attached to the frame;
- vertically adjustable legs to raise and lower the rotor, each of the vertically adjustable legs with a track or wheel at a lower end to propel the milling machine;
- and
- a mechanism associated with at least one of the vertically adjustable legs to mechanically store and recall a leg height selected by an operator of the milling machine, wherein the mechanism includes a sliding target configured to move in synch with a hydraulic cylinder located within the vertically adjustable leg, wherein the sliding target is coupled to a flexible cable which is operatively coupled to the hydraulic cylinder within the vertically adjustable leg.
A milling machine, comprising:
- a frame;
- a rotor attached to the frame;
- vertically adjustable legs to raise and lower the rotor, each of the vertically adjustable legs with a track or wheel at a lower end to propel the milling machine;
- and
- a mechanism associated with at least one of the vertically adjustable legs to mechanically store and recall a leg height selected by an operator of the milling machine, wherein the mechanism includes a sliding target configured to move in synch with a hydraulic cylinder of the vertically adjustable leg, wherein the mechanism includes a cable operatively coupled to the hydraulic cylinder within the vertically adjustable leg, wherein the hydraulic cylinder includes a cylinder rod and a collar is coupled to the cylinder rod, and wherein a mechanism rod is coupled at one end to the collar and at a second end to a first end of the cable.
A method for storing and recalling a height position of a vertically adjustable component of a milling machine, the method comprising:
- storing a height position of a vertically adjustable leg of the milling machine by moving a sliding target operatively coupled to a hydraulic cylinder of the vertically adjustable leg and setting a movable proximity sensor to a height of the sliding target to define a set point;
- and
- if the height position of the vertically adjustable leg has changed, recalling the set point by moving the hydraulic cylinder up or down until the sliding target reaches the level of the proximity sensor;
- wherein moving the sliding target includes using a cable operatively coupled to the hydraulic cylinder within the vertically adjustable leg to move the sliding target which is located adjacent the movable proximity sensor.
