BRIEF

The DONGFENG 8×4 20-Ton Knuckle Boom Crane Truck is a heavy-duty lifting and transportation vehicle equipped with the SQ400ZB5 knuckle boom crane. Built on a robust DONGFENG 8×4 chassis, it combines powerful cargo-carrying capability with advanced hydraulic lifting equipment, making it suitable for demanding material handling and transportation operations.

The SQ400ZB5 crane provides a maximum lifting capacity of 20 tons at 2 meters and a maximum lifting moment of 400 kN·m. Its five-section boom offers a maximum working radius of 13.3 meters and a lifting height of 15.7 meters, while the 360° rotation system allows loads to be lifted and positioned flexibly around the truck. Hydraulic outriggers further enhance stability during heavy lifting operations.

The Knuckle Boom Crane Truck is designed for construction, infrastructure projects, industrial operations, equipment transportation, and heavy cargo loading and unloading. By combining lifting, loading, transportation, and unloading functions in one vehicle, it can reduce the need for additional handling equipment and improve overall job-site efficiency.
