Key Features and Applications
Knuckle Boom Folding Design
The SQ12ZK3Q utilizes a knuckle (folding) boom design, which provides greater flexibility during loading and unloading operations. The boom can be folded when not in use, significantly reducing the space occupied on the vehicle and allowing for more cargo capacity. This feature is particularly beneficial for urban logistics and construction sites with overhead obstructions.
High Lifting Moment and Stability
With a maximum lifting moment of 30 t.m, this crane is capable of handling substantial loads at varying radii. The structural design ensures stability during heavy lifts, providing reliable performance for industrial cargo handling and heavy equipment relocation.
360-Degree Continuous Rotation
Equipped with a continuous slewing mechanism, the crane offers a full 360-degree rotation. This allows operators to access materials from any direction without needing to move the truck, improving work cycle efficiency and reducing operational time on busy job sites.
Advanced Hydraulic System
The hydraulic system is configured for precision and durability, featuring a rated pressure of 28 MPa and an oil flow of 55 L/min. This setup ensures smooth movements and sensitive control, which are essential for the safe placement of heavy or delicate materials.
Versatile Industrial Use
The SQ12ZK3Q is suitable for a wide range of B2B applications:
-
Logistics and Freight: Rapid loading and delivery of palletized or heavy bulk goods.
-
Municipal Works: Supporting utility repairs, street lighting maintenance, and urban infrastructure projects.
-
Construction Logistics: Moving structural materials and machinery across site locations.
