Sumitomo SC350

Sumitomo’s SC350 crawler crane presents a combination of strength and agility in the 35-ton lifting class. It is designed with the following specifications:

Normal Crane

• Maximum Lifting Capacity: The crane has a maximum lifting capacity of 35 tons at a 3.6-meter radius, catering to a variety of heavy-lifting tasks.
• Boom and Jib: The main boom extends up to 43 meters, ensuring significant vertical reach, and is complemented by a jib that extends from 6.1 to 15.25 meters, providing flexibility in reach and angle.
• Tower Crane Boom Length: An optional tower crane boom extends between 3 to 6 meters for specialized lifting operations.
• Maximum Load Moment: A strong load moment of 40.00m with the base section weighing 5.8t illustrates the crane’s powerful lifting capabilities.
• Travel Speed: A maximum travel speed of 2.0/0.4 km/h allows for easy relocation around the job site.
• Engine and Performance: Powered by a robust engine, likely a Mitsubishi model, it ensures reliable operation and ample power for crane movements.
• Gradeability: The crane can tackle steep inclines with a gradeability of 40%, suitable for various terrain conditions.
• Ground Pressure: With a weight of 41.1 tons, it maintains a low ground pressure of 0.60 kg/cm², minimizing impact on the ground even in less stable soil conditions.

Clamshell Configuration

With the clamshell bucket attachment, the SC350’s versatility in excavation and material handling is greatly enhanced. This configuration allows for efficient deep digging operations, whether for construction, dredging, or other specialized projects.

• Bucket Capacity: The crane can operate with either a 0.8m³ or 1.0m³ clamshell bucket, providing flexibility based on the volume of material to be handled.
• Lifting Capacities: With the 0.8m³ bucket, it can lift up to 42.2 tons, and with the 1.0m³ bucket, it can handle up to 42.6 tons.
• Boom Length: The crane’s boom can be extended from 10.00 meters to a considerable depth of 19.00 meters, catering to various project depths.
• Hoisting Speeds: The clamshell operation is efficient with hoisting speeds of 80/40/15/7.5 meters per minute.
• Closing and Opening Times: It has a quick closing time of 64 seconds and an opening time of 12 seconds, streamlining the digging cycle.
• Slewing Speed: The crane maintains a slewing speed of 3.4rpm, allowing for smooth operation and quick positioning.
• Travel Speed: The crane’s undercarriage is capable of traveling at 2.0/0.4 km/h, facilitating repositioning on job sites.
• Ground Pressure: With the clamshell attachment, the ground pressure is a low 0.6 kg/cm² with the 0.8m³ bucket and 0.62 kg/cm² with the 1.0m³ bucket, minimizing the impact on the job site terrain.
