A fairlead for use with a winch is disclosed. The fairlead is made up of a first and second roller, a motor, a sensor, and a controller. The rollers are adapted to aid in spooling or unspooling a line. The motor drives at least the first roller. The sensor determines whether a winch drum is spooling or unspooling a line. The controller is connected to the motor and communicates with the sensor. The sensor determines whether the winch drum is spooling or unspooling the line. The controller is configured to direct the motor so that the rollers assist in unspooling or spooling the line in coordination with the winch drum. In some embodiments, the fairlead is integrated into the winch.

The invention relates to a motor-operated crane drive in which a more rapidly rotating motor (1) drives a more slowly rotating cable drum (3) via a transmission (3). A safety brake (5) is arranged on the more slowly rotating side of the transmission (2). A signal that is used for actuating the safety brake (5) is utilized for initiating an electrical deceleration of the motor (1).

A control system for a component of a rescue hoist attached to an aircraft is disclosed. In various embodiments, the control system includes a first bus extending between a control module of the rescue hoist and a control input device; a second bus extending between the control module of the rescue hoist and the control input device; and a hardwire extending between the control module of the rescue hoist and the control input device.

A cable angle detection assembly is provided. The cable angle detection assembly may include a housing defining an axis configured to allow a cable to pass partially through the housing such that a first portion of the cable is aligned with the axis. The cable angle detection assembly may include a bracket rotatably disposed within the housing. The cable angle detection assembly may include a guide element mounted to the bracket configured to guide the cable, when in tension, to be wrapped partially therearound thereby allowing a fleet angle to be defined between the first portion of the cable and a second portion of the cable that extends tangentially away from the guide element.

The present invention relates to an apparatus for recognizing the replacement state of a high-strength fiber rope for lifting gear such as cranes as well as to a lifting gear such as a crane in which such a high-strength fiber rope is installed. It is the underlying object of the present invention to provide an improved apparatus for determining the replacement state of a high-strength fiber rope and to provide improved lifting gear having such a fiber rope that avoid the disadvantages of the prior art and further develop the latter in an advantageous manner. To be able to more easily determine the respective degree of damage of the jacket and thus the closeness to the imminent replacement state of the rope, the apparatus is provided with a reference damage memory in which reference representations of the rope with different degrees of damage to the jacket of the rope are contained to allow for an optical comparison of an actual image of the rope with the stored reference representations and thus, determination of the replacement state.
