Abstract
A control device configured to control a winch assembly having a supporting structure has a guide, which engages a cable extending along a path in a sliding manner, and is configured to follow the movements of the cable crosswise to the path; a first control chain activated by movements of the guide in a first direction crosswise to the path; and a second control chain activated by movements of the guide in a second direction crosswise to the first direction and the path.
Claims19
A crawler vehicle winch assembly control device comprising:
- a cable locator configured to position a cable of a winch assembly having a supporting structure;
- a guide configured to:
- engage the cable which extends along a path, and
- follow movements of the cable crosswise to the path;
- a first control chain activated by a movement of the guide in a first direction crosswise to the path;
- and
- a second control chain activated by a movement of the guide in a second direction crosswise to the first direction and crosswise to the path, wherein the second control chain is configured to stop, based on a position of the guide in the second direction and a threshold value of cable displacement in the second direction, at least one of:
- a winding of the cable and an unwinding of the cable by stopping a rotation of a powered reel.

A crawler vehicle winch assembly comprising:
- a supporting structure configured to mount on a crawler vehicle;
- a cable;
- a powered reel configured to selectively wind and unwind the cable;
- an idle sheave configured to support the cable;
- and
- a control device configured to control a position of the cable between the powered reel and the idle sheave, said control device including:
- a cable locator configured to position the cable;
- a guide configured to:
- engage the cable which extends along a path, and
- follow movements of the cable crosswise to the path;
- a first control chain activated by a movement of the guide in a first direction crosswise to the path;
- and
- a second control chain activated by a movement of the guide in a second direction crosswise to the first direction and crosswise to the path, wherein the second control chain is configured to stop, based on a position of the guide in the second direction and a threshold value of cable displacement in the second direction, at least one of:
- a winding of the cable and an unwinding of the cable by stopping a rotation of the powered reed.

A crawler vehicle winch assembly control device comprising:
- a cable locator configured to position a cable of a winch assembly having a supporting structure;
- a guide configured to:
- engage the cable which extends along a path, and
- follow movements of the cable crosswise to the path;
- a first control chain activated by a movemement of the guide in a first direction crosswise to the path;
- a second control chain including a sensor configured to detect a position of the guide in a second direction crosswise to the first direction and crosswise to the path, the second control chain activated by a movement of the guide in the second direction, wherein the second control chain is configured to stop, based on a position of the guide in the second direction and a threshold value, at least one of:
- a winding of the cable and an unwinding of the cable;
- and
- a shared rocker arm shared of the first control chain and the second control chain, the rocker arm including:
- a base configured to oscillate about a first axis with respect to the cable locator, and
- an appendix configured to oscillate with respect to the base about a second axis wherein the guide is supported by the appendix.
