Zoomlion ZCC7200

The Zoomlion ZCC7200 is a highly capable crawler crane designed for heavy lifting operations in demanding environments such as construction and energy sectors. With a maximum lifting capacity of 600 tons and a maximum lifting moment of 7,200 ton-meters, the ZCC7200 is engineered to handle significant loads with precision and safety.

Boom and Jib Configurations:

The crane’s boom system is highly flexible, allowing for various configurations to meet different operational requirements. The main boom (in heavy configuration, S mode) can be extended from 24 to 84 meters, and when paired with a derrick boom and suspended ballast (SDB mode), it can reach up to 120 meters. For lighter loads, the boom (SL mode) can extend from 66 to 138 meters when configured with the derrick boom. Additionally, the crane is equipped with a luffing jib (SW mode), offering lengths from 24 to 84 meters, enabling the crane to work effectively in tight spaces or for tasks that require extended reach.

Lifting Performance:

The ZCC7200’s lifting performance is robust across various configurations. For instance, with a maximum heavy main boom length of 120 meters and an appropriate luffing jib, the crane is capable of handling a wide range of tasks, from standard construction to specialized projects like wind turbine installation. The crane’s maximum lifting capacity is 600 tons, making it suitable for large-scale lifting operations.

Mechanisms and Performance:

This crane features advanced hoisting mechanisms driven by variable displacement axial piston hydraulic motors, ensuring smooth and precise control. The primary hoisting winch has a single line speed of up to 135 meters per minute, and the crane’s slewing mechanism provides a controlled rotation speed of up to 1 rpm. The traveling system, powered by four reducers, allows the crane to move at speeds up to 0.8 km/h, with a maximum gradeability of 30%, ensuring stable and efficient operation on various terrains.

Engine and Power:

The ZCC7200 is powered by a 390 kW diesel engine, which complies with Chinese national stage III emission standards. This engine delivers a maximum torque of 2300 Nm at 1400 rpm, ensuring sufficient power for heavy-duty lifting and precise operation under load.

Transport and Setup:

Despite its large size, the ZCC7200 is designed for efficient transport and assembly. Key components like the slewing table and crawler assemblies are modular, with transport dimensions of the basic machine being 13,325 mm in length, 3,400 mm in width, and 3,275 mm in height. This design facilitates easier relocation and setup, making the crane adaptable to various job sites.

Safety and Control Systems:

Safety features on the ZCC7200 are comprehensive, including a load moment limiter that prevents overloading, hydraulic overflow valves, and hoisting height limiters to ensure safe operation. The crane also includes a centralized display system and GPS monitoring for real-time performance tracking and remote diagnostics, enhancing safety and operational efficiency.

In conclusion, the Zoomlion ZCC7200 crawler crane is a powerful and flexible solution for heavy lifting tasks, particularly in construction and energy sectors. With its 600-ton lifting capacity, versatile boom configurations, and advanced safety systems, it is well-suited for large-scale and complex lifting projects.
