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 digging capacity. But they also had to be fuel-efficient and economical, while imposing less of a burden on the local and global environments. Applying our advanced technologies, we developed KOBELCO's 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 whole new style to the worksite while setting new standards for environmental responsibility.
Amazing Productivity with a 20 % Decrease in Fuel Consumption and “Top-Class” Cost-Performance
Significant Extension of Continuous Working Hours
The combination of a large-capacity fuel tank and excellent fuel efficiency delivers an impressive 70 % increase in continuous operation hours.
Light Lever Operation
It takes 10% less effort to move the control levers, so that operators can work longer hours with less fatigue.
NEXT-3E Technology New Hydraulic System
Rigorous inspections for pressure loss are performed on all components of the hydraulic piping, from the spool of the control valve to the connectors. This regimen, combined with the use of a new, high-efficiency pump, cuts energy loss to a minimum.
Long-Life Hydraulic Oil Reduces Replacement Costs
The long-life hydraulic oil features a base oil with excellent demulsification, with optimized wear-resistant additives and antioxidants that help to boost the service life to 5,000 hours and greatly reduce the number of changes necessary.
Highly Durable Super-fine Filter
The high-capacity hydraulic oil filter incorporates glass fiber with superior cleaning power and durability. With a replacement cycle of 1,000 hours and a construction that allows replacement of the filter element only, it’s both highly effective and highly economical.
