Key Features and Applications
Specialized Octagonal Boom Design
The QY12KC is equipped with a four-section telescopic boom featuring an octagonal cross-section.[6] This profile, made from high-strength steel, optimizes weight distribution and provides enhanced resistance to bending and torsion, ensuring safety and precision during lifting at significant radii.[2][6]
Efficient Hydraulic and Control System
This crane utilizes a mechanical and valve-controlled hydraulic system with a fixed displacement pump. The winch system features double-pump confluence technology for high lifting efficiency, while the slewing system is equipped with buffering technology for smooth transitions and accurate load positioning.
High-Mobility 2-Axle Chassis
Built on a specialized 2-axle carrier, the QY12KC offers a small turning diameter of approximately 17 meters, making it highly suitable for high-density urban areas. Powered by a 118 kW engine, it reaches road speeds of up to 88 km/h for rapid relocation between project sites.
Integrated Safety Systems
To ensure operational security, the equipment incorporates a mature load limiter system with sensors (often featuring German technology) to prevent overload.[1][2] Real-time monitoring of load data, boom angles, and hydraulic pressure assists the operator in maintaining steady performance throughout the work cycle.
Versatile Utility Applications[5]
-
Urban Infrastructure: Ideal for street lighting maintenance, pipe laying, and sign installation.
-
Municipal Works: Tree trimming, landscaping support, and city greening projects.
-
General Construction: Reliable for light material handling and structural assembly on small job sites.
