A low space crane using a rail girder is provided to reduce a concentrated load by dispersing a vertical load of a weight which is applied to a hook. A low space crane using a rail girder includes a rail girder(200), a hoist frame(410), a support cover section(490), a hook section(500), and a hoist section(400). The hook section includes a sheave and a sheave cover. The sheave is rotatably connected to a wire drum and a wire rope. The sheave and a hook suspending a weight are fixed to the sheave cover. An upper transverse wheel section to which a transverse motor is connected for transverse movement of the hoist frame is fixed to the hoist section. |
