Product Description
The XGL300A-18S is a high-stability luffing tower crane engineered to adapt to diversified and complex construction environments. The entire tower frame adopts integrated high-strength steel fabrication with precision welding and stress elimination treatment, effectively improving structural rigidity, deformation resistance and long-cycle working durability. Compared with smaller-moment luffing cranes, the 300t·m class chassis provides abundant load tolerance, allowing the machine to maintain stable output during repeated heavy-lifting cycles without structural fatigue or jitter.
Equipped with optimized variable-frequency drive technology, the crane realizes graded and smooth speed regulation during hoisting, slewing and luffing movements. The upgraded hydraulic power matching system delivers consistent torque output under variable load conditions, ensuring reliable lifting of large steel frames, precast concrete segments and bulky construction materials. Its professional vertical luffing mechanism adjusts working radius through jib angle variation instead of horizontal trolley movement, greatly reducing lateral space occupation and effectively avoiding interference with surrounding buildings on compact urban sites.
The machine adopts standardized modular assembly design for all main components, making disassembly, container shipping and on-site installation more efficient and cost-saving. The hydraulic self-climbing system enables convenient layered height increment as buildings rise, shortening overall project progress. All core electrical elements, hydraulic valves and power units are sourced from trusted industrial-grade suppliers to reduce failure frequency and extend service life. The built-in multi-dimensional safety monitoring system tracks load amplitude, height, wind speed and operating status in real time, with automatic interlock protection to ensure standardized and safe high-altitude operation throughout the construction cycle.
Product Advantages
Balanced 300t·m Class Working Moment:
Adopts large-moment chassis design with excellent load tolerance, providing stable and reliable lifting performance for frequent heavy-duty construction, far exceeding conventional medium-spec luffing cranes in operational stability.
18-ton Practical Heavy Lifting Capacity:
Matches the mainstream heavy-component lifting demands of modern super projects, realizing efficient heavy-load operation without redundant performance waste, achieving superior cost-performance ratio.
60m Extended Jib & Stable End Load:
Long-span jib design expands effective construction coverage; steady 3.2t tip load guarantees credible far-end lifting capacity, improving overall site working radius and operational flexibility.
Space-saving Zero Tail Swing Structure:
Tail-free vertical luffing design eliminates lateral operating restrictions, enabling flexible construction in dense urban zones, narrow road edges and clustered building sites with zero collision risk.
Hierarchical Height Adaptability:
Reasonable free-standing height reduces early-stage attachment installation workload; expandable maximum attachment height satisfies most high-rise construction scenarios with strong engineering compatibility.
Optimized Variable-frequency Control System:
Smooth and shock-free speed transition minimizes structural vibration and material shaking at height, improving construction accuracy and protecting finished components.
Enhanced Structural Wind Resistance:
Reinforced tower body structure and optimized force distribution enable stable operation under variable wind conditions, suitable for coastal zones and open high-altitude construction environments.
Export-oriented Modular Configuration:
Uniform standardized component sizes adapt to international container transportation, lowering cross-border logistics costs and supporting rapid field assembly in overseas projects.
Multi-dimensional Intelligent Safety Protection:
Integrated limit monitoring, wind speed detection and emergency braking systems form a full-range safety barrier, effectively preventing overload, over-range and abnormal working risks.

FAQ
Q1: How does the XGL300A-18S differ from the standard XGL300-20S model?
A: Both models share the mature 300t·m large-moment platform and 60m jib layout. The XGL300A-18S is tuned for economic heavy-duty work, featuring 18-ton rated load and 199.1m maximum attachment height. In contrast, the XGL300-20S focuses on extreme heavy-load and ultra-high working scenarios. The 300A-18S delivers more balanced cost performance for conventional large-scale projects without ultra-high load and height requirements.
Q2: What working height can the XGL300A-18S support?
A: The machine can operate independently at a free-standing height of 46.1 meters without wall attachments, meeting the construction needs of mid-rise and low super-high buildings. With standard wall attachment systems, the maximum working height can reach 199.1 meters, covering most mainstream high-rise construction scenarios.
Q3: Why choose a luffing jib crane for urban building projects?
A: Luffing jib cranes adjust operating radius through vertical jib angle change instead of horizontal movement. This design greatly saves construction space, avoids jib collision with adjacent buildings, and solves the core difficulty of limited operating space in crowded urban central areas, which flat-top cranes cannot handle efficiently.
Q4: Is the XGL300A-18S suitable for overseas transportation and rapid deployment?
A: Yes. The whole machine adopts modular segmented design with standardized outer dimensions, fully compatible with international container shipping standards. It effectively reduces overseas logistics costs. Meanwhile, the hydraulic self-climbing structure simplifies on-site assembly steps, enabling fast deployment and efficient construction progress acceleration.
Q5: What safety protection configurations are equipped on this crane?
A: The XGL300A-18S is equipped with a complete intelligent safety monitoring system, including torque limit protection, height limit protection, working amplitude limit, real-time wind speed detection and emergency braking function. The system can automatically trigger alarm and power-off protection once abnormal working status occurs, ensuring overall construction safety.
Q6: What types of projects is the XGL300A-18S most suitable for?
A: It is highly adaptable for mid-to-large super high-rise buildings, urban renewal reconstruction, municipal bridge traffic projects and large industrial plant construction. It serves as a cost-effective large-moment heavy-lifting device for medium and high-standard engineering projects pursuing both performance and budget control.
