The rounded form says it all: an excavator built with a tiny rear swing for maximum maneuverability. But KOBELCO has taken this concept one step further by seeing just how much digging performance can be packed into a machine. It is not the compact design that matters so much as the performance and functions that are actually used on site.
And that’s just where the new SR Series really shines, thanks to our NEXT-3E concept. Thanks to key iNDr technology, we’ve realized a whole new level of quiet operation, backed by a next-generation power plant that pushes performance to extraordinary new heights.
Ten years after developing groundbreaking machines with tiny rear swings, KOBELCO continues to forge ahead as the leader in the field.
The iNDr Revolution
KOBELCO has developed the revolutionary integrated Noise and Dust Reduction Cooling System, with the engine compartment placed inside a single duct that connects the air intake to the exhaust outlet.
The intake and exhaust are offset, with the holes and joints in the sections corresponding to the duct wall completely covered to reduce noise at the intake and exhaust apertures. This design, plus the generous use of insulation-material inside the duct, minimizes engine noise.
The high-performance iNDr filter removes dust from intake air, ensuring a quieter, cleaner engine and keeping the cooling unit free of clogging so that no regular cleaning is necessary.
Work modes for a closer match to the job in hand. An addition to the existing H-mode and S-mode, the new ECO-mode saves even more energy
Signiffcant Extension of Continuous Working Hours
The combination of a large capacity fuel tank and excellent fuel effciency delivers an impressive max. 19 % increase in continuous operation hours.
New Hydraulic System
Rigorous inspections for pressure loss are performed on all components of the hydraulic piping, from the spool of control valve to the connectors. This regimen, combine with the use a new, high-effciency pump, cuts energy loss to a minimum.
Total Tuning Through Advanced ITCS Control
The next-generation engine control is governed by a new version of ITCS, which responds quickly to sudden changes in hydraulic load to ensure that the engine runs as effciently as possible with a minimum of wasted output.
