Hitachi-Sumitomo 800HLX

The Hitachi-Sumitomo 800HLX is an 80-ton hydraulic crawler crane engineered for medium to heavy-duty lifting operations. Powered by a Cummins QSB 6.7 diesel engine, the crane delivers 201 kW (273 PS) at 2,000 rpm, complying with Tier 4 Final emissions standards. The engine’s 6.7-liter displacement ensures high efficiency and strong performance for both lifting and travel functions.

Boom & Configurations:

The crane offers flexible boom configurations, with a standard boom length ranging from 9.5 to 54.5 meters. In its auxiliary sheave-equipped configuration, the boom can extend from 9.5 to 48.5 meters, providing adaptability for different project needs. The boom hoist winch uses a 16 mm rope, allowing for a smooth lifting experience, while its maximum boom hoisting speed is 150 m/min.

Winches:

The 800HLX is equipped with powerful front and rear winches, both utilizing 26 mm ropes with a maximum speed of 210 m/min. Each winch has a rated line pull of 108 kN (11 tons), ensuring strong and consistent lifting capabilities. For auxiliary operations, a third optional winch with a 22.4 mm rope diameter and 180-meter length is available, offering a line pull of 69 kN, making it suitable for additional lifting tasks.

Performance:

The crane has a maximum rope speed of 105 m/min for the front/rear winches under full load conditions (11 tons), and 90 m/min for the optional third winch under similar conditions. Its slewing speed of 5.0 rpm ensures efficient and precise load positioning, making it ideal for repetitive and heavy lifting tasks. The crane also features a gradeability of 30% (17 degrees), allowing it to operate effectively on sloped or uneven terrain.

Counterweight System:

For stability during heavy lifts, the crane employs a modular counterweight system with a total weight of 28.2 tons, distributed across various segments for flexible configuration. This counterweight setup ensures that the crane remains balanced and secure, even at its maximum lifting capacity.

Mobility & Hydraulic System:

The crane is supported by a robust crawler system with 800 mm wide flat shoes, providing excellent stability and low ground pressure. The travel speed ranges from 1.8 km/h in high mode to 1.2 km/h in low mode, with smooth movement facilitated by a well-designed undercarriage. The hydraulic system operates at a maximum pressure of 31.4 MPa, and the pump system delivers high flow rates (280 L/min from P1 and P2), ensuring efficient operation across all crane functions.

Operator & Control:

The operator cabin features advanced control systems, including a pilot hydraulic control system that ensures smooth operation. An 8.4-inch display provides real-time feedback on crane functions, improving operational safety and precision. The control levers are designed for ease of use, enhancing operator comfort during long working hours.

Applications:

The Hitachi-Sumitomo 800HLX is ideal for a wide range of construction applications, including infrastructure projects, industrial installations, and general construction lifting. Its combination of high lifting capacity, flexibility in boom configurations, and advanced control systems make it a versatile and reliable crane for medium to heavy lifting operations.

In summary, the 800HLX is a powerful, efficient, and adaptable 80-ton crawler crane that excels in various lifting scenarios, offering strong winch performance, flexible boom configurations, and reliable hydraulic systems for a wide range of construction projects.
