Sumitomo SC650DD-2 Load Chart PDF + Specifications

The Sumitomo SC650DD-2 is a high-performance 65-ton crawler crane built for versatile lifting applications across construction and infrastructure projects. With a maximum lifting capacity of 65 metric tons at 4.0 meters, this model delivers reliable performance for mid-range lifting tasks. The crane’s main boom starts from a basic length of 9.65 meters and extends up to a maximum length of 43.20 meters, offering considerable reach flexibility for field operations.

At the heart of the SC650DD-2 is a Mitsubishi 6D22T turbocharged diesel engine, producing 169.2 kW (230 PS) at 2,000 rpm. The engine ensures optimal balance between fuel efficiency and power output, suitable for continuous duty cycles. The crane features a travel speed of 1.2 to 1.8 km/h and a gradeability of 40%, giving it ample mobility over uneven or sloped terrains. It operates with a ground pressure of 0.77 kgf/cm² when equipped with 810 mm shoes.

Operational functions include smooth control of the hoist speeds at 70–4 m/min, including front and rear winches, while optional third drum hoisting allows up to 65–4 m/min. The slewing speed ranges from 1.0 to 3.0 rpm, offering flexibility for various lifting alignments.

Weighing approximately 68.6 tonnes, the SC650DD-2 is engineered with safety and operator ergonomics in mind. Standard equipment includes load indicators, anti-two block safety devices, hydraulic monitoring alarms, and air-conditioned cabins for enhanced comfort. The crane is also fitted with a complete instrumentation system, visibility aids (such as mirrors and sun visors), and an SC controller for efficient crane operation.

The SC650DD-2 supports optional accessories like walkways, third drums with free-fall functions, drum cameras, counterweight self-assembly systems, and auxiliary jibs. Its versatile boom and jib attachments—such as 3.05 m or 6.10 m extension booms—enable configuration for diverse jobsite conditions.

In summary, the Sumitomo SC650DD-2 stands as a dependable 65-ton class crawler crane, combining efficient Japanese engineering with practical field adaptability. Its robust build, high-lift performance, and operator-focused systems make it a capable solution for medium-scale lifting tasks across various industries.
