An overhead chain conveyor device is provided to improve an upper dog of a front trolley so as to prevent non-uniform transfer of a hanger body caused by pulsation or surging of a free chain unit. An overhead chain conveyor device(100) includes a power chain unit(10) and a free chain unit(50). The power chain unit includes a chain(11) and a pusher(21) fixed to the chain and transfers power to a hanger body which supports a car body. The free chain unit corresponds to the power chain unit and has a front trolley(31) and a rear trolley connected to the hanger body. The pusher includes a first part fixed to the chain and a second part projected downward. The front trolley includes a front dog(35) and an upper dog(38) linked to the front dog. |
