Product Description
SQZ325 hydraulic folding boom crane is a newly upgraded articulated loader crane, optimized for urban and narrow working environments. Adopting high-strength integral steel boom with hexagonal cross-section structure, the crane features strong torsion resistance and structural stability during heavy-load operation. The unique 15° reverse angle design of inner and outer boom adapts to various low-height working conditions that telescopic cranes cannot handle.
Equipped with dual rack cylinder driving system, the SQZ325 achieves smooth, steady and precise slewing and boom movement with low vibration and high positioning accuracy. The full 360° continuous rotation design eliminates operation dead angles, greatly improving working flexibility in narrow streets, indoor warehouses and dense construction sites. Matched with dual-span outriggers, the whole machine owns ultra-high overall stability during full-load lifting.
This folding boom crane supports flexible installation on multiple mainstream truck chassis. It is equipped with mature hydraulic components and standardized circuit design, featuring low failure rate and convenient daily maintenance. Optional wireless remote control, multi-functional grabbing accessories and customized configurations can meet diversified commercial and engineering lifting demands for global customers.
Product Advantages
Professional Folding Boom Structure:
Articulated folding arm design saves vehicle top space, no height limit for driving, perfectly adapting to low-clearance and narrow working sites such as urban roads and indoor warehouses.
Superior Structural Stability:
High-rigidity hexagonal boom section and precision welding technology enhance anti-bending and anti-torsion capacity, ensuring stable operation under full load.
Dual Rack Cylinder Drive System:
