### Core Features
1.  **Heavy-Duty All-Terrain Chassis**: Utilizes a 6-axle all-terrain chassis, providing strong load-bearing capacity and driving stability, with a max speed of 71 km/h and max gradeability of 48%, adapting to complex construction site conditions.
2.  **Super-Long Boom Combination**: The main boom achieves a max lifting height of 65.6 meters. When combined with the 20-meter jib, the max lifting height reaches **85.7 meters**, meeting the hoisting requirements for high-rise buildings and large-span structures.
3.  **Powerful Lifting Performance**: The basic boom generates a high lifting moment of 7797 kN·m, with a 240-ton rated capacity covering the installation of various heavy equipment.
4.  **High Operational Efficiency**: The max speeds for both main and auxiliary hoist ropes exceed 115 m/min. Coupled with a stable slewing system, it effectively enhances lifting operation efficiency.

It should be noted that the QY240 is an all-terrain crane in the 100-ton-plus class, and its chassis structure and application scenarios differ significantly from the 25-ton class models you previously focused o
