In urban development, road rescue, landscaping, and industrial operations, a straight boom crane needs to blend strength, reach, stability, and adaptability to handle diverse tasks. The SUNHUNK Straight Boom Crane (S2106) excels in every aspect: with a 7600kg rated load, 19t.m rated lifting capacity, and 20.3m max working range, it’s engineered to outperform peers in its class. Its seven core features—from high-strength steel construction to low-temperature resilience—make it the top choice for professionals seeking reliability. Let’s explore why it stands out.

1. Q690 High-Strength Steel Structure: Strong & Lightweight

The S2106’s durability starts with key structural components welded with Q690 high-strength steel plate. This premium steel delivers exceptional strength (supporting its 19t.m lifting capacity) while keeping the crane’s self-weight at just 3500kg—light enough for easy transportation between job sites (e.g., urban construction zones or rural landscaping areas) and maneuvering in tight spaces. Q690 also resists corrosion from outdoor elements, ensuring long-term reliability for road rescue or landscaping tasks. For teams needing power without bulk, the S2106 is a standout Q690 high-strength steel straight boom crane.

2. 4220 N.m Slewing Reducer: Peer-Leading Operational Power

Precise load positioning demands strong torque—and the S2106 delivers with a slewing reducer boasting 4220 N.m rated torque (the highest among peers). This power ensures smooth 360° swing, letting operators position 7600kg loads (like construction materials or landscaping trees) in seconds—critical for tight deadlines in road rescue or urban development. Paired with an 80° maximum elevation angle, it enhances safety by preventing load drift during lifts. For high-efficiency operations, the S2106’s reducer makes it a top-tier 4220 N.m torque industrial lifting crane.

3. Enhanced Hexagon Boom: 20% Stronger Lifting Capacity

The S2106’s enhanced hexagon boom structure sets it apart from conventional designs. It ensures stable telescoping (across 5 boom sections) and delivers 20% stronger lifting capacity than standard hexagon booms—ideal for heavy tasks like hoisting road rescue equipment or mature landscaping trees. The hexagonal shape distributes weight evenly, reducing wear and extending boom life. For teams tackling heavy loads, this boom design makes the S2106 a reliable choice.

4. Imported Three-Stage Cylinder Telescoping: Reliable Load-Bearing

Telescoping performance is critical for versatility—and the S2106 features an imported three-stage cylinder and rigging telescoping system. It extends sequentially, with the first two arms driven by independent cylinders, ensuring medium and short arms have strong load-bearing capabilities. This design maintains stability even at full extension (22.5m maximum lifting height), eliminating jolts that could damage delicate landscaping plants or road rescue gear. The imported components add reliability, minimizing maintenance downtime.

5. 20.3m Maximum Operating Range: Industry-Leading Cross-Obstacle Capability

Reaching over obstacles (walls, road barriers, or landscaping features) is effortless with the S2106’s 20.3m maximum operating range—the largest in its tonnage class. This extended reach lets operators handle tasks like road rescue debris removal over barriers or landscaping tree planting in deep green belts, reducing the need to reposition the crane. With a 6300mm support leg spread (corrected from original 63mm for accuracy) ensuring stability, it excels in complex job sites. As a leading 20.3m operating range straight boom crane, it turns obstacles into manageable tasks.

6. Double-Stage Legs (5.8m Span): Superior Stability

Stability is non-negotiable for lifting—and the S2106 comes standard with double-stage legs boasting a 5.8m span. This wide base distributes weight evenly, even when lifting 7600kg loads or operating on uneven terrain (e.g., road rescue sites or rural landscaping areas). The double-stage design adjusts to different heights, keeping the crane level for precise load positioning. For safe, consistent lifts, this feature is indispensable.

7. -40°C Low-Temperature Adaptability: All-Season Reliability

The S2106’s main moving parts, electrical, and hydraulic components work seamlessly at -40°C, making it ideal for winter road rescue, cold-climate urban development, or landscaping in northern regions. Unlike standard cranes that freeze up in extreme cold, it maintains smooth operation year-round, eliminating seasonal downtime. For teams operating in cold environments, this adaptability makes the S2106 a trusted -40°C cold-resistant heavy-duty crane.
