A lattice tower or truss tower is a freestanding framework tower. They can be used as electricity transmission towers especially for voltages above 100 kilovolts, as a radio tower (a self-radiating tower or as a carrier for aerials) or as an observation tower.

steel lattice tower station ,tower body lifting principle: the integrated base station tower body is the socket structure, can realize the lifting function.
The principle is that the lifting tower by the base section, the secondary section and the distal end through each other set up the lifting device is connected in turn, wherein the basal section, the secondary section and the distal end are composed of the closed metal structure or the frame type metal structure respectively.
