The SQZ132A.3 6.3 ton knuckle boom crane is a high-efficiency, space-saving folding boom truck mounted crane, engineered to deliver reliable and precise lifting performance for professional contractors and commercial operators working in tight urban and industrial environments. Boasting a maximum lifting capacity of 6300kg and a rated lifting moment of 12.6 t·m, this compact 6.3T hydraulic knuckle crane balances powerful performance with exceptional maneuverability. With a 400° slewing angle, 2250kg lightweight build, and minimal 1070mm installation footprint, it seamlessly mounts on medium-duty trucks, making it the go-to lifting solution for projects where space is at a premium.
Weighing just 2250kg and requiring only 1070mm of installation space, this compact knuckle boom truck crane easily integrates with most medium-duty trucks, enabling fast deployment in narrow urban streets, confined industrial workshops, and high-rise construction sites with limited access.
Delivering a 6300kg maximum lifting capacity and 12.6 t·m lifting moment, the crane handles heavy loads with consistent reliability. Its 400° slewing system enables smooth, unrestricted rotation, drastically improving operational flexibility in space-constrained work zones.
Equipped with a 28MPa rated hydraulic pressure, 40 L/min recommended flow, and 100L oil tank, the system delivers steady, fast, and precise lifting control, supporting continuous operation for long-duration projects without frequent oil replenishment.
Fabricated from high-strength steel with precision manufacturing, the crane offers superior load-bearing stability and long-term durability. Integrated safety features including overload protection, hydraulic stabilization, and intuitive control systems ensure safe operation and reduce operator fatigue.

This 6.3 ton truck crane is tailored for diverse commercial and industrial scenarios, including:
Urban Construction & Building Maintenance: Ideal for lifting HVAC equipment, construction materials, and structural components in narrow urban streets and high-rise sites, the core use case for this 6.3 ton truck crane for HVAC.
Industrial & Warehouse Operations: Efficiently handles heavy machinery, palletized goods, and materials in factories, warehouses, and logistics hubs, reducing manual labor and boosting workflow efficiency.
Municipal Infrastructure Maintenance: Perfect for street lighting installation, pipeline maintenance, and public works projects, with fast deployment and precise positioning capabilities.
Emergency Rescue & Small Port Operations: Quickly deployed for disaster relief debris lifting, and supports light cargo handling at small river ports and docks.
Park the truck on firm, level ground, fully extend and stabilize outriggers with support pads, confirm all control levers are in neutral, and inspect the surrounding area for overhead obstacles and high-voltage lines (maintain a minimum 10-meter distance).
Always follow the official load chart, never exceed the rated capacity for the current working radius, operate one boom handle at a time, and never leave a suspended load unattended.
Lubricate pivot points, boom slides, and hydraulic cylinder pins after each project; regularly check hydraulic oil levels, inspect hoses for wear, and tighten loose bolts to ensure long-term reliable performance.
