摘要

PURPOSE: An overhead crane in which an operator boards is provided to minimize damage of an electric cable by applying a cable bear to a caterpillar type transferred on a guide rail of a girder with a bare frame. CONSTITUTION: An overhead crane in which an operator boards comprises a girder(110) and a trolley(120). The girder drives on a fixing frame in a longitudinal direction. The trolley drives on the girder in a longitudinal direction. Two guide rails(200) are equipped on one side of the girder to be perpendicular to the longitudinal direction. A cable bear(300) of a caterpillar type is connected to the trolley through a parallel beam to be reciprocated with the trolley on the guide rail and a bare frame is equipped on the inside to be slid while the cable bear maintains the caterpillar type.
