Zoomlion ZCC550

The Zoomlion ZCC550 crawler crane is a compact yet powerful lifting machine with a maximum lifting capacity of 55 tons at a lifting radius of 3.7 t·m. It is engineered for medium-duty lifting tasks across various industries, including construction, infrastructure maintenance, and industrial applications. The crane features a versatile boom system, with the main boom extendable from 13 to 52 meters, providing flexibility for different project requirements. Additionally, it can be equipped with a fixed jib, offering lengths from 6 to 15 meters, to further enhance its lifting reach and capabilities.

In terms of configuration, the crane supports several working conditions:

1. S-1 Configuration: Standard boom operation with a boom length of 13 to 52 meters.
2. S-2 Configuration: Combined use of the main boom (25 to 43 meters) with a fixed jib (6 to 15 meters), enabling extended reach.
3. SF-1 and SF-2 Configurations: These configurations involve the fixed jib setup, where the crane can operate with or without the main hook, depending on the lifting requirements.

The ZCC550 is equipped with a reliable WPG6102E engine, which produces 140 kW of power at 1900 rpm and a maximum torque of 830 Nm at 1300 rpm. The engine complies with National Standard II emission standards, balancing performance and environmental considerations. The crane has a maximum slewing speed of 2.1 rpm, allowing for precise maneuvering during lifting operations, while the travel speed reaches up to 1.6 km/h, suitable for repositioning on-site.

The crane’s lifting performance is supported by high rope speeds, with the main lifting winch capable of 120 m/min, auxiliary lifting reaching 120 m/min, and luffing operations at 54 m/min. The adjustable luffing angle from 30° to 80° and fixed jib set angles of 10° or 30° provide flexibility for various lifting scenarios. The ZCC550 also boasts a gradeability of 30%, enabling it to operate on sloped or uneven terrain with confidence.

Transport and setup efficiency are key features of the ZCC550. Its self-weight is 51 tons, with an additional counterweight of 18 tons, ensuring stable operation during lifts. The crane’s overall dimensions of 12,800 mm in length, 4,600 mm in width, and 3,120 mm in height make it compact enough for easy transport. The ground pressure is kept at a low 0.069 MPa, minimizing site impact and allowing the crane to operate on a variety of ground surfaces.

Overall, the Zoomlion ZCC550 crawler crane is a versatile lifting solution for mid-sized projects, combining robust performance, multiple configurations, and efficient transportability. Its design prioritizes adaptability, making it suitable for use in diverse working conditions.
