A method for operating a hoisting appliance spanning a hoisting area, the hoisting appliance including N2 movable parts for the transport of a load from a starting point to a destination point, the N movable parts being configured for a linear movement along any of three X, Y and Z orthogonal axes or for an angular movement. The method includes choosing speed parameters for displacement of the N movable parts for transporting the load from the starting point to the destination point, by, in a control device: determining a set of speed parameters for displacement of the N movable parts belonging to an operating zone for which a predictive maintenance function of the hosting appliance yields results which are above a determined accuracy threshold; and selecting, among the set, speed parameters which minimize a travel time of the load from the starting point to the destination point.

A health monitoring system for a crane (10) includes a wheel assembly (50, 70) having a wheel (120) with an axle (160) defining an axis (172) of rotation of the wheel. The health monitoring system further includes a plurality of strain gauges (208) coupled to the axle at circumferential locations around the axis of rotation. The strain gauges continuously detect strains experienced at the wheel. The health monitoring system further includes a data acquisition system (200) coupled to the wheel that receives data from the strain gauges corresponding to detected strains. The health monitoring system further includes a main controller (204) coupled to the data acquisition system. The main controller receives data from the data acquisition system corresponding to the detected strains, uses the data to calculate loading applied to the wheel assembly continuous in real-time in both a first direction, a second direction perpendicular to the first direction, and a third direction perpendicular to both the first direction and the second direction.
