In this paper, to introduce the gantry to strawberry house, the permissible limit of gauge irregularity for gantry was clarified. In this experiment, the lateral and wheel loads acting on the track were measured. Both-flanged wheel with flange angle 90° that was conventionally used could travel at a gauge irregularity of 16mm because of side-frame deformation. Side-flanged wheel with flange angle 65.3° could travel along the rail with the gauge irregularity until it finally got derailed at a gauge irregularity of 12mm. This experimental value agreed well with the gauge irregularity value of 11.7mm computed from the theoretical derailment quotient 1.02. In addition, the power consumption of the driving motor with side-flanged wheel was proven to be low. Consequently side flanged wheel was suitable for practical use.
