In the competitive arena of modern construction and heavy machinery operations, the Straight-Arm Efficiency King stands tall as a symbol of power, precision, and innovation. Engineered to dominate challenging worksites, this crane combines high-strength materials, industry-leading torque, and cutting-edge design to redefine efficiency standards. Whether tackling high-rise projects, infrastructure development, or industrial lifting, this crane is your key to unlocking unmatched productivity.

1. Q690 High-Strength Steel: Lightweight Strength for Heavy-Duty Operations

The foundation of the Straight-Arm Efficiency King lies in its Q690 high-strength steel plate construction, meticulously welded to create a robust yet lightweight framework. This advanced material offers exceptional tensile strength, enabling the crane to withstand rigorous loads while reducing overall weight by up to 20%. The result? Enhanced mobility on congested job sites, lower transportation costs, and prolonged equipment lifespan—all without compromising stability or durability.

2. 6500 N.m Slewing Reducer: Peerless Torque for Unmatched Performance

At the core of this crane’s dominance is a 6500 N.m rated torque slewing reducer—the highest torque output among 同类产品 (peers). This powerhouse component delivers unrivaled rotational force, allowing the crane to maneuver heavy loads with precision, even in tight or complex environments. From hoisting industrial machinery to positioning structural components in high-rise builds, the slewing reducer ensures smooth, reliable operation and minimizes downtime.

3.  Octagon Boom: 15% Higher Capacity with Advanced Lightweight Design

The crane’s octagon boom represents a breakthrough in lifting technology. By optimizing stress distribution through finite element analysis, this design achieves a 15% higher carrying capacity than traditional hexagon booms of the same tonnage, all while maintaining a lightweight profile. The result is reduced material fatigue, improved lifting stability, and the ability to handle heavier payloads with confidence—ideal for projects that demand both power and precision.

4. 19-Meter Operating Range: Extended Reach for Versatile Applications

With a 19-meter maximum operating range—3.5 meters longer than mainstream four-section boom models—the Straight-Arm Efficiency King outperforms competitors in versatility and reach. This extended range eliminates the need for frequent repositioning, making it ideal for 跨越障碍物 (obstacle-crossing) in bridge construction, highway maintenance, or urban infrastructure projects. The ability to access hard-to-reach areas ensures faster project completion and reduced operational costs.

5. Dual Extendable Arms with Cable Lock: 40% Higher Safety Factor

Safety is non-negotiable in heavy lifting, which is why the crane features double extendable arms with a cable lock system. This innovative design provides a 40% higher load extension safety factor than industry standards, ensuring secure and stable lifts even under extreme conditions. The cable lock mechanism enhances control during telescoping, minimizing the risk of accidents and ensuring compliance with the strictest safety regulations.
