In the competitive realm of construction and industrial lifting, SUNHUNK Straight Boom Cranes stand out as the ultimate powerhouses, combining innovative engineering, rugged durability, and cutting-edge safety features to redefine operational excellence. Designed for professionals who demand nothing but the best, these cranes are engineered to tackle the most daunting tasks with precision and confidence.
The backbone of SUNHUNK Straight Boom Cranes lies in their Q690 high-strength steel plate structural components, a material chosen for its unrivaled balance of extreme strength and lightweight efficiency. This advanced steel construction ensures the crane can withstand heavy loads in challenging environments while reducing overall weight, enhancing mobility and lowering transportation costs. Whether working on skyscrapers or remote infrastructure projects, the robust frame provides unshakable stability, making light work of heavy-duty lifting.
The crane’s enhanced hexagon boom structure is a testament to SUNHUNK’s commitment to innovation. Compared to conventional designs, this breakthrough structure delivers a 20% stronger lifting capacity while ensuring smooth, stable telescoping. The result? Reduced sway during operation, improved load control, and the ability to handle heavier payloads with ease. Whether extending to full height or retracting for tight spaces, the boom’s precision engineering guarantees reliability and safety at every stage.
Equipped with an imported three-stage cylinder and rigging telescoping mechanism, SUNHUNK cranes offer seamless sequential extension for ultimate flexibility. The first two telescoping arms are driven by independent cylinders, empowering medium and short arms with exceptional load-bearing capabilities. This design allows operators to adapt swiftly to changing project requirements, from short-range heavy lifts to extended-reach operations over obstacles. No job is too complex for this versatile, high-performance system.
With an impressive 18.8-meter maximum operating range—the largest in its tonnage class—SUNHUNK Straight Boom Cranes excel at overcoming spatial challenges. This extended reach minimizes the need for frequent repositioning, saving valuable time on high-rise construction, bridge projects, and rescue operations. The crane’s strong cross-obstacle capabilities ensure it can lift materials over barriers and reach tight, hard-to-access areas, making it an indispensable asset for complex job sites.
Safety is paramount in every SUNHUNK design. The standard torque limiter (with override function) provides real-time load monitoring, preventing overloading and ensuring compliance with safety protocols. Additionally, high-pressure filters in the hydraulic system maintain oil cleanliness, extending component lifespan and reducing maintenance downtime. For projects in extreme climates, the crane’s main moving parts and electrical/hydraulic components operate flawlessly at -40°C, ensuring year-round performance in even the harshest cold environments.
