摘要： An adjustable crane rail brace that provides for lateral movement of a crane rail having a rail base resting upon a tie plate. The brace includes a block mounted to the tie plate and a wedge interposed between the block and the rail base. The wedge is slidable longitudinally with respect to the rail base. The block is mounted at an acute angle with respect to the lateral edge of the rail base, and the wedge has sides at this acute angle with respect to each other. The wedge also has a first serrated portion. The brace includes a member having a top face and having a second serrated portion. The first and second serrated portions are in frictional engagement, and the member has a resilient nose extending downwardly in contact with the rail base. The brace further has a spring for exerting downward force upon the top face.
