Tubular Tower, which belongs to the technical field of Tubular Tower, includes a work platform for connecting the tower body and the upper part of the tower body. Defines the bottom of the tower wall openings, which wall defines the position of the work platform openings, the antenna holder fixed to the working platform fences, wherein the connector body is provided by a column ladder main rod connected to the main pole and ladder provided The ladder formed by the crosspiece is fixedly connected with the supporting frame of the ladder main rod, and the supporting frame is screwed and matched with the connecting bracket arranged on the inner wall of the tower.

The single Tubular Tower includes a tower and a work platform connected to the upper part of the tower body. The antenna bracket is fixed on the fence of the working platform, and is characterized in that the ladder is composed of a ladder block connected to the main pole of the ladder and the main pole of the ladder. The main pole of the ladder is fixedly connected with the supporting frame, and the supporting frame and the supporting frame are arranged on the tower. The inner wall of the connection bracket is screw-fitted.
The advantages of a single Tubular Tower are:. The structure is simple and reasonable; the appearance is beautiful; the installation is easy to use and the floor area is smaller than that of the angle steel tower. In terms of safety, the angle tower is higher than the single tower tower, although the single tower tower is the protagonist. However, if the single-Tubular Tower is to achieve higher safety, only the rod diameter should be increased, the wall should be thickened, and high-strength steel should be used for the material. There will be high cost. .
The tower body adopts a more reasonable segment and is connected with a high-strength bolt through a connector, so that the installation is convenient and quick, and it can adapt to the installation of a variety of more complex field sites. The built-in ladder and wiring way can not only provide the operator with a convenient and safe operating environment, but also can avoid the sun and rain from the feeder, greatly prolonging the service life of the feeder, and the center of gravity of the tower will not be offset due to the installation of the feeder. The bottom of the tower body is fixed with double nuts. This structure can finely adjust the verticality of the tower body and ensure the installation accuracy more effectively. In the production, large-scale CNC automatic cutting machines, multiple sets of CNC automatic submerged arc welding manipulators, and advanced equipment such as large arc down-adjusting hydraulic coiler with pre-bend function, ultrasonic testing equipment, and abundant manufacturing experience, The entire production process realizes automated flow operations, so that the product quality is stable and reliable.
