Abstract
A working machine includes a body, a telescopic working arm extendable via a first actuator, and a bucket pivotally mounted to the working arm and pivotable via a second actuator. The working machine also includes a first controller to control the first actuator and a second controller to control the second actuator, in the first mode of operation. In the second mode of operation, the second controller simultaneously controls the first actuator and the second actuator, and upon activation of the second mode of operation and actuation of the first and second actuators, the leading edge of the bucket moves in a direction away from the body of the machine.
Claims20
A working machine comprising:
- a body;
- a working arm connected to the body and configured to be telescopically extendable by a first actuator between a retracted position and an extended position;
- a bucket defining a leading edge and mounted to a distal end of the working arm so as to be pivotable about an axis orthogonal to an elongate axis of the working arm by a second actuator;
- a control system configured to activate first and second modes of operation;
- a first controller configured to control the first actuator in the first mode of operation;
- and
- a second controller configured to control the second actuator in the first mode of operation;
- wherein the control system is configured such that, in the second mode of operation, the second controller simultaneously controls the first actuator to extend the working arm and the second actuator to pivot the bucket in a direction towards a discharge position,
- wherein, upon activation of the second mode of operation and actuation of the first and second actuators, the leading edge of the bucket moves from a first position to a second position in a direction away from the body of the machine along a curved or arc-shaped path in which the leading edge moves in a forward direction relative to the body, and
- wherein the first actuator is extended when the leading edge is in both the first position and the second position.
