Articulated Crane Truck

The articulated crane truck consists of three core components: the truck chassis, the articulated (knuckle boom) crane, and the cargo body. Compared with telescopic boom crane trucks, the articulated design offers a more compact structure and higher working efficiency, making it especially suitable for confined spaces such as warehouses, factories, and narrow urban streets.

1. Chassis System

The chassis is reinforced with a heavy-duty frame to withstand the torsional stress during crane operations. Premium models feature a three-layer through-frame design that reduces integrated component weight by 30%, with a dedicated front suspension capacity of up to 9 tons.

2. Powertrain

Equipped with high-torque diesel engines delivering up to 1800 N·m, with a 30% improvement in transient throttle response for faster acceleration and higher operational efficiency. The dedicated PTO (Power Take-Off, e.g., HW70) enables neutral-gear PTO engagement and external start/stop control, reducing fuel consumption during low-speed operations and ensuring hydraulic system stability.

3. Articulated Crane

• Ultra-High Tensile Steel: Reduces crane weight while maintaining high lifting capacity, increasing payload
• Compact Mounting Space: As low as 1148mm, maximizing cargo body layout flexibility

• Over-Bending Capability: Working angle between main and outer boom ≥195° for flexible operation in narrow passages and under overhead obstructions

• Built-in Telescopic Pulley Design: Maximizes pulley diameter for improved load-bearing telescoping performance, protecting wire ropes and extending service life

4. Hydraulic System

Core hydraulic components are sourced from reputable brands for reliability. All load-bearing cylinders are equipped with load-holding valves to prevent unintended lowering. The extension system features a regeneration valve for faster working speeds.

5. Safety System

• RCL 5300 Rated Capacity Limiter: Real-time load moment monitoring; automatically warns and interrupts unsafe functions in overload conditions while allowing load-reducing operations

• Dual-circuit Hydraulic Locks: Prevents sudden boom drops in case of hydraulic line failure

• Disc-spring Slewing Brake: Stable and reliable braking with high torque output, effectively absorbing inertia during rapid stops
