Product Description
The XGL300-20S 300t·m super-large moment luffing jib tower crane is a professional ultra-heavy engineering lifting equipment customized for high-load, ultra-high-altitude and dense urban complex construction scenarios. The whole machine adopts thickened high-strength low-alloy steel tower sections and integral secondary stress relief welding technology, comprehensively improving structural rigidity, torsion resistance and long-term extreme heavy-load anti-fatigue performance. Compared with 190t·m and lower-spec luffing cranes, the 300t·m ultra-large lifting moment provides explosive power reserve, ensuring zero-jitter stable operation under 20-ton extreme heavy-load and strong wind working conditions.
Equipped with a new generation of full intelligent variable-frequency stepless speed regulation system, the XGL300-20S realizes ultra-smooth and low-impact synchronous control for hoisting, luffing and slewing actions. The upgraded high-power hydraulic matching system outputs continuous and strong torque, supporting frequent cyclic lifting of super-heavy steel trusses, large precast components and heavy construction equipment. The professional vertical zero-tail-swing luffing structure supports 10°–85° wide-angle amplitude adjustment, completely solving the space collision problem of traditional horizontal jib cranes in urban core dense building areas. With high-speed hoisting performance and 805m super-long rope capacity, it fully meets the continuous lifting demands of 268.75m ultra-high-rise super projects.
The whole machine adopts export-oriented standardized modular split design, with regular and unified components, convenient for full-container transportation and greatly reducing cross-border logistics costs. The independent high-efficiency automatic hydraulic climbing system supports rapid layered heightening and on-site fast assembly, greatly shortening the super-project construction cycle. All core electrical, hydraulic and power accessories adopt first-class brand supporting parts, with ultra-low failure rate and super-long service life. In terms of safety configuration, the crane is equipped with a full set of intelligent full-range limit protection systems and emergency braking devices, realizing real-time overload monitoring, wind speed monitoring and tilt early warning. All finished cranes pass strict factory full-load aging tests and extreme working condition simulation to ensure long-term stable and safe ultra-intensity operation.
