When hoisting, the wire rope is passed around the pulley on the crane, and the crane is hoisted. As one end of the tower moves upwards gradually, the angle of the lifting ring and the fixed plate changes accordingly by rotating the connecting device. Moreover, since the hooks at both ends of the wire rope are respectively hooked in the rings on the two fixed plates that mirror each other with the horizontal plane where the tower axis is located as the reference plane, the length of the wire rope bypassing the pulley also increases with the hoisting. The process is constantly changing, so that the consistency of the force of the wire rope and the uniformity of the length change ensure the installation of the hoisting and improve the efficiency of the hoisting.
