An operating device includes a crane controller for controlling actuators of the loading crane and for generating sensor data based on the sensor signals, and an input device spatially separated from the crane controller for inputting control commands for the crane controller. The crane controller has a first telecommunications device for exchanging data signals with the input device, and the data signals output by the crane controller include sensor data. The input device has a second telecommunications device for exchanging data signals including control commands with the first telecommunications device. The input device has a transmitter device for outputting data signals. A signaling device is spatially separated from the input device, and has a receiver device for receiving data signals output by the transmitter device and a display device for displaying audio data and/or image data. The signaling device signals the audio data and/or image data to a user.

A mobile working machine comprising: a chassis (5); stabilizer legs (10) connected to the chassis; a hydraulic crane (20) carried by the chassis and comprising a crane boom (25) articulately connected to a rotatable column (22) and a lifting cylinder (26) for pivoting this crane boom; and an electronic control device configured to establish a maximum allowed working pressure for the lifting cylinder while taking into account the contribution to the stability of the mobile working machine against tipping from each stabilizer leg (10) that is in an active supporting position.

The electronic control device prevents a manoeuvring of a stabilizer leg away from the active supporting position if the working pressure of the lifting cylinder is higher than a threshold value corresponding to the value of the maximum allowed working pressure for the lifting cylinder that would ensue in case the stabilizer leg is made to leave the active supporting position.

Disclosed herein is a controller of a hoist. The controller of the hoist includes a lift up button which is adjustable in a pressed degree; a lift down button which is adjustable in a pressed degree; a lift up switch disposed below the lift up button so as to be immediately operated when the lift up button is pressed; a lift down switch disposed below the lift down button so as to be immediately operated when the lift down button is pressed; a magnet body connected to both of the lift up button and the lift down button and disposed to descend during a pressing operation of the lift up button or the lift down button; and a Hall sensor disposed to correspond to the magnet body so as to detect a descending degree of the magnet body being pressed by the lift up button or the lift down button.

A crane system includes crane with a load hook that can be raised or lowered via movable crane elements, and moved within a crane working area by operating drive units associated with the crane elements. The crane system further includes a control unit and a mobile transponder that can be variably positioned in the crane working area, and one or more transmitting/receiving units communicatively coupled to the control unit and configured to receive signals transmitted by the mobile transponder. The control unit is configured to automatically determining the current position of the mobile transponder relative to the load hook and/or a crane element based on the signals received from the mobile transponder, and automatically control the drive units in such that the load hook is automatically moved to the mobile transponder.

A working machines capable of securing safety while enabling remote operation is a working machine configured to be capable of communicating with a remote operation device (40), and includes a communication unit (70a) that receives a manipulate signal from the remote operation device (40), a control unit (70) that controls actuators (51 to 59) mounted in the working machine according to manipulate signals from main operation devices disposed in a cab of the working machine or the remote operation device (40). In a case where a state of the working machine does not fulfill a predetermined condition, the control unit (70) does not allow the remote operation of at least one of the actuators (51 to 59) by the remote operation device (40).

A battery device has a housing adapted to be attached to a controller for operating a crane and to be powered by the battery device, a battery cell, and electronic circuitry connected to the battery cell and electrically connectable to the controller. A memory is provided in the electronic circuitry, wherein a function of the controller depends on the information in the memory. By providing a controller adapted to operate in one of a plurality of operating modes, wherein the operating modes comprise any of the following: an operation mode for controlling the operation of a crane, a simulation mode for communicating with a simulation device for simulating a crane, and a demonstration mode for demonstration of the different functions of the controller for controlling a crane, a controller for a crane is provided in which the selection of functions can be done in a controlled and defined way.

A system including a control station and at least one controlled device, the control station including at least one control device intended for controlling at least one action of the controlled device, the control device including a haptic interface including at least one element for interacting with the user, and a controller configured to send orders to the haptic interface to generate haptic stimulations in the element for interacting with the user on the basis at least of information relative to a state of the controlled device and/or the environment thereof.

Crane assemblies for attachment to a vehicle tow hitch are described.
