Abstract
The invention relates to a predictive maintenance of hoisting equipment (102), particularly cranes. A maintenance centre (106) automatically collects diagnostic data relating to least one component of the remote hoisting equipment and optionally sensor data relating the operational environment of the remote hoisting equipment (102). The maintenance centre (106) has an access to configuration data of the remote hoisting equipment and the reliability data on the at least one component of the remote hoisting equipment (102). The maintenance centre (106) is then able to generate a maintenance plan optimizing the cost of maintenance and reliability of the hoisting equipment over a life cycle of the hoisting equipment.

15. A predictive maintenance method of hoisting equipment, particularly cranes, comprising the steps of:
-
receiving and automatically collecting, at a maintenance centre, diagnostic data relating to at least one component of a remote hoisting equipment; receiving and automatically collecting, at the maintenance centre, sensor data relating the operational environment of the remote hoisting equipment at least from a corrosion sensor and/or an accelerator sensor installed at the remote hoisting equipment, said data from the corrosion sensor comprising data representing a corrosive effect of the environment on electrical devices of the remote hoisting equipment and/or said data from the accelerator sensor comprising the data of external shocks to and collisions of the remote hoisting equipment; providing configuration data of the remote hoisting equipment; providing reliability data on said at least one component of the remote hoisting equipment; and automatically generating, based on said diagnostic data, configuration data, reliability data and said operational environment data, a maintenance plan optimizing the cost of maintenance and reliability of the hoisting equipment over a life cycle of the hoisting equipment. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A predictive maintenance system comprising at least one computer and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least computer, cause a predictive maintenance of hoisting equipment, particularly cranes, said predictive maintenance comprising:
-
receiving and automatically collecting, at a maintenance centre, diagnostic data relating to at least one component of a remote hoisting equipment; receiving and automatically collecting, at the maintenance centre, sensor data relating the operational environment of the remote hoisting equipment at least from a corrosion sensor and/or an accelerator sensor installed at the remote hoisting equipment, said data from the corrosion sensor comprising data representing a corrosive effect of the environment on electrical devices of the remote hoisting equipment and/or said data from the accelerator sensor comprising the data of external shocks to and collisions of the remote hoisting equipment; providing configuration data of the remote hoisting equipment; providing reliability data on said at least one component of the remote hoisting equipment; and automatically generating, based on said diagnostic data, configuration data, reliability data and said operational environment data, a maintenance plan optimizing the cost of maintenance and reliability of the hoisting equipment over a life cycle of the hoisting equipment.
