Abstract
A railroad car positioning apparatus for positioning a railroad car along a railroad track includes a battery-powered and radio-controlled carriage assembly and first and second dog members mounted on the carriage assembly. The apparatus includes a main control unit for controlling the carriage assembly. The carriage assembly is controlled via radio communication between the carriage assembly and the main control unit. The dog members are generally extendable to an axle height of the railroad car to be acquired for contacting one of the axles of the railroad car. The apparatus further includes a plurality of hydraulic cylinders for moving the carriage assembly in a forward or reverse direction on a guide way disposed between the railroad tracks on which the railroad cars travel. The batteries on the carriage assembly may be remotely recharged using a contactless power transfer device, which includes a battery recharging device situated on the guide way.
