The QY50K5D-2 truck crane features a 45.5 m main boom and 16 m jib, delivering a maximum lifting height of 61.5 m. Its medium- and long-boom lifting performance is stronger than similar models, with overall efficiency improved by about 5%–10%.
With a compact vehicle height of 3.59 m, the crane can easily access height-restricted construction sites and workshops, offering excellent flexibility for various lifting conditions. The sunken H-type double-section outriggers provide a wide 7.5 m horizontal span, ensuring better stability and safety during long-radius operations.
Equipped with carefully selected core components such as the engine, gearbox, axles, hydraulic and electrical systems, the QY50K5D-2 delivers reliable performance and dependable support for demanding lifting tasks.
