Abstract

A monitoring method is designed, in a first step, to monitor and assess the electric power consumptions of the electrical equipment of a crane over a given time period. The electrical equipment includes actuation equipment contributing to at least one movement of the crane and accessory equipment not participating in a movement of the crane and responsible for power consumer functions. Once the time period is completed, the monitoring method is designed to determine whether, over the time period, the crane has, or has not, consumed too much power, this excessive consumption being deduced by comparing a supply power provided to the crane by at least one power supply source with the electric powers that the actuation equipment and the accessory equipment have consumed.
