摘要

The present invention relates to a tire-type gantry crane with a wireless power supply. More specifically, the present invention relates to a trackless tire-type gantry crane which is able to receive a power supply wirelessly from the ground by using a magnetic resonance method and to store the power in a battery or to supply power to each apparatus of the crane. According to the present invention, the tire-type gantry crane comprises: a crane main body which uses a tire as a supporting and moving means, and has a rechargeable battery mounted; a current collection unit which receives power from an electricity feeding unit installed on the outside, and transfers the power to the rechargeable battery or to an apparatus installed on the crane; and a pick-up apparatus which moves the current collection unit to allow the current collection unit to approach the electricity feeding unit.
