Hitachi Sumitomo SCX500W

The Hitachi-Sumitomo SCX500W is a robust 50-ton lattice boom truck crane, engineered for heavy-duty lifting tasks with high precision and safety. Its lattice boom structure provides strength while maintaining a lightweight profile, making it ideal for diverse lifting applications in construction, infrastructure projects, and industrial settings. The crane’s basic boom configuration is 9 meters long, consisting of a 5-meter lower boom and a 4-meter upper boom, providing flexibility and adaptability to a range of operational needs.

One of the key features of the SCX500W is its superstructure, which includes front lights, rearview mirrors, a boom hoist drum check mirror, and an electric refuel device, ensuring that both visibility and convenience are maximized during crane operation. The crane is equipped with a centralized lubrication system for critical components such as the gantry and swing circle, reducing the need for frequent manual maintenance. The counterweight system is a 11.7-ton assembly, providing the necessary balance and stability during lifting operations. A boom hoist speed control system and constant swing speed control system further enhance operational precision, allowing operators to perform tasks smoothly and safely.

The operator’s cabin is designed with both comfort and efficiency in mind. It features intermittent wipers on both the front and roof windows, a rolled sunshade on the roof window, a room light, floor mat, and even a cigarette lighter. These features enhance the overall comfort of the operator during long workdays. The cabin is also equipped with a brake mode selector switch and a work mode selector, both interlocked to ensure that the appropriate settings are used for different lifting tasks. Additionally, the electric tilt-type right-side stand allows for easy adjustment of the operator’s seating position, providing better visibility and control during complex maneuvers.

Safety is a top priority in the SCX500W, with several key systems in place to ensure the protection of both the operator and the crane. The crane is equipped with a swing lock, drum pawl locks on the main and auxiliary hoist systems, and a fail-safe brake system. It also includes overhoist prevention devices for the main hook, boom hoist, and secondary systems, preventing potential operational errors. A moment limiter monitors the load being lifted and ensures that the crane stays within safe working limits. Additionally, a pilot control shut-off lever and before-work check monitor add extra layers of safety, allowing operators to perform essential pre-operation checks easily.

The SCX500W comes with a variety of front attachments to meet specific lifting needs. These include a 50-ton hook with a hook lock for heavy lifting and hoist ropes ranging from 16 mm x 135 meters to 22 mm x 215 meters, ensuring that the crane can handle loads of different weights and sizes efficiently. For specific tasks such as magnet or clamshell lifting, the SCX500W offers purpose-designed attachments. The lifting magnet, for instance, features a boom stop, boom angle indicator, and moment limiter, while the clamshell attachment offers open/close and suspend rope disengagement prevention, making it ideal for digging and material handling tasks.

Overall, the Hitachi-Sumitomo SCX500W is a highly versatile and reliable 50-ton lattice boom truck crane designed to handle a wide variety of lifting applications. Its combination of advanced safety features, comfortable operator cabin, and powerful lifting capabilities makes it an ideal choice for demanding work environments, providing efficiency, precision, and safety across various industries.
