Feature Category |
Core Advantage |
Detailed Description & Technical Highlights |
Efficiency & Stability |
True Horizontal Load Movement |
The hook moves in a near-horizontal path during luffing, eliminating constant height adjustments. This simplifies operation, increases handling efficiency by over 20%, and prevents cargo swing for enhanced safety. |
Structural Integrity & Durability |
Exceptional Overall Stability & Rigidity |
The rigid connection between the boom, jib, tie-rod, and balance lever forms a robust truss system. It ensures even load distribution, minimal deformation, and high wind resistance for stable operation even at a 33m reach, extending service life by approx. 30%. |
Operational Cost & Eco-Friendliness |
Low Luffing Power Consumption |
The large balance lever counterweights the boom's weight. The luffing mechanism only overcomes the net load, reducing required drive power by up to 40% for energy-efficient operation and reduced grid impact. |
Operational Safety & Precision |
Unobstructed Operator Visibility |
The linkage design provides the operator with a wide, clear view of the hook and landing area, significantly improving handling precision and situational awareness, leading to a notable reduction in accidents. |
Versatility & Reliability |
Powerful & Adaptive Lifting Performance |
Delivers full 16-ton capacity across its working range. Suitable for bulk, general cargo, and containers. Engineered for reliable, high-intensity 24/7 operation, with a Mean Time Between Failures (MTBF) exceeding industry standards. |
