Method for allocating electrical power to crane equipment

A crane comprising electrical equipment intended to be electrically powered from at least one power supply source capable of providing an available maximum power which corresponds to a maximum power that can be delivered by the at least one power supply source, said electrical equipment comprising actuation equipment defined according to a configuration of the crane and accessory equipment, wherein said crane comprises a control/command unit configured for the implementation of an allocation method for allocating the available maximum power from the at least one power supply source to the electrical equipment of a crane, wherein said allocation method being implemented by said control/command unit comprises a step of selecting between:

• a raw mode in which the available maximum power is allocated over predefined actuation equipment and over predefined accessory equipment 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 cut-off conditions associated to the accessory equipment, so that according to their respective cut-off conditions the accessory equipment are powered or not,
• wherein said control/command unit is connected, on the one hand, to an interface allowing a selection between the raw mode and the optimized mode and, on the other hand, to an electrical circuit connecting the at least one power supply source to the electrical equipment to control an allocation of the available maximum power according to the selected mode among the raw mode and the optimized mode.
