Abstract

The invention relates to an electric transmission line iron tower erection tower crane with flexible base and flexible adhesion for electric transmission line iron tower erection construction. The bottom of the crane is positioned on the simple base at the center of the iron tower; the four bases of the iron tower are connected with each other by base pull wires; and the angles between the base pull wires and a horizontal plane are 40-50 degrees. The simple base and the base pull wires jointly form a flexible base of the crane. After the iron tower is erected at a certain height, main materials at each side of the iron tower are connected with a tower body of the crane by the adhesion pull wires to form flexible adhesion of the crane. The quantity of the adhesion is ensured according to the height of the iron tower and the adhesion distance of the crane. The simple base is generally formed by paving road woods on sands, and the base pull wires and the adhesion pull wires are formed bysteel wire rope chain wheels.
