The present invention relates to heavy construction equipment having an electricity supply device. More specifically, the present invention relates to heavy construction equipment having an electricity supply device, which includes a first transfer rail installed on a ceiling of an indoor working space; a transferring means coupled to the first transfer rail to be slid along the longitudinal direction of the first transfer rail; a vertical supporting portion connected to a lower portion of the transferring means; a boom stand coupled to a lower end of the vertical supporting portion by a hinge; a control panel to which one end of an electricity cable to supply electricity to the heavy construction equipment is connected, and which is installed inside the indoor working space; and a post to which the other end of the electricity cable is connected to receive the electricity supplied by the control panel, and which is vertically installed at an upper portion of the heavy construction equipment. According to the present invention, by using a balance weight to minimize load applied to the electricity supplying cable during a power supply process by a moving means mounted on the rail on the ceiling when moving due to location movement of the electric heavy construction equipment receiving electricity during an indoor working process, damages to the cable can be prevented, smooth movement of the heavy construction equipment is possible, and constant tension of the cable can be maintained. |
