Abstract: A winch control system for off-road mobile construction or forestry equipment that includes a designated cab or operator platform area for operating the off-road mobile construction or forestry equipment is disclosed herein, the winch control system may include an input device. The input device may include a control interface and may be configured to control one or more functions of a winch in response to user interaction with the control interface. The input device may be portable and may be configured to be moved about the designated cab or operator platform area. The winch control system may be configured to enable operation of the winch when the input device is positioned within the designated cab or operator platform area and such that the input device is unable to control the one or more functions of the winch from a location beyond the designated cab or operator platform area.

Abstract: A radial load measuring apparatus is disclosed, which may include a rotational member rotatably supported to rotate about an axis of rotation and configured to be subjected to a radial load, and at least one support member interfacing with the rotational member. Each support member may have a contact interface that is oriented at an oblique angle relative to a reference plane comprising the axis of rotation, such that the radial load applied to the rotational member is translated into a proportional axial force applied to the at least one support member in an axial direction. The radial load measuring apparatus may include a force sensor configured to measure the proportional axial force applied to the at least one support member from which to determine a magnitude of the radial load.

Abstract: A winch or a hoist (100) includes an input shaft, a rotatable drum (112), and a gearbox (120) including a plurality of high-contact ratio spur-type gears, the gearbox coupled to the input shaft and to the rotatable drum such that rotation of the input shaft at a first speed drives rotation of the rotatable drum at a second speed that is different than the first speed.
