Hitachi-Sumitomo UCX300

The Hitachi-Sumitomo UCX300 is a 30-ton class lattice boom truck crane engineered to meet the needs of medium-scale lifting operations. With a maximum rated capacity of 30 tons at a load radius of 3.0 meters, this crane is well-suited for construction, infrastructure, and industrial applications. The lattice boom design allows for high lifting performance while maintaining a lightweight structure. The boom can be configured with extensions for maximum flexibility, with the longest boom option reaching 24 meters, including 9 meters of basic boom and various extensions. This versatile boom system provides excellent reach and load-handling capability for a wide range of tasks.

The crane’s hydraulic system is powered by two high-efficiency variable displacement axial piston pumps paired with fixed displacement gear pumps. This dual-pump system ensures smooth and precise control over all crane functions, including boom hoisting, swinging, and winching. The hydraulic reservoir has a capacity of 250 liters, ensuring uninterrupted operations. The winch system features a high line pull capacity of up to 107.0 kN, allowing for reliable lifting of heavy loads, and the line speed reaches 57 meters per minute under load. The boom can be elevated at a speed of 13 seconds from a 40° to 60° angle, providing quick adjustments for various lifting scenarios.

The UCX300 is powered by an Isuzu AA-6BG1T engine, a 6-cylinder, 4-cycle, direct injection diesel engine with a turbocharger and intercooler, providing 110 kW (150 PS) of rated power at 2,100 rpm. The engine complies with European and American emission standards (Stage/Tier 2), ensuring that the crane operates efficiently with low environmental impact. The engine’s maximum torque is 549 Nm at 1,600 rpm, offering robust performance for demanding work environments. Fuel efficiency is a key focus, with a consumption rate of 237 g/kW-h and a 360-liter fuel tank to support long operation periods without frequent refueling.

For mobility, the UCX300 features a 4×4 drive system with all wheels engaged when driven by the hydraulic motor. The transmission is a 2-stage hydraulic remote control unit with power shift capabilities, allowing for seamless transitions between high and low speeds. The crane’s top travel speed is 18 km/h in high gear and 4.6 km/h in low gear, making it suitable for transport between job sites and precise movement on-site. The crane has a gradeability of 16.7 degrees, allowing it to traverse slopes and uneven terrain with ease. Its turning radius is 9.9 meters, providing maneuverability in confined spaces.

The crane’s undercarriage is equipped with an oscillating pivot axle and a center-pivot mechanism for smooth ride performance. The tires are 11.00-20, 18 PR, which offer durability and traction in various conditions. The UCX300 is also equipped with hydraulic wet-disc brakes on all four wheels, ensuring reliable stopping power. The steering system includes hydraulic ORBITROL full-hydraulic power steering, giving operators precise control of the crane’s movements.

Safety is a top priority in the UCX300, which comes equipped with a comprehensive range of safety devices. This includes a Load Moment Limiter (LML) that prevents overloading by automatically monitoring and adjusting operations to remain within safe limits. The crane also features boom and hoist limiters, an anti-two-block system, swing lock, and a full complement of alarms for load over-hoisting and boom over-limit conditions. The operator’s cabin is designed for comfort and functionality, featuring a fully insulated and air-conditioned environment with ergonomic controls for reduced operator fatigue during extended work hours.

In summary, the Hitachi-Sumitomo UCX300 is a versatile and powerful 30-ton truck crane with advanced hydraulic systems, efficient diesel power, and comprehensive safety features. Its long boom reach, combined with mobility and ease of operation, makes it suitable for various lifting applications, including construction, industrial maintenance, and infrastructure projects.
