Kobelco 7250-2F Load Chart PDF + Specifications

The Kobelco 7250-2F is a versatile 250-ton hydraulic crawler crane engineered for demanding lifting applications across industrial and infrastructure projects. At its core is a powerful Hino P11C-UN turbocharged diesel engine producing 247 kW, compliant with European Stage IIIA and US EPA Tier III emissions standards. This power drives a sophisticated hydraulic system featuring four variable displacement pumps, which deliver smooth and responsive operation across all functions, including main and auxiliary hook hoists, boom hoist, and swing systems.

Its standard crane boom can extend up to 76.2 meters, providing a lifting capacity of 250 tons at 4.6 meters radius. For extended reach projects, the 7250-2F can be configured with a long boom of up to 91.4 meters. The crane also offers fixed jib combinations of up to 76.2 meters of boom plus 30.5 meters of jib, and tower jib setups of up to 64.1 meters of tower with 51.8 meters of jib, allowing the crane to adapt to complex lift scenarios with ease. The tower jib can operate at angles between 60° and 90°, providing additional flexibility in tight site conditions.

The crane’s hoisting systems are robust, with main and auxiliary winches featuring maximum line speeds of 110 m/min and rated single-line pulls of 132 kN. The swing system provides 360-degree continuous rotation at 2.2 rpm, powered by planetary reducers and controlled with a spring-set, hydraulically released multiple-disc brake system for secure, precise operation.

Designed for ease of transport and assembly, the 7250-2F has a modular build with quick-disconnect crawler assemblies and removable counterweights totaling 97.1 tons. It boasts strong mobility, with a travel speed up to 1.1 km/h and gradeability of 30%, supported by 1,070 mm wide crawler shoes (or optional 1,220 mm shoes).

Operator comfort is ensured by a fully enclosed, air-conditioned cab equipped with ergonomic controls, comprehensive monitoring systems, and safety features such as boom backstops, swing locks, and outriggers designed for maximum stability on site.

In summary, the Kobelco 7250-2F combines high lifting capacity, extended reach options, advanced hydraulic control, and reliable structural engineering, making it an excellent choice for heavy lifting applications in construction, energy, and infrastructure sectors.
