The tianhemast tower Model TMS-147 is a self-supporting (subject to strict load & environmental conditions) and guy capable telescopic structure with an extended height of approximately 45m (147ft) above ground level (AGL). The tower is composed of six 9m each heavy-duty, hot dipped galvanized steel telescoping lattice sections mounted to a 90degree tiling mechanism structural base. The tower is tilted to the vertical position by tandem heavy duty hydraulic cylinders and automatically elevated by spindle drive with a 12kw motorized belt gear system. While extending section one by one, the tower locked automatically by itself from four-way latch pins, each latch pin suffers max 6T capacity, so four pins can have the capacity 12T max for total system.
To ensure the safety of the tower operation, several limited switches has been applied to the tower system, while the mast extended to its full position, an upper limited switch will automatically disconnect the motor electric circuit. Secondly, if the limited switch is broken, the spindle itself will loop freely without coupling with the screw nut which is mounted on bottom of each tower section.
Our tower advantage is that our team designed spindle screw system that eliminate stainless steel rope for tower operation which is safer and easier for operation without stainless steel rope and its redundancy rope system that is very complicated for operation and its time-consuming maintenance.
