In construction, logistics, urban maintenance, and landscaping, a knuckle boom crane needs to balance strength, agility, and precision to handle diverse tasks. The SUNHUNK Knuckle Boom Crane (S2006) excels in all areas: with an 8000kg rated load, 20t.m rated lifting capacity, and 18.7m max working range, it’s engineered to outperform peers in its class. Its five core features—from high-strength steel construction to extended operational range—make it the top choice for professionals seeking reliability and efficiency. Let’s explore why it’s a game-changer for modern lifting operations.

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

The S2006’s durability starts with key structural components welded with Q690 high-strength steel plate. This premium steel delivers exceptional strength (supporting its 20t.m lifting capacity) while keeping the crane’s self-weight at 3950kg—light enough for easy transportation and maneuvering in tight spaces (like narrow urban streets or crowded nurseries). Q690 also resists corrosion from outdoor elements, ensuring long-term reliability for landscaping or road rescue tasks. For teams needing power without bulk, the S2006 is a standout Q690 high-strength steel knuckle boom crane.

2. 4400 N.m Slewing Reducer: Peer-Leading Operational Power

Precise load positioning demands strong torque—and the S2006 delivers with a slewing reducer boasting 4400 N.m rated torque (the highest among peers). This power ensures smooth 360° swing, letting operators position 8000kg loads (like construction steel or large planters) in seconds—critical for tight deadlines. Paired with a 75° maximum elevation angle, it enhances safety by preventing load drift during lifts. For high-volume operations or time-sensitive projects, the S2006’s reducer makes it a top-tier 4400 N.m torque slewing reducer crane.

3. Enhanced Hexagon Boom: 20% Stronger Lifting Capacity

The S2006’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 machinery or mature trees. The hexagonal shape distributes weight evenly, reducing wear and extending boom life. For teams tackling heavy loads, this boom design makes the S2006 a reliable enhanced hexagon structure lifting crane.

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

Telescoping performance is critical for versatility—and the S2006 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 (20m maximum lifting height), eliminating jolts that could damage delicate loads (like landscaping plants). For consistent, safe telescoping, the S2006’s system is a key advantage.

5. 18.7m Maximum Operating Range: Industry-Leading Cross-Obstacle Capability

Reaching over obstacles (walls, machinery, or trees) is effortless with the S2006’s 18.7m maximum operating range—the largest in its tonnage class. This extended reach lets operators handle tasks like utility maintenance over barriers or cargo loading from distant spots, reducing the need to reposition the crane. With a 6300mm support leg spread (note: corrected from original 63mm for accuracy) ensuring stability, it excels in complex job sites. As a leading 18.7m operating range knuckle boom crane, it turns obstacles into manageable tasks.

Why Choose SUNHUNK Knuckle Boom Crane (S2006)?
