The SK Series Concept of Beautiful Performance. The Power Wave of Change When we set out to design our new hydraulic excavators, we kept our eyes on the big picture. Of course we wanted machines with greater diggin capacity. But they also had to be fuel-efficient andeconomical, while imposing less of a burden on the local and global environments. Applying our advanced technologies, we developed SK series, an entirely new kind of excavator that beautifully balances all the demands of today’s construction industry. Lean and efficient with capacity to spare, these sleek powerhouses bring a...

Efficient Performance! NEXT-3E Technology Next-Generation Electronic Engine Control The high-pressure, common-rail fuel-injection engine features adjustable control to maximize fuel efficiency and provide powerful medium/low-speed torque. The result is a highly fuel-efficient engine. Amazing Productivity with a 27 % Increase in Work Volume and “Top-Class” Cost-Performance Work Volume * For heavy duty when a higher H-Mode performance level is required. increase in work volume using the same amount of fuel. (H-Mode) Fuel Consumption* decrease in fuel consumption even when performing more work...

Reliability, Durability, Environmental Responsibility The Value and Quality of Sturdy Construction! Designed for the Environment and the Future! Emergency Acceleration (Dial) Permits Continued Operation in the Unlikely Event of Malfunction Stable Attachment Strength If unexpected trouble is experienced with the ITCS mechatronic control system, the machine can still be operated using the emergency acceleration system. Digging modes are also automatically relayed to an emergency system so that digging can continue temporarily until a service person arrives to repair the primary system. Forged...
