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.
