XCMG QUY300

The XCMG QUY300 is a fully hydraulic crawler crane engineered by XCMG to meet global demand for high-capacity mobile lifting. With a maximum lifting capacity of 300 tonnes and a rated lifting moment of 14,800 kN·m, the crane is suited for critical infrastructure, wind turbine installation, and industrial assembly. It offers several boom configurations: a heavy-duty main boom from 18 to 42 meters, a standard boom from 24 to 72 meters, and a light-duty boom up to 96 meters. These are complemented by a tower jib system ranging from 24 to 60 meters, allowing it to work in close proximity to buildings and tall structures.

The crane’s structure integrates high-tensile German steel tubes for the boom chords, ensuring durability under high loads. Its turntable is a split structure for easier transport and assembly. The crawler frame uses pin-type connections for quick setup, and the wide 1.22 m tracks ensure stability with low ground pressure (0.127 MPa), ideal for rough and soft terrain. It operates with a minimum turning radius and can travel while carrying loads at up to 1.0 km/h with a 30% gradeability.

Powered by a Volvo diesel engine producing 310 kW, the QUY300 employs an electro-proportional, closed-loop hydraulic system with load-sensing for high control precision and operational stability. It features winch speeds up to 100 m/min and slewing at 1.4 rpm. The crane is equipped with a black box, load moment limiter, anti-overturn system, wind speed meter, and electronic safety interlocks through PLC-based controls. The crane also includes self-assembly functionality, reducing dependency on auxiliary cranes during mobilization.

Designed with operator comfort in mind, the cab features wide viewing angles, ergonomic layout, climate control, and multimedia systems. For transport, the crane’s components are modularized, with the heaviest transport unit under 40 tonnes, and overall transport dimensions (main unit) of 11.2 × 3.35 × 3.4 meters.

For specialized applications such as 1.5 MW wind turbine installation, the crane can be fitted with a 7-meter dedicated jib extension in conjunction with a 72-meter main boom, offering a maximum lift of 85 tonnes. The XCMG QUY300 stands out for its lifting capacity, flexible configurations, high reliability, and ease of transport—making it a prime choice in the 300-ton crawler segment.
