摘要： A cable break-away device for a rescue hoist (12) connects a cable (16) to a cable drum (18) of the rescue hoist (12). The cable break-away device provides overload protection to the rescue hoist by disconnecting the cable (16) from the cable drum (18) when the loads transmitted through cable become excessive. The cable break-away device is configured to fracture, releasing the cable (16) from the cable drum (18), when the loads experienced by the cable break-away device exceed a predetermined failure set point. As such, the cable break-away device forms a mechanical fuse connecting the cable to the cable drum.

摘要： A hoist controller (18) for a rescue hoist (14) collects hoist operating data from one or more sensors during operation of the rescue hoist (14). The hoist controller (18) compares the hoist operating data to a maintenance parameter stored in a memory of the hoist controller (18) and determines a maintenance task status based on the comparison of the hoist operating data and the maintenance parameter. The hoist controller (18) automatically initiates maintenance routines where the maintenance task status indicates that maintenance is required, and the hoist controller (18) provides the maintenance routines to the user via a user interface. The hoist controller (18) can confirm that the maintenance task was successfully completed based on maintenance data received from the one or more sensors.

摘要： A drive train (22) for a rescue hoist includes a first stage (60), a second stage (62), and a third stage (64). The first stage receives an input from a motor and the third stage provides rotational power to a cable drum. The first stage, second stage, and third stage are disposed coaxially within a common housing. The first stage provides a first speed reduction, the second stage provides a second speed reduction, and the third stage provides a third speed reduction between the motor and the cable drum. The common housing includes a mounting flange for mounting the drive train to the rescue hoist.

摘要： A drive train (22) for a rescue hoist includes a mounting portion (30) for mounting the drive train within the rescue hoist. A load pin (34) extends through the mounting portion and into a static structure of the rescue hoist to secure the drive train to the rescue hoist. The load pin is configured to sense the strain generated when the drive train imparts torque to the cable drum (24) to rotate the cable drum. The sensed strain is communicated to a computer (36) configured to calculate a torque generated by the drive train based on the sensed strain and further configured to calculate the load on the cable based on the sensed strain.

摘要： A cable tensioning capstan assembly comprises a capstan drum (105) and at least a first traction flange (110). The capstan drum (105) may be configured to support a cable (e.g., a cable is configured to wrap around the capstan drum), and the capstan drum (105) may be configured to rotate about an output axis (52). The first traction flange (110) may be disposed adjacent the first axial end of the capstan drum and configured to rotate about the output axis (52). In various embodiments, the first traction flange (110) is independently rotatable relative to the capstan drum (105). A clutch assembly between an input shaft (51) and the first traction flange (110) may facilitate the independent rotatability of the first traction flange (110).

摘要： A level wind mechanism (28) includes a first screw (38a) and a second screw (38b) extending through a block (40). A shoe (48) is disposed within the block (40) between the first screw (38a) and the second screw (38b). The shoe (48) includes a first follower for engaging with and being driven by a thread of the first screw (38a) and a second follower for engaging with and being driven by a thread of the second screw (38b). 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 (38a) and the second screw (38b) cause the shoe (48), and thus the block (40), to translate relative to the first screw (38a) and the second screw (38b).
