Hitachi-Sumitomo SCX550

The Hitachi-Sumitomo SCX550 is a reliable crawler crane built for medium-duty lifting tasks, offering a maximum lifting capacity of 55 tons at a 3.7-meter working radius. The crane’s boom system starts with a basic length of 10 meters, extendable to a maximum of 32 meters, allowing for flexible lifting capabilities to meet a range of project requirements.

The SCX550’s winch system is optimized for efficient operation. The main and auxiliary hoist drums offer line speeds of 110 meters per minute, with lower speeds of 74 meters per minute and a low-speed mode of 37 meters per minute, providing adaptable control during lifting tasks. The boom hoist drum has a speed of 60 meters per minute, enabling smooth and controlled boom adjustments.

With a swing speed of 3.7 rpm, the crane ensures precise and stable rotational movements for accurate load positioning. The crane’s travel speed ranges from 2.0 km/h in high mode to 1.5 km/h in low mode, making it suitable for moving efficiently across job sites. The SCX550 has a gradeability of 40%, allowing it to operate on sloped or uneven surfaces with a high level of stability.

Powering the SCX550 is a 147 kW Isuzu 4HK1X engine, which provides the necessary power for lifting operations while maintaining fuel efficiency. The engine’s performance supports the crane’s operational needs, including demanding tasks in construction and industrial settings. The ground contact pressure is rated at 71.9 kPa, ensuring stability and minimizing ground impact during operation.

The crane’s operating weight is approximately 52.5 tons, including a 10-meter boom and 55-ton capacity hook, which ensures a stable base for lifting operations. The SCX550 is suitable for general construction, infrastructure maintenance, and other medium-scale lifting tasks, combining efficient performance with the versatility to adapt to various project demands.
