In the realm of safety, this proficient second-hand tower crane by Hebei Borsese Trading Co., Ltd. is exceptionally equipped with advanced safety hoisting mechanisms. Features such as anti-overrun, anti-slip hook, anti-impact, anti-sway, and anti-hanging ensure a robust safety shield during construction, minimizing potential risks and safeguarding your project. The introduction of the ZPI intelligent hoisting system further enhances operational safety with cutting-edge technology. In super high-rise construction projects, this tower crane excels, executing lifting tasks with stability and efficiency, thus fortifying the project's safe progression. For the operator's experience, the Zhongtian 7023-12 tower crane boasts a spacious integrated cab designed to withstand moisture, dust, and high temperatures. This creates a comfortable and expansive environment for operators, helping to boost concentration and comfort, thus significantly reducing operational errors linked to external factors and enhancing overall work efficiency. Operators consistently commend the crane for its smooth operation and superior driving experience. Performance-wise, the crane's boom length is versatile, adapting to diverse construction needs. With a maximum working range of 70m, it efficiently covers extensive construction areas. Capable of lifting up to 12t, with a rated torque of 2500KN/m, it handles various building materials effortlessly, from light accessories to heavier prefabricated components. Its independent lifting height reaches 60m, with a rated lifting speed of 1.33m/s and a rated lifting height of 228m, ensuring swift material handling and significant reduction in construction time. The flat-head tower design presents unique advantages over traditional cranes with tower heads. It demands lower lifting capacity during assembly and disassembly, with a reduced unit mass and lower installation height. This design cuts the maximum installation height by over 10m compared to other cranes, saving on costs and enhancing safety and speed. When multiple cranes operate in tandem, the height difference between intersecting cranes is minimized to 3m. Overall, this decreases height, reduces installation time, and lessens equipment demands while enhancing hook height effectiveness and spatial efficiency, ideal for special height projects such as airport renovations, tunnels, factories, and under high-voltage lines. The crane's boom sections, devoid of a tower head and tie rods, allow for easy and secure disassembly and assembly. The boom's length can be adjusted in mid-air to suit various project needs, and if the site restricts access for truck cranes, its unique connection method facilitates sectional disassembly and assembly in mid-air, easing the overall process. The boom's steel structure promises longevity and high safety, resistant to vertical and horizontal stress, mitigating risks of fatigue damage or cracking. Its modular design allows for compatibility across different flat-head tower levels, enhancing boom applicability and utilization.
