Abstract: A controller for controlling the operation of a crane has a control panel for the control of different functions of the crane, a two-way communication radio unit adapted to transmit and receive information from/to the controller, and a processing means connected to the control panel and the communication radio unit and adapted to control the function of the controller. The processing means, when in an operation mode, is adapted to communicate with the crane for controlling the operation of the crane, and when in a simulation mode, is adapted to communicate via the communication radio unit with a remote simulator device adapted to simulate the operation of a predefined crane. The communication radio unit is adapted to operate in the 2.4 GHz Bluetooth band. The same controller can thereby be used for both operation in the field and for a learning process.

Abstract: 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.

Abstract: The present invention relates to an actuator (2) for controlling and observing functions of a machine, comprising two or more hand-operated control members (3-8), functional display elements connected to each control member. Each of said hand-operated control members (3-8) are arranged to control one or more functions included in different functional groups (16-20). Said functional display elements comprising one or more electro-optical displays (12, 13) divided into one or more display sections (24-29), whereby each display section is connected to a certain control member and has a specific logical positions in relation to this control member, and is arranged to show the function that is controlled by this controlled by this control member (3-8) and also to show information about the status of functions of the machine. The present invention also relates to a computer program product to am actuator according to the present invention.
