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 compact wireless remote control for the wireless remote control of a machine is described, having an upper-face operating surface having a display device and at least one free space which is below the upper-face operating surface so as to be at least partly covered by same, is open towards the outside at least laterally on one side, and is delimited by wall portions of the wireless remote control. At least one operating element which can be actuated by an operator at least from the open lateral side of the free space is provided on at least one of said wall portions on the free space side. The free space is preferably formed continuously from one lateral side to the other lateral side and is open at both lateral sides. At least one operating element in each case can be manually accessed from each open lateral side for actuation.

A notification system includes: a notifier which notifies an operator of a state of a lifting magnet; a sensor which detects at least one of a voltage, an electric current, and an electric power supplied for exciting the lifting magnet; a determination part which determines, based on detection data from the sensor, whether an attraction quantity of the lifting magnet reaches a maximum attraction quantity after excitation of the lifting magnet is started; and a notification control part which causes the notifier to notify that the attraction quantity reaches the maximum attraction quantity when the determination part determines that the attraction quantity reaches the maximum attraction quantity.

A control switch for operating a crane. The control switch includes a first interface designed to transfer signals between the control switch and a control unit of the crane. In order to combine, in particular, the robustness and operating reliability of the control switch desired in industrial use with increased functional scope in a cost-effective way, the control switch is provided with a second interface designed to transfer signals between a mobile terminal and the control switch in order to add functions of the mobile terminal to the functional scope of the control switch.

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.

A remote operation terminal (32) of a crane (1) provided with a GNSS receiver (30) for calculating the current position of the tip of a boom (9); acquires attitude information of the crane (1) and the current position of the tip of the boom (9) from a control device (31) of the crane (1); generates a three-dimensional image (G) of the crane (1) at the current time and planimetric features on the basis of the information acquired from the control device (31) and three-dimensional information acquired by a three-dimensional information acquisition unit (42); displays, on a display device (40), the generated three-dimensional image (G) at the position of and in the direction of a viewpoint input to a viewpoint changing operation tool (34); and generates a control signal for the crane (1) so that the tip of the boom (9) of the three-dimensional image (G) moves in a moving direction input to a suspended load. moving operation tool (35) in the three-dimensional image (G) of the crane (1) displayed on the display device (40).

A crane is provided. The crane includes an acceleration sensor that detects the acceleration of a load, wherein a target velocity signal is converted into target location coordinates of the load, current location coordinates of a boom are calculated from a slewing angle, a luffing angle, and an expansion/contraction length, the spring constant of a wire rope is calculated from the previously calculated location of the load from a unit time earlier, the current location coordinates of the boom, and the current accelerations of the load as detected by the acceleration sensor, target location coordinates of the boom are calculated from the accelerations, the spring constant, and the target location coordinates of the load, and an actuator operation signal is generated.
