Insight to the design of crane wheel aspect of E.O.T crane and study on E.O.T crane wheel life improvement

The present work deals with designing and analysis of crane wheel of E.O.T cranes that runs on a rail span of 34 meters. Weight of crane is 150 T and working load of 16 to 20 T. E.O.T crane consists of 8 wheels and all these wheels are subjected to total load of crane (170 T). hence wheels are subjected to more were and tear. To overcome this problem, different parameters like wheel diameter, width of tread, depth of flange and thickness of guiding wheel flange at the base, are to be adopted carefully. Crane wheels have straight tread. To guide the crane properly and to prevent its derailment, they have flanges. In case of flangeless wheels there are guide rollers on both sides of track rails. The wheels are mounted is such a way that they enhance /facilitate removal and replacement will be easy. The wheel tread width is greater than rail head by such an amount which can facilitate for known variation in the gantry rail alignments and gantry track span dimensions.
