Sumitomo SC2500

The Sumitomo SC2500 is a heavy-duty crawler crane with a maximum lifting capacity of 250 metric tons. It is designed for large-scale lifting operations in infrastructure, plant construction, and heavy industry. The crane operates on crawler tracks, which provide excellent stability and mobility on rough or soft ground.

The crane uses a lattice boom system. The standard boom can be extended from 12.2 m to 91.0 m, while a tower boom configuration offers lengths from 18.3 m to 73.2 m. The luffing jib has a working range of 18.3 m to 59.5 m, and when combined with the tower boom, the total system can reach a maximum length of up to 94.5 m. There is also a fixed jib option of 67.1 m + 10 m, and a heavy-duty hammerhead boom of 250t x 4.5 m is available for specific lifting applications.

The crane is powered by a Mitsubishi 6D22-T diesel engine, delivering 220.6 kW (300 PS) at 2,000 rpm. This high-output engine supports simultaneous crane motions and ensures reliable performance under continuous operation. Travel speed is approximately 0.9 / 0.6 km/h, depending on terrain, and the swing speed is 1.5 / 0.8 min⁻¹ (rpm).

The hoisting speeds are variable depending on the line and configuration:

• Main winch (1st layer): 90 / 69 / 45 / 35 m/min
• Auxiliary winch: 90 / 69 / 45 / 35 m/min
• Luffing jib hoist: 45 m/min
• Tower boom winch: 45 m/min
• Boom hoist: 40 m/min

The crane features modular counterweights for balancing during lifts, and the base machine weight is approximately 191 t, depending on configuration. The ground pressure in working condition is around 1.18 MPa, ensuring good load distribution on site.

Ergonomically, the SC2500 is equipped with a modern operator cab featuring advanced control levers, safety monitoring systems, and electronic load indicators. The cab includes climate control, improved visibility, and a user-friendly interface for long working hours.

In summary, the Sumitomo SC2500 is a robust and reliable 250-ton crawler crane offering a wide range of boom and jib configurations, powerful lifting performance, and smooth control, making it a solid choice for demanding lifting operations.
