The SQZ20A.2 offers a maximum lifting weight of 5 tons while maintaining a compact installation space of only 1070 mm. Engineered from premium high-strength steel, the reinforced crane base and boom structure deliver an outstanding strength-to-weight ratio. This structural integrity ensures excellent fatigue resistance during heavy-duty cycles. The solid thud of the reinforced base locking into place provides immediate assurance of its build quality. For fleet operators, this translates to maximizing the payload capacity of medium-duty trucks where space utilization is critical, ensuring higher transport efficiency without sacrificing lifting capability.
Equipped with a rated hydraulic pressure of 28 MPa and a recommended flow of 40 L/min, this knuckle boom crane ensures smooth, stable lifting and slewing movements. The optimized high-pressure hydraulic circuit significantly reduces pressure loss and improves response speed, characterized by the quiet hum of the fluid mechanics in action. Operators will notice the precise tactile feedback from the control levers, allowing for millimeter-level accuracy when positioning heavy loads. This thermal and pressure stability guarantees consistent performance during high-frequency, continuous loading cycles, enhancing both operator safety and daily productivity.
With a 400° slewing angle, the crane allows flexible operation on both sides of the truck, significantly reducing the time spent repositioning the vehicle. This wide rotational range is paired with a compact mechanical footprint, making it perfectly suited for confined job sites such as narrow urban construction areas and roadside municipal operations. The smooth slewing mechanism minimizes load swing, ensuring materials are placed exactly where needed with minimal effort, even when working in highly restricted spatial environments.
Manufactured through standardized production processes with precision welding, the crane body provides exceptional structural rigidity. Every unit undergoes strict quality inspection to ensure reliability in harsh outdoor conditions. The exterior features an industrial-grade, visually distinct anti-corrosion coating that resists chipping and environmental wear. You can physically feel the thickness of this protective paint layer, designed specifically to repel moisture and prevent rust. This meticulous surface treatment and heavy-duty steel construction guarantee long-term durability, protecting your investment against the elements and intensive daily use.
The modular design simplifies both initial installation and ongoing daily maintenance. Standardized components and easily accessible hydraulic connections help reduce maintenance downtime. Furthermore, we back this equipment with comprehensive after-sales support, including long-term technical guidance and rapid spare parts availability. This ensures that fleet maintenance teams can perform routine checks swiftly and effectively, making this folding boom truck crane a highly cost-effective and dependable solution for demanding transport operations.

Ideal for loading and unloading heavy pallets, construction materials, and dense machinery components during urban and intercity transportation. The crane's precise hydraulic control allows operators to gently place fragile or awkward loads onto the truck bed, minimizing the risk of cargo damage. Its rapid deployment speeds up turnaround times at busy distribution hubs.
Widely used for lifting steel structures, precast concrete elements, and heavy tools on building sites, bridges, and municipal projects. The high-strength steel boom provides the necessary rigidity to handle heavy materials without dangerous flexing. The crane's stable geometric design absorbs dynamic shock loads, ensuring that sudden weight shifts do not destabilize the carrier vehicle in active work zones.
Suitable for installing commercial generators, HVAC units, and industrial equipment where precise positioning is absolutely required. The smooth micro-movements enabled by the advanced valve system let installation crews align heavy bolt holes and mounting brackets with exact precision, eliminating the need for manual pushing or dangerous physical adjustments.
Commonly applied in streetlight installation, roadside maintenance, and public facility construction. The compact footprint and wide slewing angle allow municipal trucks to operate efficiently on single-lane roads without entirely blocking traffic. The low-noise hydraulic operation is also highly beneficial for early morning or late-night maintenance work in residential neighborhoods.
A: The SQZ20A.2 is suitable for medium-duty trucks with sufficient chassis strength and hydraulic power output, commonly 6–10 ton class trucks. The installation space requirement is minimal, allowing plenty of room for the primary cargo box. We provide detailed mounting guidelines to ensure the chassis frame is properly reinforced to handle the torsional stress during heavy lifts, ensuring the vehicle's suspension systems operate safely under full load conditions.
A: Yes, the crane can be equipped with manual valve control or optional remote control systems according to customer requirements. The remote control option offers operators the freedom to move around the load for a better line of sight, significantly improving safety and placement accuracy in cluttered or hazardous environments.
A: Yes, the stable hydraulic system and reinforced structure make it perfectly suitable for high-frequency, long-duration operations. The optimized oil flow prevents excessive heat buildup in the hydraulic reservoir, while the high-strength steel components resist fatigue. Combined with our rapid spare parts supply and dedicated technical support, your fleet will experience maximum uptime even under rigorous daily schedules.
