Product Description
The Hitachi-Sumitomo SCX1200-3 is a high-performance crawler crane capable of handling up to 120 tons of load at a 5.0-meter working radius in liftcrane mode, making it ideal for large-scale lifting applications. With a basic boom length of 15 meters, the crane can extend its boom up to a maximum of 75 meters, allowing for a wide range of lifting heights. An additional crane jib, ranging between 10 and 28 meters, can be attached for further reach, providing a combined boom and jib length of up to 91 meters (63 + 28 meters), enhancing its versatility in different project environments.
For luffing towercrane applications, the SCX1200-3 offers tower lengths ranging from 30.35 meters to 51.35 meters, and a tower jib length of 24 to 45 meters, which results in a maximum tower and jib configuration of 96.35 meters. This configuration is ideal for projects requiring precision lifting over tall structures or obstacles, providing both height and flexibility.
The crane’s rope line system ensures efficient handling of heavy loads, with the front and rear main drums offering speeds of 110 meters per minute under a 12-ton load. A third winch, when used in liftcrane mode, operates at 95 meters per minute, while the boom hoist drum runs at 44 meters per minute for smooth boom adjustments. The luffing towercrane configuration includes a tower jib hoist drum with a speed of 55 meters per minute, enabling rapid and efficient positioning of loads at height.
The SCX1200-3 has a swing speed of 1.7 revolutions per minute (rpm), providing controlled and accurate rotational movements during operations. The crane’s travel speed is adjustable between high and low settings—1.5 km/h in high mode and 0.9 km/h in low mode—allowing the machine to traverse job sites efficiently while maintaining stability. With a gradeability of 30%, it can handle various terrains, ensuring reliable performance on slopes and uneven surfaces.
For clamshell operations, the crane features a bucket capacity of 2.5 cubic meters and a maximum digging depth of 36 meters, making it suitable for excavation projects. The clamshell mode also offers a support and opening/closing wire rope speed of 64 meters per minute, ensuring quick and efficient digging cycles.
The crane is powered by an Isuzu 6HK1 engine, compliant with Stage III B / Tier 4 emission standards, generating a rated output of 210 kW at 1,900 rpm. This engine provides ample power for heavy lifting while meeting modern environmental regulations. The operating weight of the SCX1200-3 varies based on configuration, with the liftcrane mode weighing approximately 122 tons (with basic boom and 120-ton hook block), the luffing towercrane mode at approximately 137 tons (with the maximum tower and jib length), and the clamshell mode at around 125 tons (with a 2.5 m³ bucket).
Ground contact pressure ranges from 91 kPa to 102 kPa depending on the configuration, ensuring safe operation on different types of terrain while minimizing soil compaction.
Overall, the Hitachi-Sumitomo SCX1200-3 is a highly versatile and powerful crawler crane, offering exceptional lifting capacity, advanced configurations, and operational flexibility across liftcrane, luffing towercrane, and clamshell applications. Its advanced rope systems, efficient engine, and optimized configurations make it a valuable asset for various construction and engineering projects.
