A clamping device for a rail of a crane is provided to stably apply support force to the rail by a double structure and to uniformly apply elastic stress to various shapes of rail coupling surfaces by forming a plurality of contact protrusions in an elastic support body along a length of the rail. A clamping device for a rail of a crane includes a base plate(10), two coupling bolts(20), a pressure plate(30), an elastic support body(50), and two coupling nuts(40). The base plate has two coupling grooves(12) at a predetermined interval along a length of the rail and a welding hole(14) to be additionally welded with a top plate of the rail. Each of the two coupling bolts is composed of a screw part(24) inserted into the coupling groove of the base plate and a head unit(22) supported by the coupling groove. The pressure plate has two coupling holes(32) at a predetermined interval to insert the coupling bolts and an assembling groove(34) at an end of a horizontal unit. The elastic support body has one side inserted into the assembling groove of the pressure plate and is in contact with a surface of the rail. The two coupling nuts are coupled with the screw parts of the coupling bolts inserted through the coupling holes of the pressure plate. |
