Zoomlion QY25V531.5

The QY25V531.5 from Zoomlion is a modern, high-efficiency truck crane developed with the company’s deep experience in mobile lifting technology. Rated for a maximum lifting capacity of 25 tons, it features a main boom measuring from 10.3 meters to 38.7 meters, constructed from low-alloy high-strength steel to balance lightness with structural rigidity. An optional 8.0-meter jib can be attached, extending the crane’s total lifting height to 46.58 meters.

It offers a maximum load moment of 950 kN·m at the base boom and 525 kN·m when the main boom is fully extended, indicating strong lifting capabilities across a range of working radii. The crane’s operational efficiency is enhanced with hoisting speeds of 135 m/min for the main winch and 100 m/min for the auxiliary winch, paired with a slewing speed of 2.6 rpm, ensuring quick load handling and placement.

The boom derricking time is 45 seconds, and telescoping takes 120 seconds, optimizing cycle times on the jobsite. Designed for travel and jobsite mobility, the QY25V531.5 reaches a top road speed of 72.34 km/h and can negotiate gradients of up to 20%, making it capable on highways and rougher site conditions.

It is mounted on the ZLJ5323JQZV3 custom 3-axle chassis, powered by a Weichai WP6.240 diesel engine delivering 176 kW at 2300 rpm and a maximum torque of 900 Nm between 1400 to 1600 rpm. The crane complies with China’s National Stage III emissions standards and demonstrates an oil consumption of approximately 38 liters per 100 km.

For stability, the outrigger footprint spans 5.15 meters longitudinally and 6.1 meters transversely. The minimum ground clearance is 235 mm, and the overall dimensions of the machine are 12.51 meters in length, 2.5 meters in width, and 3.455 meters in height, allowing it to remain transport-friendly while maintaining a low center of gravity for better on-road stability.

The Zoomlion QY25V531.5 truck crane offers an excellent balance of lifting power, operational speed, and mobility—ideal for applications in urban construction, industrial lifting, and medium-scale infrastructure development.
