Product Advantage
1. Heavy Lifting Capability with Exceptional Structural Rigidity
At 14,000 kg maximum lifting capacity and 30 t.m lifting moment, the SQZ300A.3 is designed to handle oversized loads, large-scale components, and heavy machinery with confidence. The crane frame and boom structure are reinforced for high fatigue resistance even in the toughest environments.
2. Powerful Hydraulic System for Continuous High Performance
With recommended power of 35 kW, a 60 L/min hydraulic flow, and 28 MPa rated pressure, this model delivers smooth, responsive, and powerful hydraulic control under heavy load conditions — outperforming many standard supplier cranes in efficiency and load handling.
3. 360° Slewing for Superior Operational Freedom
A full slewing rotation maximizes operational versatility, allowing safe and precise handling of materials on all sides of the truck without frequent repositioning — vital in congested job sites and large infrastructure environments.
4. Reinforced Fatigue-Resistant Boom Design
Compared with many typical competitor cranes, the SQZ300A.3 features a more robust boom with thicker section modulus and optimized welding reinforcement, significantly improving fatigue life and long-term structural integrity.
5. Manufacturer-Level Quality Assurance & Load Accuracy
Built with advanced production technology and strict quality inspection systems, this crane offers consistent load accuracy and safe lifting cycles. Tengchang Construction Machinery’s quality control ensures reliability in even the most demanding industrial applications.
