The biggest all-terrain crane chassis QAY1600 has just been successfully launched at XCMG, marking a new height of China’s R&D and production ability in super heavy all-terrain crane chassis. QAY1600 is equipped with a self-made 9-bridge system, a high-performance hydro-pneumatic suspension system, and an all-wheel drive multi-mode Electro-Hydraulic Power Steering (EHPS), enabling it to perform pivot-turn and crab hydraulic steering, with higher mobility. The use of multiple-bridge driven technology on QAY1600 provides greater power, making it possible to practice heavy-duty drive and tough-terrain drive, with a maximum climbable gradient of 50%.
