Jingcheng Heavy Industry has successfully developed a 160-ton all-terrain crane

The 160-ton all-terrain crane QAY160E developed by Beijing Jingcheng Heavy Industry Machinery Co., Ltd. has successfully gone offline. It is understood that the chassis axle of the crane adopts the oil-gas suspension technology, which can balance the axle load of multiple axles, and can automatically adjust the frame according to the unevenness of the road surface; achieving variable stiffness makes the shock absorption effect of the chassis obvious and improves the comfort of the occupants; According to the need to increase or reduce the height of the frame to improve driving performance and ability to reduce the height and center of gravity of the whole machine when driving at high speed; the left and right through and front and back through of the oil and gas suspension cylinder can increase the roll and forward stiffness respectively, avoiding Tilting and braking nod when the vehicle turns.
QAY160E all-terrain crane chassis drive form 10 × 8 × 10, using 4-axis drive, 5-axis all-wheel steering program. The four-axis drive function makes the climbing ability and off-roadability stronger; the electro-hydraulic control multiple steering modes can realize functions such as turning in place and turning crabs, which enhances the flexibility of the machine's transition. Emergency steering and tire centering devices are provided in the steering system. Improved driving safety and high speed stability.
