An allocation method for allocating an available maximum power from at least one power supply source to electrical equipment of a crane, in which the electrical equipment are powered with the available maximum power, includes selecting between: a raw mode in which the available maximum power is allocated over predefined actuation equipment and on accessory equipment predefined among the electrical equipment, the actuation equipment being defined according to a configuration of the crane, and an optimized mode in which the available maximum power is allocated over the predefined actuation equipment, and also over the accessory equipment but according to the cut-off conditions of the accessory equipment, so that according to the cut-off conditions the actuation equipment are powered or not.

A tracked vehicle, controller for the tracked vehicle, and a method performed thereon are provided that enable the pilot to steer the tracked vehicle using an existing joystick of the tracked vehicle.

An adjusting device for operating machines is equipped with: a control unit; input units connected to the control unit; and a display unit connected to the control unit. The control unit stores the item ID and adjustment value of each of a plurality of adjustment items. Upon receiving a change operation, the control unit changes the adjustment value of a specified adjustment item to a specified value. Upon receiving a change end operation, the control unit displays, on the display unit, the item ID and the adjustment value corresponding to the adjustment item with the adjustment value changed.

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.
