PURPOSE: An H-beam trolley hanger capable of enabling curve running is provided to have operational reliability by preventing the trolley hanger from stopping in linear and curved portions due to the biased center of gravity. CONSTITUTION: An H-beam trolley hanger(1) capable of enabling curve running comprises a first bracket(2), horizontal guide rollers(4), vertical guide rollers(5), rolling support members(7), and a guide member(12). The first bracket has a horizontal face(2a) and left and right vertical faces(2b). The horizontal guide rollers are installed on the left and right vertical faces of the first bracket in order to roll an H-beam on the horizontal face. The vertical guide rollers are installed on second brackets(6), fixed on the left and right vertical faces of the first bracket, to roll while selectively contacting to the vertical faces of the H-beam. The guide member is installed at the center of the underside of the horizontal face of the first bracket by a first pin bolt(11) in order to restrict the movable range with a stopper(19). First and second coupling holes(15,16) are formed on the guide member in order to pass an electric cable and an air hose. |
