中联重科 ZAT220

The Zoomlion ZAT220 series is a 220-ton class all-terrain crane, designed for heavy-duty lifting tasks in complex construction scenarios. It integrates advanced engineering for high performance, mobility, and operational efficiency. Core Specifications Maximum Rated Lifting Capacity: 220 tons Boom Configuration: 7 or 8-section telescopic boom, with a maximum extended length of up to 88 meters (ZAT220V8). When paired with a jib, the maximum lifting height can reach 109.6 meters. Max Lifting Moment: Up to 768 t·m (ZAT220H763), delivering strong load-bearing performance at short radii. Chassis & Mobility: Multi-axle chassis (typically 7 or 8 axles) with a top speed of 75 km/h and a maximum gradeability of 40%, enabling smooth travel on both highways and rough construction sites. Counterweight System: Configurable counterweight (up to 90 tons for full configuration), with options to carry partial counterweight for more economical transportation. Key Features High Lifting Height & Reach: The extended boom and jib system make it ideal for wind turbine installation, high-rise steel structure construction, and large industrial equipment hoisting. Stability & Precision: Equipped with single-cylinder pin telescopic technology and advanced hydraulic control systems, ensuring smooth and accurate boom extension and load positioning. Intelligent Operation: Features one-click power take-off and active control strategies, simplifying operation and reducing driver workload. Transport Efficiency: Modular counterweight design allows partial counterweight to be carried on the crane itself, minimizing the number of auxiliary transport vehicles required for job site transfers. Typical Applications Wind Power Industry: Installation of wind turbine nacelles, hubs, and blades at heights exceeding 100 meters. High-Rise Construction: Lifting heavy steel beams, prefabricated components, and mechanical equipment for skyscrapers. Energy & Petrochemical: Hoisting large-scale pressure vessels, generators, and processing equipment in power plants and refineries. Infrastructure Projects: Bridge construction, heavy machinery replacement, and emergency rescue operations.
