KOBELCO SK485 MARK 9 CRAWLER EXCAVATORS

Technical Description

The Kobelco SK485 Mark 9 is a heavy-duty excavator designed for high performance with a robust Tier 4 Interim Hino engine delivering 345 horsepower (257 kW). It features an operating weight of 111,774 pounds, making it the largest model in its series, and provides a maximum digging depth of 25.6 feet (25 ft 7.5 in). This model incorporates the Intelligent Total Control System (ITCS), an advanced hydraulic control technology that enhances operational smoothness and efficiency through integrated swing priority and automatic hydraulic regeneration. The latter improves response times and reduces energy consumption by prioritizing oil flow within cylinders. The excavator offers three working modes—H Mode for heavy-duty excavation, S Mode for standard digging, and E Mode for economy—to optimize power usage and fuel efficiency, achieving up to 15 percent better fuel economy compared to previous models thanks to cooled exhaust gas recirculation (CEGR) emission technology. Two attachment modes support breaker and auxiliary tool applications, allowing flexibility in demolition and construction tasks. Operator comfort and safety are enhanced with a newly designed ROPS/FOPS cab providing a spacious environment, improved visibility through a rear-view camera, and a low engine cover. Additional features include swing flashers, step extensions, and standard plug-in telematics compatibility for real-time machine monitoring. The SK485 Mark 9 is built for challenging projects such as road and bridge construction, sewer installation, and large-scale underground utilities, combining power, precision, and efficiency in a durable platform.
