Design improvement of crane heavy-duty truck traveling steel rail base

The invention relates to design improvement of a concrete base (7) of a gantry crane heavy-duty truck traveling steel rail, comprising a steel plate large substrate (6) below a steel rail (1). A compression bolt (2) is connected with a steel plate large substrate (6) for compressing the steel rail....

description The invention relates to design improvement of a concrete base (7) of a gantry crane heavy-duty truck traveling steel rail, comprising a steel plate large substrate (6) below a steel rail (1). A compression bolt (2) is connected with a steel plate large substrate (6) for compressing the steel rail. A method of reducing the central distance of a cushion plate or increasing the width of the cushion plate can be used to make the positive pressure application area of the steel rail on the base large and further reduce the unit area pressure applied on the concrete and prevent the formation of concave traces due to concrete super pressure resisting limitation. The loading capability of the concert base can be improved by the action of the large steel plate substrate. The design improvement is also applied to concrete base with pre-embedded compression bolt.
