Zoomlion ZCC3500V-2

The Zoomlion ZCC3500V-2 is a high-capacity crawler crane engineered for demanding construction and infrastructure projects that require precision, strength, and adaptability. It boasts a rated maximum lifting capacity of 350 tons at a 7-meter working radius and features a maximum load moment of 2,450 t·m in standard configuration, extending up to 2,790 t·m with attached counterweights. This crane is particularly suitable for operations involving shield tunneling equipment, petrochemical assemblies, and high-rise structure erection.

Its modular boom system supports a heavy-duty main boom (S mode) ranging from 24 to 84 meters. It can also be configured with a luffing jib (SW mode) of 24 to 60 meters, allowing for a combined reach of up to 60+60 meters. Fixed jibs are available for shield machine handling, with configurations like 24+9m or 24+12m, supported by enhanced counterweights. The luffing jib mode supports up to 150 tons of lifting capacity, providing operational flexibility across job types.

The crane is powered by a Weichai WP10 engine rated at 247 kW (2000 rpm), with 1600 Nm of torque at 1200–1400 rpm, compliant with China’s Off-road Stage III emission standards. It includes a 750-liter fuel tank for extended operation periods. Hoisting systems feature high-speed winches with variable frequency drives, enabling lifting speeds up to 140 m/min and 130 m/min for the primary and secondary hoisting mechanisms respectively. The boom hoisting winch operates at 40 m/min, while the luffing jib winch reaches 130 m/min.

Its slewing system, with a max speed of 1.0 rpm, incorporates a closed-loop hydraulic circuit for smooth operation and controllable free swing. The travel system supports movement at up to 1.0 km/h with 30% gradeability, and track assemblies are self-installable via an internal hydraulic mechanism, enhancing onsite efficiency. Ground pressure with the main boom setup is 0.146 MPa, and the crane’s total working weight is 305 tons. The maximum single transport unit weighs 49 tons.

Safety features are comprehensive, including a load moment limiter with real-time monitoring, over-winding/unwinding protection, boom angle indicators, derricking limiters, and anemometers. The operator’s cab is ergonomically designed with full-vision glass, air conditioning, a digital interface, and a tiltable structure for overhead work, providing a comfortable and efficient control environment. Optional remote monitoring and GPS diagnostics extend its capabilities for fleet managers.
