Hitachi-Sumitomo SCX1200HD

The Hitachi-Sumitomo SCX1200HD is a heavy-duty crawler crane with a maximum lifting capacity of 120 tons, making it a formidable choice for large-scale construction and lifting projects. The crane’s basic boom length starts at 15.25 meters, and it can be extended to a maximum length of 73.15 meters, providing significant reach and flexibility for handling a variety of tasks at different heights.

The crane’s rope line system ensures efficient load handling. The front and rear drum offers a maximum rope speed of 95 meters per minute, while the boom hoist drum speed is set at 51 meters per minute. Additionally, the third drum operates at 59 meters per minute, allowing for simultaneous operations when required. These rope speeds make it suitable for handling large, heavy loads with precision and efficiency.

With a maximum slewing speed of 2.1 revolutions per minute (rpm), the SCX1200HD provides smooth and controlled 360-degree rotation, ensuring precise positioning of loads. The crane also offers a variable travel speed, with a maximum of 1.5 km/h in high mode and 1.1 km/h in low mode, enabling it to maneuver easily on job sites. The gradeability of the crane is rated at 30%, which allows it to handle inclined surfaces and challenging terrains effectively.

Powering the SCX1200HD is the reliable Isuzu BB-6WG1X diesel engine. This engine is a four-cycle, water-cooled, direct-injection type, equipped with a turbocharger and intercooler, ensuring efficient combustion and performance under heavy load conditions. The engine produces a rated power output of 353 kW, with a maximum torque of 1893 Nm, providing the necessary power for demanding lifting and moving operations.

The SCX1200HD has a ground contact pressure of approximately 86 kPa when using the basic boom configuration, ensuring stability and minimizing soil disturbance during operations. The operating weight of the crane with the basic boom is around 120 tons, which offers a strong and stable base for handling heavy loads.

Overall, the Hitachi-Sumitomo SCX1200HD is a highly capable crawler crane designed for challenging lifting tasks in construction, infrastructure, and heavy industry. Its combination of power, reach, and operational efficiency makes it a reliable and effective tool for large-scale projects.
