Abstract
A system and method for a load-facing winch are described for hauling or lifting loads at least 30° from center of the primary support object. The load-facing winch includes a winch-mount that includes a housing, a center-pivot, a mounting-plate, and a plurality of springs. The mounting-plate is attached to the winch and tilts and/or turns about the center-pivot, which allows the winch to face the load. By directing the winch to face the load, angular resistance against a moving fairlead may be reduced.
Claims17
A winch comprising:
- a motor;
- a rotatable drum for winding a line;
- wherein the rotatable drum is connected to the motor;
- a winch-line-guide for positioning the line during winding, comprising:
- an elongated rod extending longitudinally within a frame for the rotatable drum and in substantially parallel relation to the axis of rotation of the drum,
- a fairlead through which the line penetrates,
- wherein the fairlead is connected to the rod, and
- wherein the fairlead is movable along the length of the rod;
- a winch-mount comprising:
- a housing;
- wherein the housing is attached to a primary support object;
- a center-pivot;
- wherein the center-pivot is attached to the housing;
- wherein the axis of rotation of the center-pivot is perpendicular to the axis of rotation of the drum, and the axis of rotation of the center-pivot passes through the drum;
- a mounting-plate to which the rotatable drum is attached;
- wherein the mounting-plate is rotatably connected to the center-pivot;
- a plurality of springs each attached at one end to the housing and at the other end to the mounting-plate for biasing rotation of the mounting plate about the center-pivot;
- and
- wherein, when the fairlead is unable to move along the length of the guide rod due to a force of a load working against a movement direction of the fairlead, the winch and mounting plate rotate about the center-pivot such that the force of the load is relieved, and the fairlead is able to move along the length of the guide rod.
