18 Ton single jib portal crane features high-strength steel structure, 360° full slewing, frequency conversion control and complete safety devices. 港口的理想选择, shipyards and logistics yards, offering stable performance, flexible operation and customized professional after-sales service.
这 18 吨级单臂门式起重机是一种高效, 耐用的, and versatile gantry lifting solution engineered for heavy-duty material handling in ports, 造船厂, 铁路货场, industrial yards, 及物流码头. Adopting a optimized single-jib structural design, this portal crane integrates lifting, luffing, slewing, and traveling functions into one compact and robust unit, balancing outstanding load-bearing capacity, 操作灵活, and stable performance. It delivers reliable 18-ton rated lifting performance, making it an ideal mainstream equipment for medium and heavy cargo loading, 卸货, 和堆叠操作.
Built with a high-strength welded steel framework, the crane’s portal frame and single jib undergo rigorous stress analysis and anti-fatigue testing, ensuring excellent rigidity, seismic resistance, and deformation resistance even under long-term continuous operation. The streamlined single-jib structure features light self-weight, large working outreach, and small horizontal deflection during luffing, effectively improving lifting accuracy and working coverage compared with traditional multi-jib cranes.
Equipped with a full 360° slewing platform and precise four-bar linkage luffing mechanism, the crane realizes smooth, jitter-free angle adjustment and omnidirectional operation without dead zones. The modular mechanical structure simplifies assembly, 拆卸, 以及日常维护, greatly reducing later operation costs. It supports dual working modes of hook lifting and grab handling, enabling flexible adaptation to bulk cargo, container parts, and heavy mechanical equipment handling.
This 18-ton single jib portal crane adopts mature AC frequency conversion speed regulation and PLC intelligent control systems. All operating mechanisms feature stepless speed adjustment, achieving stable start, 精准定位, and smooth stop without impact, which effectively protects cargos and extends the service life of mechanical components. Operators can choose between cabin manual operation and wireless remote control according to on-site working conditions, with simple and humanized operation logic that lowers operational difficulty and improves working efficiency.
The traveling mechanism is equipped with high-precision walking wheels and anti-derailment devices, supporting stable linear movement on standard rails. The matched high-power low-noise motor provides sufficient power reserve, ensuring stable and efficient operation even in harsh working environments such as high wind, 灰尘, 和湿度.
Safety is prioritized in every detail of the crane’s design. It is fully equipped with comprehensive safety protection devices, including overload limiting devices, 高度限制开关, slewing limiters, 紧急停止系统, and wind speed alarm devices. Once the operating parameters exceed the safe range, the system will automatically trigger alarm and power-off protection to avoid equipment failure and safety accidents.
此外, the crane is fitted with anti-slip platforms, protective railings, and professional lighting and communication systems for on-site operation. The whole machine adopts anti-corrosion paint treatment, with excellent rust and weather resistance, adapting to long-term outdoor open-air operation and extending the overall service life of the equipment.
