Fish plate clamp for unloading rails

A fish plate clamp (10) for unloading rails (1), that comprises a support element (11, 12) that comprises a first piece (11) and a second piece (12) adapted so that each one is located on a face of the rail (1) at an end of said rail (1), characterized in that:

• each piece of the support element (11, 12) comprises and internal mortise (13) on its face destined to be placed adjacent to the rail (1), the internal mortises (13) being adapted to be placed facing the area of the (3) web of the rail (1).
• a first and second gripping element (14) of the rail (1) each one located in an internal mortise (13) of the support element (11, 12) in such a way that the gripping element (14) is movable with respect of the support element (11, 12) in the longitudinal direction of the rail (1),
• where the internal mortises (13) comprise an inclined surface (15) in a manner that the internal mortise (13) longitudinally decreases in depth towards the end of the fish plate clamp (10) destined to lodge the end of the rail (1), the gripping elements (14) and the internal mortises (13) being configured in a manner that when the gripping element (14) moves along the length of the inclined surface (15) of the internal mortise (13) in the direction in the pulling of the rail (1), the gripping element (14) latches onto the web (13) of the rail (1).
