Zoomlion QAY300

The Zoomlion QAY300 is a high-capacity mobile crane with a maximum rated lifting capacity of 300,000 kg (300 tons). It is engineered to handle demanding lifting tasks with a combination of strength, reach, and mobility. The crane’s main boom can extend up to 80 meters, offering substantial vertical reach for various construction and industrial projects. Additionally, it can be equipped with a jib that extends between 12 and 28 meters, enhancing its versatility for more complex lifting operations where extra reach is required.

In terms of performance, the QAY300 boasts a maximum load moment of 8750 kNm, providing strong lifting capability even at extended distances. The main winch hoist rope speed is 113 meters per minute, with an auxiliary winch capable of 56 meters per minute, ensuring efficient and swift lifting operations. The crane can rotate smoothly with a slewing speed range of 0 to 1.3 revolutions per minute, providing precise control during operations.

The QAY300 is mounted on a 7-axle chassis, which supports a maximum driving speed of 72 km/h, enabling quick relocation between sites. Its gradeability of 50% ensures that it can handle steep inclines, making it suitable for various terrains. The crane’s turning diameter is 24 meters, allowing for maneuverability in constrained spaces, while the ground clearance of 355 mm helps it navigate uneven terrain.

Powering the QAY300 is an OM502LA engine with a rated output of 420 kW at 1800 rpm and a maximum torque of 2700 Nm at 1080 rpm. This robust engine provides reliable performance, conforming to national Stage III emissions standards. The crane consumes approximately 95 liters of fuel per 100 kilometers, which is efficient for its size and capability.

The dimensions of the Zoomlion QAY300 are 17,752 mm in length, 3,000 mm in width, and 4,000 mm in height, making it a substantial piece of equipment that offers stability during operations. For additional support during lifts, it has an outrigger spread of 8.8 meters both lengthwise and widthwise, ensuring a stable base. The crane also offers boom angles ranging from -0.6° to 82°, which adds to the operational flexibility, especially in confined job sites.

Overall, the Zoomlion QAY300 is a robust, versatile, and efficient mobile crane suitable for heavy lifting tasks in construction, infrastructure, and industrial applications. Its powerful engine, extended reach, and adaptable configuration options make it an ideal choice for projects that demand both strength and flexibility.
