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
