Product Advantage
1. Straight Boom Design for Extended Reach
The telescopic boom structure allows smooth extension and retraction, making the SQS125G-5 especially suitable for operations requiring vertical lifting and higher working reach, such as building maintenance and material placement at height.
2. Stable and Efficient Lifting Performance
With a maximum lifting weight of 5,000kg and a lifting torque of 12.5 t.m, the crane delivers reliable performance for daily lifting tasks. The 360° slewing angle improves flexibility and working efficiency without frequent vehicle repositioning.
3. Energy-Efficient Hydraulic System
Operating at a rated hydraulic pressure of 20MPa with a recommended flow of 40 L/min, the hydraulic system ensures smooth control, low energy consumption, and stable operation. The 90L oil tank supports continuous work with minimal downtime.
4. Compact Installation and Excellent Mobility
Requiring only 900mm installation space, the SQS125G-5 is ideal for light and medium-duty truck platforms. Its compact footprint allows easy access to narrow streets, urban sites, and confined working areas.
5. Simple Operation and High Reliability
The straightforward telescopic boom structure reduces mechanical complexity, resulting in easier operation, lower maintenance costs, and long-term reliability, especially for customers seeking a practical and durable lifting solution.

Product Advantage
1. Heavy-Duty Lifting Power for Complex Operations
With a maximum lifting weight of 14,000kg and a lifting torque of 30 t.m, the SQZ300A.4 is designed for demanding lifting jobs such as steel structures, heavy machinery, and prefabricated components. It is an ideal solution for customers seeking a high-capacity truck-mounted crane with superior performance.
2. Optimized Hydraulic Performance and Efficiency
The crane operates at a rated hydraulic pressure of 28MPa with a recommended hydraulic flow of 60 L/min, delivering smooth, precise, and responsive lifting control. The large 180L oil tank supports extended working cycles, reducing downtime during continuous operations.
3. Stable 360° Slewing and Flexible Boom Design
The full 360° slewing angle allows operators to position loads accurately without repositioning the truck. The folding boom structure enhances flexibility, making the crane effective in both open construction sites and space-restricted industrial areas.
4. Compact Installation for High-Capacity Class
Despite its high lifting capacity, the SQZ300A.4 requires only 1,300mm installation space and has a self-weight of 4,450kg. This balance of strength and compactness enables installation on suitable heavy-duty trucks while maintaining good road adaptability.
5. Industrial-Grade Durability and Safety Assurance
Manufactured with high-strength steel and advanced welding technology, the SQZ300A.4 is built for long service life. Integrated safety systems such as overload protection and hydraulic stabilization ensure safe, reliable lifting in high-intensity work environments.
