摘要： The present disclosure provides an appliance for towing compact loads (e.g., logs), and include an auxiliary winch provided in combination with a main winch on a tractor without the need for separate powering means or the need to transport said auxiliary winch to the area adjacent to the load (away from the main winch/tractor.) The appliance may be provided by upgrading an existing tractor winch by, for example, attaching the auxiliary winch to a casing of the main winch, or to the ground adjacent the tractor with the main winch. The auxiliary winch may be furnished with a driving means powered by disposable powering means on the tractor that may include auxiliary pulley block(s) with an accompanying accessory to provide attachment thereof to the terrain, with each pulley block suitable for guiding an auxiliary cable in the area outside of the line between the main winch and the load.

摘要： 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.

摘要： 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.

摘要： A drive train is provided for hoisting gears, and in particular for hazardous transports. The drive train includes a drive motor (1), a cable drum (6) connected thereto, a reduction transmission (5) arranged between the drive motor (1) and the cable drum (6), a service brake (4) provided between the drive motor (1) and the reduction transmission (5) and a safety brake (7). To prevent damage to the reduction transmission (5) in the event of an emergency stop braking an automatic overrun disconnect means can be provided between the drive motor (1) and the service brake (4). The overrun disconnect means is preferably in the form of a freewheel (2).

摘要： Tension monitoring is described using a sensor which may exhibit an offset for which compensation may be provided to produce a zero voltage amplified output or to increase dynamic range. An arrangement determines whether a power reset is responsive to a battery bounce such that an initially-measured system start-up parameter can be retained. The start-up parameter is automatically saved at start-up if the power reset is responsive to a start-up from a shut-down condition. The start-up parameter may be a zero tension amplified output responsive to the sensor offset at zero tension. Protection of a tension data set is provided such that no opportunity for altering the data set is presented prior to transfer of the data set. A housing configuration forms part of an electrical power circuit for providing electrical power to an electronics package from a battery.
