PURPOSE: A gantry crane is provided to conveniently install in an apartment-style factory without additional H-beam pillars and to widely apply to seashore zones and bridge constructions because the influence of wind load is small when being used to the outdoor. CONSTITUTION: A gantry crane is comprises driving rail parts(1A,1B), driving parts(2A,2B,2C,2D), main bridges(3A,3B,3C,3D), a girder part, trust connection bars(8A,8B), and a screw hook for a lug. The driving rail parts are parallelly arranged in a foundation bed. The driving parts move on the driving rail parts. The main bridges are detachably coupled at the top of the driving parts. The girder part comprises girder piers(6A,6B,6C,6D) and girders(7A,7B). The trust connection bars are detachably coupled between the girder piers. The screw hook for a lug is arranged at the bottom of a lift beam(11). |
