Zoomlion ZCC12500

The Zoomlion ZCC12500 crawler crane is a powerful heavy-lift machine with a maximum lifting capacity of 1,250 tons, catering to the most demanding construction and industrial applications. With a maximum lifting moment of 16,000 t·m, this crane is engineered for extraordinary performance in large-scale projects, such as wind turbine installations, bridge construction, and petrochemical plant maintenance. It features versatile boom configurations that enable users to optimize the crane setup for different lifting scenarios.

The crane’s boom configurations include the following options:

1. S/SL Boom Configuration: The crane offers a standard (S) boom length from 30 to 84 meters and a superlift (SL) boom extension that can reach 102 meters. This configuration provides a lifting capacity of up to 840 tons at a 7-meter radius, making it ideal for heavy-duty tasks.
2. SDB/SLDB Boom Configuration: With the addition of derrick booms (D) and suspended ballast (B), the crane can achieve an extended SL boom length of 150 meters, with an S-boom length ranging from 42 to 102 meters. This setup significantly enhances stability and lifting capacity, reaching up to 1,250 tons at an 11-meter radius.
3. SFvDB Boom Configuration: This configuration is designed specifically for lifting containers, featuring an S-boom range of 48 to 96 meters and an 18-meter fixed jib (Fv-jib) at angles of 12° or 20°, offering a maximum lifting capacity of 650 tons at a 22-meter radius.
4. SW Boom Configuration: For specialized lifting operations like wind turbine assembly, the SW configuration includes an S-boom range of 42 to 54 meters and a W-jib length between 30 and 90 meters. This configuration allows for boom angles of 65°, 75°, and 85°, providing flexibility in different lifting conditions.
5. Luffing Jib Configuration: The crane includes options for luffing jib struts, with lengths of 21 and 20 meters for strut 1 and strut 2, respectively, to facilitate luffing jib operations.

The ZCC12500’s hoisting system is highly capable, with the primary hoisting winches (H1, H2) offering a single rope speed of 133 m/min and a single rope force of up to 230 kN. The main derricking winch provides a rope speed of 55 m/min with a force of 226 kN. The crane is also equipped with specialized winches for superlift and luffing jib configurations, ensuring optimal performance across different setups.

The crane is powered by a QSK23-C860 engine, delivering 641 kW of power at 2,100 rpm and a peak torque of 3,776 Nm at 1,400 rpm, meeting the demands of heavy lifting operations. It features a slewing speed of 1.0 rpm and a maximum travel speed of 1.0 km/h, providing precise positioning capabilities. With a gradeability of 20%, the ZCC12500 can navigate challenging site conditions, while its ground pressure of 0.153 MPa ensures stable operation on various terrains.

The crane’s transport logistics are optimized with a maximum transport weight of the basic machine at 47 tons and a total deadweight of 790 tons with the basic boom. The modular design allows for disassembly and efficient transport to project sites. The rear counterweight is 250 tons, complemented by a central counterweight of 70 tons, providing excellent balance during lifts.

In summary, the Zoomlion ZCC12500 offers an advanced heavy lifting solution with multiple boom configurations, powerful winching capabilities, and reliable performance, making it suitable for the most challenging lifting tasks in modern construction and industrial projects.
