Sumitomo SC500-2

The Sumitomo SC500-2 is a versatile 50-ton class lattice boom crawler crane designed for heavy-duty construction, infrastructure, and general-purpose lifting. It features a robust design and flexible boom configurations, making it suitable for both confined and open work sites. The standard boom configuration ranges from 12.2 m to 42.65 m, while the short boom ranges from 9.8 m to 40.3 m, both offering a maximum tip height of around 45.25 m when combined with a 15.25 m insert.

The crane is powered by a Hino H07CT diesel engine, delivering 132.4 kW (180 PS) at 2,100 rpm, ensuring sufficient power for hoisting and travel operations. Its maximum line speed is 62 meters per minute for both main and auxiliary winches, with a main winch lowering speed of 110 m/min, ensuring efficient load handling.

In terms of working range, the SC500-2 supports a lifting radius from 6.10 m to 15.25 m depending on boom configuration, with a rated lifting capacity of 50 tons at 4.0 m radius. The hoist rope reeving ranges from 1 to 8 parts, corresponding to lifting capacities from 6.3 t up to the maximum of 50 t, depending on the number of falls used.

Mobility is supported by a crawler undercarriage with a maximum travel speed of 1.6 km/h, and it handles slopes with a maximum gradeability of 40% (22°). The machine’s ground pressure is well distributed with wide crawlers (760 mm), resulting in low bearing pressure: 68.0 kPa (0.69 kg/cm²) on the standard boom model and 67.5 kPa (0.69 kg/cm²) on the short boom version.

The total machine weight is approximately 52.9 tons (standard boom) or 52.5 tons (short boom), inclusive of the base machine and standard counterweights. The crane can be outfitted with various hooks including a 50-ton 4-sheave hook (750 kg), a 35-ton 3-sheave hook (500 kg), a 15-ton 1-sheave hook (350 kg), and a 5.8-ton auxiliary hook (120 kg).

Designed with simplicity and reliability in mind, the SC500-2 is a proven workhorse for contractors needing a dependable crawler crane in the 50-ton class range. Its compact dimensions, straightforward operation, and solid lifting capability make it a practical solution across multiple job types.
