High maneuverability XCMG QAY500A Truck crane

84 meter ultra long main arm, covering high-altitude/long-distance core working conditions

The 7-section elliptical main arm has a full extension of 84 meters, and with the addition of optional auxiliary arms, it can reach 145 meters+. The wind turbine tower, bridge erection, and chemical tower hoisting can be completed in one station.
Single cylinder pin+intelligent boom control, smooth extension and contraction, automatic amplitude compensation, and more stable and efficient long arm operation.
Elliptical section high-strength steel arm frame, with strong bending and torsion resistance, and higher load-bearing capacity under the same arm length.

Y-shaped lifting+large counterweight, fully loaded performance

Equipped with a Y-shaped super lifting system and a large counterweight, the lifting performance can be improved by 12% -60%, making high elevation angles and heavy load conditions safer.
Self assembling and disassembling counterweight design, rapid deployment, increased efficiency of transition and positioning by about 50%, saving annual shift and trailer costs.
Large span support legs (10.125 m × 9.6 m)+reinforced slewing bearings, the whole machine has outstanding anti overturning ability, and does not sway or tilt legs under heavy loads.

Eight axle all ground chassis, balancing maneuverability and passability

8-axle chassis+6-axle steering, minimum turning radius of 15 meters, flexible passage on narrow urban roads and construction site access roads.
4-axle drive+high torque power, maximum speed of 80 km/h, fast cross regional transition; 35% maximum climbing slope, making it easy to climb up and down on mountainous construction sites.
Independent suspension+adaptive shock absorption, stable high-speed driving, good off-road passability, and no “arm shaking” on complex road surfaces.

Intelligent hydraulic+integrated control, efficient and easy to open

Electric proportional pump controlled hydraulic+dual pump separation and merging, excellent micro motion (minimum lifting of 2.5 m/min, minimum rotation of 0.1 °/s), precise alignment.
Computer integrated control (fieldbus), one click working condition matching, automatic arm length calculation, real-time fault diagnosis, even beginners can quickly get started.
The maximum speed of the main/auxiliary winch is 170 m/min, leading the industry in lifting speed and shortening the operation cycle.
