ABSTRACT:
The present application describes a rail clip assembly, particularly but not exclusively for securing a crane rail to a flanged girder. The assembly comprises a first part adapted to be attached to the rail support surface adjacent the rail, a second part overlying the first part and having a lateral surface for abutment with a lateral face of the rail, and a bolt for fixing the second part to the first part independently of attachment of the first part to the rail support surface. The parts have aligned apertures through which the bolt extends, one of the apertures being elongate to enable the second part to assume different positions relative to the first part. The elongate aperture extends in a direction inclined at an acute angle to the longitudinal direction of the rail. The first and second parts have cooperating laterally directed surfaces which are abutted in all relative positions of the parts for transmitting to the first part laterally directed forces applied to the second part by the rail. The laterally extending surfaces extend parallel to the direction of extent of the elongate aperture. The first part has parallel upper and lower surfaces and the second part has an upper surface which, adjacent the aperture, is inclined to the horizontal away from the direction of approach of the cooperating laterally directed surfaces to the rail. The bolt extends through the apertures in a direction perpendicular to the inclined surface of the second part and is thus inclined with respect to the vertical.
