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.

An automatic load brake having a wear-induced locking mechanism for a hoist is disclosed. In various embodiments, the load brake includes a first shaft defining an annular hollow portion and a radially outer surface; a second shaft defining an engagement portion and a radially inner surface, the radially inner surface configured to engage the radially outer surface; a first reaction plate coupled to the first shaft; a second reaction plate coupled to the second shaft; and a plurality of friction discs, with at least one of the plurality of friction discs coupled to a cup and disposed between the first reaction plate and the second reaction plate, the annular hollow portion of the first shaft being configured to lock to the engagement portion of the second shaft upon thinning of the plurality of friction discs.

Automatic load brake having wear-induced locking mechanism

A self-adjusting automatic load brake for a hoist is disclosed. In various embodiments, the load brake includes a first shaft defining an annular hollow portion; a second shaft defining an engagement portion, the engagement portion configured for sliding disposition within the annular hollow portion; a first reaction plate coupled to the first shaft; a second reaction plate coupled to the second shaft; and a plurality of friction discs, with at least one of the plurality of friction discs coupled to a cup and disposed between the first reaction plate and the second reaction plate, the annular hollow portion of the first shaft and the engagement portion of the second shaft being sized and configured to accommodate thinning of the plurality of friction discs.

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 level wind mechanism includes a first screw and a second screw extending through a block. A shoe is disposed within the block between the first screw and the second screw. The shoe includes a first follower for engaging with and being driven by a thread of the first screw and a second follower for engaging with and being driven by a thread of the second screw. Each thread includes cams at the terminal ends of the thread for causing the shoe to disengage from that thread and to shift to engaging the other thread. In this way, the first screw and the second screw cause the shoe, and thus the block, to translate relative to the first screw and the second screw.

Automatic reversing screw mechanism for cable winding

The lifting assembly includes a cable end housing defining an inner cavity. The lifting assembly also includes a retainer ring disposed in the inner cavity at an end thereof. The lifting assembly further includes a cable retainer disposed in the inner cavity of the cable end housing and operative to retain a cable end fitting of a cable, the cable retainer extending from a first end to a second end and defining a helical slot extending from the first end to the second end to provide installation and removal access of the cable end fitting.

Helical slotted cable retainer for lifting assembly and method of assembling

A lifting assembly is provided. The lifting assembly includes a cable end housing defining an inner cavity. The lifting assembly also includes a retainer ring disposed in the inner cavity at an end thereof. The lifting assembly further includes a cable retainer disposed in the inner cavity of the cable end housing and operative to retain a cable end fitting of a cable, the cable retainer extending from a first end to a second end and defining a slot extending from the first end to the second end to provide installation and removal access of the cable end fitting, the slot having a first slot portion and a second slot portion that are angularly oriented relative to each other.
