In terms of safety performance, the Second-Hand Flat-Head Tower Crane with 55kw Lifting Mechanism, supplied by Hebei Borsese Trading Co., Ltd., is an epitome of engineering safety and innovation. It boasts an array of advanced safety modules including anti-overrun, anti-slip hook, anti-impact, anti-sway, and anti-hanging features. These state-of-the-art safety systems substantially minimize risks, forging a robust safety perimeter during construction operations. Complementing these is the ZPI intelligent hoisting system, a testament to technology's role in enhancing operational safety. These configurations enable the tower crane to execute lifting tasks in super high-rise projects with unparalleled stability and efficiency, thereby bolstering the project's overall safety profile. When it comes to driver comfort and operational experience, the Zhongtian 7023-12 tower crane, a key player in this scenario, features a spacious, integrated cab. This cabin is engineered to withstand moisture, dust, and high temperatures, offering an expansive and ergonomic workspace. Such thoughtful design ensures maximum driver concentration and significantly reduces errors, thereby boosting operational efficiency and overall productivity. Feedback from operators highlights the crane's smooth operation and exceptional driving experience, affirming its user-centric design. Regarding its performance metrics, the tower crane features a versatile boom length that adapts seamlessly to diverse construction scenarios, with a formidable working range extending up to 70m. It confidently handles a maximum lifting weight of 12t and boasts a rated torque of 2500KN/m, accommodating anything from light building accessories to hefty prefabricated components with ease. With an independent lifting height of 60m, a rated lifting speed of 1.33m/s, and a remarkable rated lifting height of 228m, this crane accelerates material handling, effectively reducing the construction timeline. The flat-head tower design presents distinct advantages over traditional models with tower heads, significantly lowering disassembly and assembly equipment lifting requirements. Its compact unit mass and minimized installation height can decrease the maximum height by over 10m compared to other cranes in its class, cutting costs and enhancing safety and speed. In operations involving multiple cranes, the intersecting height difference can be reduced to just 3m, promoting efficient space utilization, especially in environments with special height constraints like airports, tunnels, factories, and high-voltage areas. The ingenious boom connection method allows for seamless sectional disassembly and assembly, even in confined spaces where truck cranes are inaccessible. The boom, constructed for longevity and safety, is resistant to alternating stress, drastically reducing the likelihood of fatigue damage or structural failure. This modular design enables interchangeable use of boom sections across different levels in the same series, enhancing the boom's applicability and utilization.
