Powerful, Agile, and Quiet.
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

space is at a premium.

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:

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.

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.

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. 3.
