Dongfeng Truck-Mounted Crane Load Capacity Test | Changxing Crane in Action

Before any crane truck leaves the factory, it goes through rigorous load testing to verify its rated lifting capacity, boom stability, and hydraulic performance under real working conditions. In this video, we put a Dongfeng chassis truck-mounted crane equipped with a Changxing knuckle boom crane through its paces — a full crane capacity test straight from our production facility.

What the Test Covers

The load capacity test is a mandatory quality verification step that confirms the crane performs safely at its rated parameters. Key checkpoints include:

• Rated load lift: Hoisting test weights equal to the crane's rated lifting capacity at specified boom angles and radii.
• Boom extension stability: Full boom extension under load to verify structural rigidity and no abnormal deflection.
• Hydraulic system integrity: Confirming no oil leaks, no pressure drops, and smooth operation of all hydraulic cylinders under load.
• Outrigger performance: All four outriggers fully deployed, leveled, and load-bearing as designed.
• Slewing & luffing under load: 360° slew test and boom luffing to confirm safe control at full rated load.

The Combination: Dongfeng Chassis + Changxing Crane

This unit pairs two trusted names in China's commercial vehicle and lifting equipment industries:

• Dongfeng truck chassis — a proven heavy-duty platform widely used across construction, logistics, and municipal sectors, known for its robust frame and reliable powertrain.
• Changxing knuckle boom crane — engineered for high lifting performance with a compact folded profile, making it ideal for road transport while delivering strong rated capacity on site.

Together, they form a crane truck that meets the demanding requirements of infrastructure, construction, and industrial lifting applications.

Why Factory Load Testing Matters

Every crane truck we supply is tested at the factory before delivery — not just inspected on paper. This means:

• The rated capacity is verified under real load conditions, not theoretical calculations alone.
• Any hydraulic, structural, or control issues are identified and resolved before the machine ships.
• You receive a machine that has already proven its performance, with test documentation available on request.
