The radio and television tower is equipped with a platform for process, Liaowang and other purposes. The level, number and arrangement height shall be determined according to the use requirements. The shape of the platform depends on the section of the tower body. The components of the platform structure are generally made of angle steel, channel steel, I-beam and other section steel. In order to facilitate high-altitude installation, the components are first connected into hoisting units by welding, and the units are connected by bolts.
