Abstract
A work machine may include a frame supported by a traction device and a power activated steering guide secured to the frame. The power activated steering guide may include a trunk portion arranged and configured to articulate laterally relative to a travel direction of the work machine. The trunk portion may include an actuation mechanism configured to perform articulation and a controller configured for controlling the actuation mechanism to articular the trunk portion to an offset dimension.
Claims18
A work machine, comprising:
- a frame supported by a traction device;
- and
- a power activated steering guide secured to the frame and extending forward from the work machine and laterally to provide a forward-looking operator with direct sightlines to the guide, the guide comprising:
- a trunk portion comprising an elongate element defining a longitudinal axis and being arranged such that the longitudinal axis extends laterally and transverse to a travel direction of the work machine, the elongate element being configured to articulate along the longitudinal axis and the trunk portion having an actuation mechanism configured to articulate the elongate element;
- a branch portion coupled at a first end to an external end segment of the trunk portion and extending therefrom to a second end, the branch portion configured to separately articulate between:
- a stored position;
- and
- a deployed position, wherein the second end is extended outwards from the stored position in the travel direction of the work machine;
- and
- a controller configured for controlling the actuation mechanism to articulate the elongate element to an offset dimension.
A method of adjusting a steering guide on a work machine, the steering guide having a trunk portion and a branch portion and extending forward from the work machine and laterally to provide a forward-looking operator with direct sightlines to the guide, the method comprising:
- receiving, at a controller, a command to adjust the steering guide to an offset dimension;
- controlling, with the controller, an actuation mechanism on the steering guide to move the steering guide from a stored position to a deployed position by:
- articulating an elongate element of the trunk portion of the steering guide laterally and transverse to a travel direction of the work machine, along a longitudinal axis of the elongate element, and until an external end thereof reaches the offset dimension;
- and
- articulating an elongate element of the branch portion of the steering guide such that the branch portion extends outwards from the trunk portion in a travel direction of the work machine.
