PURPOSE: A crane moving along multiple rails is provided to control the horizontal movement of the crane by supporting a main body of the crane. CONSTITUTION: A crane moving along multiple rails comprises wheel support units(180) and an auxiliary cable(150). The wheel support units are formed on the side surfaces of wheels moving on a main rail. The wheel support units have concave units. The auxiliary cable is coupled to a cable support unit(190). One end of the cable support unit is coupled to the leg, and the other end has a concave unit. The wheel support units are slid along a first auxiliary rail(280). The auxiliary cable is slid along a second auxiliary rail(290).
