Title: METHOD AND SYSTEM FOR STEERING A GANTRY CRANE
Abstract:
A method for steering a gantry crane (12) having wheel assemblies (30, 32, 34, 36) comprises the steps of: initiating movement of the gantry crane (12); and rotating the wheel assemblies (30, 32, 34, 36) wherein the front wheel assemblies (32, 36) rotate in a first rotational direction and the rear wheel assemblies (30, 34) rotate in a second rotational direction, the first rotational direction being opposite to the second rotational direction and wherein a first side wheel assemblies (30, 32) rotate at a first rotational speed and a second side wheel assemblies (34, 36) rotate at a second rotational speed, such that the gantry crane (12) moves from a linear path to an arcuate path with a turning radius decreasing to substantially zero for rotation about a central axis.
