A hoist system may include an airframe, a cable disposed between the hoist assembly and a hook assembly, and a cable angle exceedance detection arrangement. The cable angle exceedance detection arrangement may include a housing comprising a first end and a second end, a payout disposed within the housing and comprising an aperture within an interior surface and disposed a first end and a second end of the payout, a detection member coupled to the housing, and a wiring assembly coupled to and disposed between the detection member and a controller, wherein the controller is coupled with a display assembly via a communication assembly.

Rescue hoist cable angle exceedance detection arrangement

A cable angle exceedance detection arrangement is provided. The cable angle exceedance detection arrangement may include a housing having an aperture extending therethrough defining an axis, the aperture being configured to allow a cable to extend through the housing from a first end of the housing, wherein the cable is aligned with the axis, to a second end of the housing. The cable angle exceedance detection arrangement may include a detection member coupled to the housing and configured to be contacted by the cable when a fleet angle defined between the axis and the cable at the second end of the housing exceeds a selected value.

A clutch assembly includes a first gear, a second gear, a first proximity sensor configured to determine a first number of teeth of the first gear that pass by the first proximity sensor within a period of time, and a second proximity sensor configured to determine a second number of teeth of the second gear that pass by the second proximity sensor within the period of time.

Clutch assembly for detecting and measuring slip using proximity sensors

A load sensing device for a rescue hoist includes a load pin mounted coaxially with a traction sheave. A cable extends from a cable drum and over the traction sheave before exiting the rescue hoist. The traction sheave is rotatably driven about a traction sheave axis to maintain a back tension on the portion of the cable extending between the cable drum and the traction sheave. When the cable is loaded, strain gauges in the load pin sense a strain on the load pin caused by the load, and the strain information is communicated to a load calculator. Entry angle information is also determined and communicated to the load calculator. The load calculator determines the load on the cable based on the strain information and the entry angle information.

Hoist cable load sensor

A hoist hook assembly having a cable overload detection system may include a plate, a hook mechanically coupled to the plate, and a switch mechanically coupled to the plate. The switch may be configured to translate into a triggered position in response to a load on the hook indicative of an overload condition.

Hoist cable overload detection systems and methods

A boom assembly for a hoist may include a flat surface configured to elastically deform in response to a load on the hoist, and a strain sensor coupled to the flat surface and configured to generate an electronic signal.
