Product Description
🟠 The XCMG QAY300 all-terrain crane represents the pinnacle of heavy lifting technology, designed to tackle the most demanding construction challenges with unmatched versatility and reliability. This 300-ton capacity crane features a robust 7-axle chassis with 5-axle steering and 4-axle drive, providing exceptional maneuverability on both public roads and rough terrain.
🟠 At the heart of the QAY300 is its 7-section elliptical-section main boom (15-80m) with single-cylinder rope-free automatic telescoping system, enabling quick and efficient setup with precise control. The optional superlift device and variable-amplitude jib extend the working range to 86m radius and 116m maximum lifting height, making it suitable for wind turbine installation, bridge construction, and high-rise building projects.
🟠 Powered by dual high-performance engines (Mercedes-Benz for the chassis, Volvo for the upper structure), the QAY300 delivers 405kW (550HP) rated power and 2,700N·m maximum torque, ensuring smooth operation even under full load. The advanced hydraulic system with load-sensing technology provides precise control and energy efficiency, while the computer-integrated control system with fieldbus technology enables intelligent fault diagnosis and automated operation.
🟠 Operator comfort and safety are prioritized with a ROPS/FOPS certified cabin, ergonomic controls, and a 360° panoramic view. The variable-stiffness hydro-pneumatic suspension system ensures a smooth ride, reducing operator fatigue during long transfers. All key components are designed for easy ground-level maintenance, minimizing downtime and operating costs.
🟠 With a maximum travel speed of 72km/h and 50% gradeability, the QAY300 can quickly move between job sites, while the H-type outriggers with independent control provide exceptional stability during lifting operations. Whether working on wind farms, petrochemical plants, or large-scale construction sites, the XCMG QAY300 delivers the power, precision, and reliability needed to get the job done efficiently and safely.
