The present invention relates to a remote control device for a crane, a construction machine and/or an industrial truck, comprising a mobile end device in the form of a tablet computer that has a screen having a touch-screen function and at least one input means for inputting control commands in the form of a touch-screen display means, as well as a signal transmission device for transmitting the input control commands to the control apparatus of the crane, of the construction machine and/or of the industrial truck. It is proposed to use the screen of the tablet computer not only to input and display control commands, but also to present actual images and/or desired images of the working environment of the machine so that, on an inputting of control commands via the touchscreen function of the screen, the machine operator can simultaneously monitor the working environment there.

A laser positioning system is used in association with a crane within a manufacturing facility. The laser positioning system includes a laser source that is mounted on an immovable or non-moving wall or surface in the manufacturing facility. The laser source on the wall or surface ensures that the laser beam does not skew out of square relative to the movement of the crane to various locations in the facility.

A crane is provided. A slewing base camera detects a load W that is suspended by a wire rope, the current coordinate location of the load is calculated from the location of the detected load, the current coordinate location of a tip end of a boom is calculated from the position of a crane, a target velocity signal that was inputted from a manipulation tool is converted into a target coordinate location of the load, a wire rope direction vector is calculated from the current coordinate location of the load and the target coordinate location of the load, a target location of the tip end of the boom for the target coordinate location of the load is calculated from a wire rope reel-out amount and the wire rope direction vector, and an actuator operation signal is generated.
