120m Heavy-Duty Broadcast Tower with Integrated Elevator

Engineered for superior performance and longevity, the SOLARTODO 120-meter Heavy-Duty Broadcast Tower is a state-of-the-art infrastructure solution designed to meet the rigorous demands of modern broadcasting and telecommunications. This lattice-type tower, constructed from high-strength structural steel, provides a robust platform for a multitude of antenna systems. Its defining feature is a fully integrated elevator, ensuring safe, efficient, and rapid access for maintenance personnel and equipment to any of its eight antenna platforms. Designed to withstand extreme environmental conditions, including wind speeds up to 55 m/s (200 km/h), this tower guarantees exceptional stability and operational reliability. It complies with leading international standards, including TIA-222-H and EN 1993-3-1, making it a globally recognized solution for critical broadcasting infrastructure. With a design life of over 30 years, the SOLARTODO 120m tower represents a long-term investment in quality and performance, supporting everything from national television and radio broadcasting to advanced 5G telecommunication services.

The structural integrity of the 120m Broadcast Tower is founded on a heavy-duty triangular lattice design, optimized for strength-to-weight ratio and minimal wind resistance. The primary material is high-tensile Q345 grade angle steel, a material renowned for its excellent mechanical properties and weldability, conforming to the GB/T 1591 standard. The total steel weight of the structure is approximately 95 metric tons, a testament to its robust construction. Every steel component undergoes a hot-dip galvanization process in accordance with ISO 1461, which provides a thick, durable zinc coating with a minimum average thickness of 85 micrometers. This coating offers superior corrosion protection, ensuring the tower's longevity even in harsh coastal or industrial environments. The tower is engineered to withstand a design wind speed of 55 m/s (equivalent to a Category 3 hurricane) without ice, and can support a substantial total tip load of over 5,000 kg. All structural bolts and connections are Grade 8.8 high-tensile fasteners, ensuring secure and lasting joints that are critical for the overall stability of such a tall structure.

Versatility is at the core of the tower's design, which features eight distinct antenna platforms strategically positioned at various elevations. This multi-level configuration allows for optimal frequency separation and minimizes interference between different broadcast services. The structure is engineered to support a dense arrangement of up to 30 large antennas, including heavy UHF/VHF broadcast panels, high-gain microwave dishes, and 5G Massive MIMO arrays. The spacious platforms, each providing over 15 square meters of usable area, are equipped with universal mounting pipes and brackets, offering flexibility for installing a wide range of antenna types and sizes. An integrated cable management system, featuring 600mm wide vertical cable trays, protects and organizes the extensive coaxial and fiber optic cabling required for the 30 antenna systems, running from the base equipment shelter to the top of the tower. This high capacity makes the tower an ideal hub for co-location, enabling multiple broadcasters and telecom operators to share a single, powerful infrastructure platform.

A key innovation of this tower is the fully integrated elevator system, designed to enhance safety and operational efficiency. The elevator provides all-weather access along the entire 120-meter height, drastically reducing the time and physical effort required for routine inspections and emergency maintenance. The cabin is designed for a capacity of 3 persons or a 300 kg payload, traveling at a safe and efficient speed of 0.6 m/s. The system is compliant with the ASME A17.1 and EN 81-41 safety codes for vertical platform lifts, incorporating multiple redundant safety features. These include an automatic emergency braking system, an overload detection sensor, an uninterruptible power supply (UPS) for the cabin lighting and communication system, and a two-way voice communication link to the ground control room. The elevator shaft is fully enclosed, protecting the mechanism from adverse weather and ensuring reliable operation year-round. This feature not only improves technician safety by eliminating the need for long, strenuous climbs but also reduces tower maintenance downtime by up to 75%.

Safety is paramount in the design of the SOLARTODO 120m tower. A comprehensive lightning protection system, compliant with the IEC 62305 standard, is integrated into the structure. It consists of multiple air terminals at the apex, a dedicated copper down-conductor, and a low-impedance grounding grid designed to achieve a ground resistance of less than 4 ohms, effectively dissipating the energy from a direct lightning strike. For aviation safety, the tower is equipped with a dual-mode aircraft warning light system that meets ICAO Annex 14 and FAA AC 70/7460-1L specifications. This includes high-intensity white strobes for daytime and medium-intensity red lights for nighttime operation, ensuring 24/7 visibility to aircraft. To prevent unauthorized access, a 3-meter high anti-climbing barrier is installed at the base of the tower. The combination of high-quality materials, superior corrosion protection, and a robust design compliant with TIA-222-H standards ensures a minimum operational design life of 30 years with minimal maintenance, and potentially over 50 years with a proper inspection and upkeep program.
