TRIANGULAR DEVICE LIFTS CANTILEVERED GIRDERS TO SPAN PIERS

This article describes a free-advance erection method employing a triangular lever to lift deflecting cantilevered webs into place. The triangular rig is built of tubular steel in the shape of an isosceles triangle, one corner of which can be set in a recess cast in the side of each pier so that the piers function as a fulcrum. The entire set-up operation takes 1.5 to 2 hours.
