In addition, different models of QY50K5D cranes may have different configuration details. For example, QY50K5D_1 has a 336-horsepower Weichai National VI engine, a 9-speed gearbox, a double-reduced axle with high-load tires, and a maximum climbing ability of 45%; its upgraded 350L oversized aluminum alloy fuel tank can increase the cruising range by 10%. It uses a sinking H-type double-section outrigger, the industry’s largest 7.5m outrigger lateral span, and has strong anti-deformation ability. Its lifting mechanism is a quantitative pump-variable motor open hydraulic system, a φ18 large-diameter wire rope, and a maximum single rope tension of 50kN.
