◉ Product Introduction

Whether it's loading and unloading construction materials at job sites, handling heavy equipment in industrial yards, or assisting in urban infrastructure projects with limited workspace, the HOWO 6×4&8×4 knuckle boom crane truck delivers outstanding performance with power and precision.


Flatbed box truck mount fold arm crane


Its high-torque engine—available in a range from 340 to 400 HP—provides strong climbing ability and smooth starting under full load, ensuring stable operation even on rugged terrain or tight urban streets. The robust 6×4 drive configuration guarantees excellent traction and adaptability to diverse working environments, from construction sites to logistics hubs.

The knuckle boom crane is engineered with high-strength steel for durability and reliability, featuring a multi-stage hydraulic folding arm that provides exceptional flexibility and reach. With a lifting capacity of up to 43 ton-meters, it enables precise and efficient loading and unloading in confined spaces where traditional straight boom cranes cannot operate.

The reinforced cargo body is built with Q235/Q355 steel to withstand heavy loads and frequent impact, meeting the demands of transporting construction materials, equipment, and goods. The flatbed or dump cargo design offers ample space for cargo, making it a true dual-purpose vehicle for both transport and lifting operations.

The spacious and ergonomically designed cabin offers superior comfort, with optimized seating, vibration reduction, and noise insulation to minimize driver fatigue during long working hours. Large view windows provide excellent visibility for crane operations, while practical storage spaces enhance the driving experience.

Choose the HOWO knuckle boom crane truck for a versatile, powerful, and efficient solution—your trusted partner in lifting and transportation!
