計、製作のまちがい等も生じ易い。 The pulley type balancer is supported on a steel tower erected on the side of the overhead wire, and pulls the overhead wire at a certain angle with respect to the direction of the overhead wire. Therefore, the fitting for attaching the balancer to the prismatic steel tower needs to hold the balancer obliquely to the side of the tower. For this reason, conventional mounting brackets
It is necessary to design and manufacture a right-handed or left-handed balancer with different angles depending on the conditions of the location where the balancer is installed, which is not only time-consuming but also prone to design and manufacturing errors.

状鉄塔Ｐを抱持するものとする。 Embodiments of the present invention will be described below with reference to the drawings. The mounting bracket is made up of a main body 1 made of angle steel assembled into a rectangular frame shape, and a bracket 2 fixed to the center of one side of the main body with bolts and nuts 3, and holds a prismatic steel tower P.
