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.

Radial load measuring apparatus

A mechanical overload sensor system for a planetary winch having a biasing means that when overcome by the force on a ring gear, opens an electric switch which terminates power to the winch.

Mechanical overload sensor system

An improved self-engaging clutch having a carrier plate with one or more clutch actuator fingers formed into the carrier plate.

Self-engaging clutch

A clutch mechanism () for use with a machine to disengage the machine until normal operation thereof is commenced. The clutch mechanism () includes a clutch engaging member () movable into engagement with a notch () of the ring gear () of a planetary gear stage () to engage the clutch, and movable out of engagement with the ring gear () to disengage the clutch mechanism (). The clutch engaging member () is spring biased to a position in which the clutch mechanism is engaged. A manually-operated handle () moves the clutch engaging member () via a link () and clutch actuator () from a clutch engaging position to a clutch disengaging position. An over-center position of the link () and clutch actuator () maintains the clutch in a disengaged condition, until normal operation of the machine is commenced, whereupon a protrusion () on the clutch actuator () is struck and the clutch actuator () is forced back to the engaged position, thus self engaging the clutch on commencement of normal machine operation.
