COMPACT YET TOUGH MINI
The Revolutionary Integrated Noise and Dust Reduction Cooling System
The highly airtight engine compartment and the offset duct contribute to noise reduction. The iNDr filter fitted in front of the cooling system ensures easy cleaning. The iNDr system on the SR Series mini excavators features air intake at the front of the machine and air exhaust underneath. It functions in the same way as the iNDr System on the SR series machines.
Visual Checking and Easy Cleaning
Because the iNDr filter removes dust from the intake air, cooling components stay dirt-free and do not require regular cleaning. The iNDr filter itself can be easily removed and cleaned without the use of tools.
iNDr Filter
The stainless-steel filter is extremely effective against dust, with 30-mesh wave-type screen that removes tiny dust particles from the intake air.
iNDr Filter Blocks Out Dust
Outside air goes directly from the intake duct through the iNDr filter for dust removal.
Solid Digging Performance
Assured Pump Flow and Pump Pressure
Pump flow of 38.4 L/min for SK30SR and SK35SR and 28.8 L/min for SK28SR, and pressure of 23.0 MPa (relief valve setting), maintain ample power.
Energy Conservation Mode
SK28SR, SK30SR and SK35SR equipped with S mode, which lowers fuel consumption by up to 25% over previous models.
One Touch Deceleration (Optional)
The machine features one-touch deceleration. It allows easy switching to an idling state, reducing the fuel consumption while the machine is at rest.
Integrated-Flow Pump System
The instant the machine begins to dig. extra output from the third pump (which otherwise powers the swing and dozer circuit) is directed to the arm circuit and boom circuit (raise) for added power. This ensures fast and smooth arm and boom raising operation even under heavy loads.
Travel Power
Large Capacity Travel Torque
The large capacity travel torque enables the machine to perform spin turn in low mode even when the dozer is pushing a heavy load.
Automatic Two-Speed Travel
An automatic shift function ensures smoother, more efficient travel on worksite. When the High mode is selected, the travel system will automatically shift to Low mode whenever the load or climbing grades requires more power.
Travel Switch
The travel lever is fitted with a button for easy switching to H-Mode travel.
Powerful and Efficient Dozer Performance
Dozer-Blade Shape
KOBELCO’ s unique blade design solves this problem by forming the earth into an arc that always falls forward. Because this prevents earth from falling behind the blade, only “one pass” is needed.
Hydraulic Pilot-Controlled Dozer
Operation Lever: The dozer lever features hydraulic pilot control for precise handling.
