Bridge manufacturing method involves articulating end point of support rod with bridge carrier, and column, a bridge carrier with end points and support rod with end points is manufactured in perpendicular position

摘要

This method is related to terminal (3) and bridging carrier (2) of hinged support bar. There is endpoint (9) and support rod and endpoint (5,6) to be fabricated in upright position for column (4), bridging carrier. Terminal support rod is hinged on column. Bridge carrier starts horizontal position and passes through the column of the crown cut support of the terminal of vertical movement. Mobile endpoint crown cut support press-fit is connected with column. Independent claim also includes lift bridge.
