- the compensation devices in question here are preferably used where a load lifting or lowering operation of a load attached to a load rope is to be carried out by means of a conventional rope hoist.
- the pertinent load or material transport is naturally exposed to interference, as may arise, for example, from increased wind loads, increased waves or other interference such as bumps or the like, during operation of the respective hoist, in addition to a stationary installation, for example as part of a port crane , as well Machine part of a movable machine or as part of a transport ship is regularly moved.
- the respective hoisting hoist is equipped with a winch of conventional design, which has a rotatable drive for winding and unwinding of the rope a controllable in reversing electric or hydraulic motor. If it comes to a superposition of the described conventional lifting operation along predetermined target positions of the load due to the interference described above, for example, because a equipped with the cable hoist transport ship is exposed to a more or less strong swell, would without the known balancing device via the rope
- the load attached to the hoisting hoist in each case follows the swell quickly, taking actual positions deviating from the setpoint positions, and could, for example, be damaged when settling on a solid ground, such as a quay wall or the seabed.
- the effective cable length is shortened or lengthened by means of the compensating device, as required in the form of a hydraulic working cylinder, on whose free piston rod end a guide roller is rotatably guided, over which the cable from the winch Coming goes.
- the piston rod unit By extending or retracting the piston rod unit, the effective cable length can be extended or shortened, so that a compensation of the described disturbing influences is possible.
- the rope is exposed to increased frictional wear at least in the area of the movement roller, which is moving for the compensation process, about which the rope is deflected. Since a large amount of time is required for the respective balancing on and off operation of the working cylinder controlled by its hydraulic system, also due to the large quantities of fluid to be moved, the known solution is not suitable for promptly performing balancing operations on the effective cable length. and functional safety as well as the position accuracy impaired. Due to the dimensions and the operating weight and the mode of operation, the known compensating device is basically suitable only for use in large equipment. Existing systems or machine parts can not be retrofitted with such a compensation device at reasonable cost. Based on this prior art, the present invention seeks to provide a contrast improved compensation device, with which can be avoided the disadvantages described above.

By a correspondingly large diameter wind rope friction can also be reduced in order to minimize such wear phenomena, especially on the rope.
- the hydraulic motor is directly controllable via the respective pressure chambers of the actuator and due to its direct coupling with the winch, the required balancing operations on the rope can be make delay, which increases the operational and functional safety and position accuracy of the balancing device according to the invention.
- the drive part of the actuating device can be actuated by means of at least one actuator.
- the at least two mutually separated pressure chambers of the actuating device are respectively fluidly connected to the respective hydraulic motor such that the one or the other pressure chamber serves to drive the respective hydraulic motor in one or the other direction of rotation, and that each of the drive of the respective Hydromotors except pressure chamber receives the displaced in its drive fluid for a subsequent dispensing operation.
- the functional division of the actuator into a drive part for the drive of the hydraulic motor and an actuator for driving the drive part allows the use of various technical solutions for the design and layout of the actuator.
- this in addition to a preferred embodiment of the actuator in the manner of a hydraulically actuable working cylinder, this can also be formed by an electric or hydraulic motor which actuates a spindle drive.
- control device has at least one valve device, which can be acted upon by a supply pressure of a supply unit to actuate the actuator in opposite directions of movement.

- the sensor device has at least one gyro and / or inertia-based sensor and / or a satellite-supported navigation device.
- sensors and devices are available relatively inexpensively and yet work sufficiently precisely to be able to reliably determine the respective load position.
- sensor devices are also already present on site, for example on board a transport ship, in order to monitor its position and position so that these can additionally be used for determining the position of the load attached to the cable relative to the respective means of transport.
- the drive part and the actuator each have at least one guided in a common housing of the actuator piston, and that the respective adjacent piston via a coupling device in operative connection with each other.
- a spatially separated arrangement of the drive part of the actuating device for driving the hydraulic motor of the actuator for actuating and driving this drive part which may be, for example, via a hydraulic coupling device in operative connection with each other, but these can preferably summarized in a common actuator housing in a space-saving manner be housed.
- the coupling is then preferably mechanically via a common piston rod unit.

In this way, the amount of fluid used for use and the pressure for the pressure chambers of the actuating device can be corrected, so that the hydraulic components for the cable winch drive can be supplied with sufficient fluid even during the dynamic reversing operation.
- the actuating device has a position detection device with which the position of the actuator and / or the drive part can be detected, and in that the control device controls the respective actuator taking into account this position by means of a computer unit. Because the position of the piston rod unit of the actuating device can be detected by means of the detection device, the control device and assigned computing unit can promptly record the actual position of the piston rod unit and control it for a control process for correcting the load-actual position in the direction of the respective predetermined load. Use target position.
- the respective hydraulic motor can be driven or braked in the two opposite directions of rotation, superimposed on the pressurization of the respective pressure chamber of the drive part by a hydraulic drive and brake unit.
- a hydraulic drive and brake unit of the predominant load lifting and Lastabsetzvorgang by means of winch feasible, and then additionally existing hydraulic motor is used exclusively to make the necessary compensation operations to comply with the load target position.
- the hydraulic motor can be dimensioned correspondingly small and requires only small amounts of fluid for the compensation reversing operation of the winch. It follows that then also the Betuschistsseinrich- device with its drive part and their pressure chambers with different Pressure levels only need to provide low fluid feed levels in order to take effect. To operate balancing hydraulic motor.
