Our Versatile Second-Hand Flat-Head Tower Crane, meticulously engineered by Hebei Borsese Trading Co., Ltd., stands as a paragon of safety and efficiency in the construction realm. This remarkable crane is outfitted with a comprehensive suite of advanced safety hoisting modules, including anti-overrun, anti-slip hook, anti-impact, anti-sway, and anti-hanging features. These enhancements are meticulously designed to substantially mitigate on-site safety risks, creating an invincible shield of protection for construction activities. The incorporation of the state-of-the-art ZPI intelligent hoisting system further fortifies operational safety, enabling seamless and efficient task execution, even amidst the demanding challenges posed by super high-rise projects, thereby laying a secure foundation for the successful progression of your construction initiatives. Experience exceptional comfort inside the Zhongtian 7023-12 tower crane's expansive, integrated cab, crafted to withstand moisture, dust, and high temperatures. This thoughtfully designed environment amplifies driver focus and comfort, significantly reducing operational errors prompted by environmental factors, and subsequently enhancing overall work efficiency. Operators continually praise its flawless performance and outstanding driving experience. When it comes to performance capability, this tower crane is truly a powerhouse. Its boom length offers versatility across a diverse range of construction scenarios, with a maximum working extension of 70m, facilitating extensive area coverage. This crane boasts the ability to lift up to 12t with a robust rated torque of 2500KN/m, effortlessly handling a wide array of building materials, from lightweight accessories to more substantial prefabricated components. With an independent lifting height of 60m, a rapid rated lifting speed of 1.33m/s, and a rated lifting height reaching up to 228m, it guarantees swift and efficient material handling, effectively shortening construction timelines. This flat-head tower crane design presents distinct advantages over traditional tower cranes featuring tower heads. It simplifies the lifting requirements during assembly and disassembly, courtesy of its minimal unit mass and reduced installation height. This not only translates into cost savings but also enhances safety and operational speed. When operating in tandem with multiple tower cranes, the height differential can be minimized to a mere 3m, reducing overall height and installation time, demanding less from installation equipment, and minimizing ballast needs. This allows for a more compact tower body and undercarriage while maximizing hook height and space utilization. It is particularly ideal for projects requiring specific height considerations, such as airport renovations, tunnels, factories, and high-voltage environments, excelling in challenging conditions. Furthermore, the innovative boom section connection method facilitates easy and secure assembly and disassembly, adaptable to varied construction demands. The modular boom design ensures that sections from different tower levels within the same series are interchangeable, enhancing applicability and utility. The robust steel boom structure promises longevity and unmatched safety, effectively resisting alternating stresses that could typically cause fatigue damage, fracture, or weld cracking, thus ensuring a reliable and sustainable ally in construction.
