Two Essentials for Working in Close Quarters:
Tight Maneuverability and Quiet Operation
Offset Boom
The press-constructed boom is both lightweight and slender for
smooth operation, with hydraulic piping fitted inside the cylinders to
protect it from damage. The large offset makes it easy to dig right
next to the walls.
Performance That Ensures Top Value
The Kobelco Acera Geospec SR Series hydraulic excavators have
earned a well-deserved reputation for combining top performance
with a minimal swing radius. Advanced technologies such as the

In its offset boom configuration, the SK135SR couples its
“Ultimate”-Low Noise
Level of 93 dB(A)
tiny rear swing radius with an offset boom function that
allows it to operate with even greater efficiently in
Kobelco’s exclusive iNDr engine cooling system
delivers amazingly quite operation. In fact, the
SK135SR is 5 dB quieter than the value designated
by the Japanese government for ultra-low noise
construction machinery.
extremely limited work areas. This makes
it the ideal choice for civil engineering
projects, sidewall digging, and ditch
excavation in urban environments where
Air intake
space is at a premium.
Exhaust outlet
Strong, Straight Dozer Blade
The dent-resistant, box-type dozer blade is fitted to a
dozer arm that features superior structural strength for
highly efficient dozing operations. An optionally
available bolt-on dozer edge can be easily changed out
as needed.
Compact Working Radius
You get the best of both worlds: a roomy
cab fitted on a compact upper machine.
Rear overhang when swinging is just
245mm, with a maximum tail overhang of
only 605 mm in the forward left cab
corner. With such a small working radius,
the SK135SR is ideal for continuous
digging, swinging, and loading in tight
spaces.

Features That Go Easy on the Earth
ACERA GEOSPEC
The GEO in GEOSPEC expresses our deep
respect for our planet, and for the solid ground
where excavators are in their element. This is
accompanied by SPEC, which refers to the
performance specifications needed to get the job
done efficiently as we carry on the tradition of the
urban-friendly ACERA series.
●Min. working radius:
3,340mm
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.
Easily Meets Emission Regulations
The high-efficiency engine minimizes the emission of particulates
(PM), NOx, and smoke for environmentally friendly operation.
Automatic Acceleration/Deceleration
Function Reduces Engine Speed
Engine speed is automatically reduced when the control lever is placed
in neutral, effectively saving fuel and reducing noise and exhaust
emissions. The engine quickly returns to the previous speed when the
lever is moved out of neutral.
AIS Provided as Standard
Equipment
This function saves fuel and cuts emissions by
shutting down the engine automatically when the
machine is on stand by. It also stops the hour meter,
which helps to retain the machine’s asset value.
Meets EMC (Electromagnetic Compatibility)
Requirements
Electrical shielding ensures that the SK135SR clears all European
standards so that it neither causes nor is affected by electromagnetic
interference.

Superb Cost Performance
Easy Maintenance
Simple Select: Two Digging Modes
The new SK135SR performs much more work for the same amount
of fuel, with more dirt shifted per unit of fuel. Total fuel consumption
is reduced for greater productivity.
●Fuel
The control valves and built-in water separator are conveniently
located under the guard on the right side, which opens with a single
touch. The pump compartment at rear right opens wide for easy
access, while the iNDr filter, air cleaner, and radiator reserve tank
can be easily reached from the left side.

H-mode: For heavy duty when a higher performance level
is required.
S-mode: For normal operations with lower fuel consumption.
Attachment Mode Selector Switch
,
There s a choice of three different hydraulic circuits, to
accommodate bucket, crusher or breaker, and the desired
attachment mode can be selected with a switch, which
automatically configures the selector valve. All attachment modes
can be used in either S-mode or H-mode.

A Cooling System That Stays Clean
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.
Satisfying Swing
The powerful swing torque and high swing speed deliver faster digswing-load cycle times.

Operating Weight & Ground Pressure
Standard Configuration
Comfortable Operating Environment
Work Range Limiter
This feature prevents damage to walls,
beams and buried structures by
limiting the depth, height, and left
offset value reached by the
attachment. It both prevents unwanted
contact with external objects and
facilitates side-wall digging and other
repetitive operations.
●The operator can set operational limitations and positional
information for the bucket when
engaged in side-wall digging.
Attachment Position Indicator
Data on attachment position detected by sensors is analyzed and displayed in
the monitor.
● Depth Limit
As the bucket approaches a preset depth, operation stops automatically. Work
can be completed smoothly and safely even when close to the location of utility
pipes.
● Height Limit
As the attachment approaches a preset height, operation stops automatically.
Jobs in built-up areas with overhead electricity and telephone wires can be
completed smoothly and safely.
● Left Offset Limit
As the bucket approaches the preset offset distance, operation stops automatically. This function is very convenient for offset jobs, ensuring precise positioning of the bucket every time.

Notes:
1. Do not attempt to lift or hold any load that is greater than these lift capacities at their
specified lift point radius and heights. Weight of all accessories must be deducted from the
above lift capacities.
2. Lift capacities are based on machine standing on level, firm, and uniform ground. User
must make allowance for job conditions such as soft or uneven ground, out of level
conditions, side loads, sudden stopping of loads, hazardous conditions, experience of
personnel, etc.
