XCMG QY25K5

Lifting capacity: The maximum rated lifting weight is 25 tons, and the maximum lifting torque reaches 1137 kN·m. For some models such as QY25K5C_3, the lifting weight of the auxiliary lifting hook is increased to 4.1 tons, which can meet the needs of construction scenarios where the auxiliary lifting hook is used frequently, such as construction sites and elevated bridge construction.

It is equipped with a 43m main boom in five sections and an 8.3m jib. The maximum lifting height can reach 50.1 meters, with multiple boom length combinations, capable of covering various working conditions.

Performance Features

– Power System: Some models are equipped with the Shangchai SC9DF300.1Q5 engine, with a rated power of 221kW, matched with a Fast gearbox and a low-speed, high-torque power transmission system. The maximum speed can reach 90km/h, featuring strong power and low driving fuel consumption.
– Hydraulic System: Adopts proprietary dual-pump automatic confluence and split-flow control technology. When the lifting, luffing, and boom extension actions are performed individually, the dual pumps work in confluence to supply oil, ensuring efficient operation. During compound actions, the dual pumps automatically control confluence and split-flow, enabling compound operations under any working condition with good micro-mobility and smooth operation.
– Energy-Saving Design: Equipped with an ECO energy-saving mode, which intelligently controls the engine speed and oil pump displacement, keeping the engine running in the low-energy-consumption speed range. It can also automatically reduce the engine speed when there is no action for a long time. While increasing the lifting speed by 20% during heavy-load operations, it can effectively reduce fuel consumption.
– Humanized Design: The cab interior has been comprehensively upgraded, including a soft dashboard with a leather-like touch. The high-brightness LED outrigger lights have a 40% increase in brightness and a five-fold increase in service life. The convenient rope-threading system for the lifting hook eliminates the need to disassemble the wedge sleeve, saving 48% of the rope-threading time. The 320L enlarged fuel tank allows for longer cruising range and working hours.
