2. Core Advantages & Features

2.1 High Efficiency & Ultra-low Fuel Consumption

Equipped with Kobelco’s proprietary ES (Electronic System) hydraulic control system, it realizes precise matching of engine output and hydraulic load, with smooth composite actions (simultaneous boom lifting, swing, arm retraction, etc.) and 10% higher operation cycle efficiency than competitors in the same class.
The exclusive iNDr (Intelligent Noise and Dust Reduction) cooling system optimizes heat dissipation efficiency, reduces engine load, and cuts comprehensive fuel consumption by 12-15% in ECO mode, with an hourly fuel consumption of only 3-5L under light load conditions.

2.2 Flexible Operability & Strong Versatility

The short-tail swing design and compact body allow it to operate freely in narrow spaces such as urban alleys, residential communities, and indoor construction sites, without colliding with surrounding obstacles.
It supports quick replacement of multiple attachments, including hydraulic breakers, wood grapples, augers, dredging buckets, and rippers, to meet the needs of different operation scenarios. The standard front dozer blade can be used for site leveling and backfilling, improving one-machine multi-purpose capability.

2.3 High Reliability & Low Maintenance Cost

The boom, arm, and chassis frame are made of high-tensile steel, with reinforced welded joints, which can adapt to long-term heavy-load operation. The core components including the engine and hydraulic pump have passed more than 10,000 hours of extreme condition verification, with low failure rate.
All daily maintenance points are arranged at ground-accessible positions, which is convenient for inspection and replacement of filters and oil. The hydraulic oil replacement cycle is up to 4,000 hours, and the engine oil replacement cycle is 500 hours, which effectively reduces downtime and operation cost.

2.4 Comfortable Operating Experience

The cab is ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) certified, with fully sealed design, the internal operating noise is as low as 72dB, and the dust isolation effect is excellent.
It is equipped with a fully adjustable suspension seat, low-force operating joysticks, high-efficiency automatic air conditioning, and a high-definition LCD monitor that displays real-time data such as fuel consumption, working hours, and fault codes, greatly reducing the fatigue of long-term operation. The wide field of view also effectively reduces the blind area of operation and improves safety.

3. Typical Application Scenarios

Urban municipal construction: pipeline trenching, sidewalk renovation, small earthwork, etc.
Landscaping: tree pit digging, site leveling, nursery transplanting, etc.
Agricultural infrastructure: irrigation canal construction, farmland consolidation, greenhouse foundation excavation, etc.
Small demolition: small building demolition, concrete breaking, waste recycling, etc.
Material handling: sand and gravel loading, timber handling, bulk cargo transfer, etc.

4. Optional Configurations

Customers can choose customized configurations according to actual needs:

Rock bucket, narrow trenching bucket, and other special buckets
Quick coupler for attachment replacement
Auxiliary hydraulic pipeline for breakers and other attachments
Rubber crawler (to avoid damaging urban pavement)
Extended dozer blade
Rearview camera, heated seat, etc.

As a star product of Kobelco’s small excavator lineup, the SK75 balances operation efficiency, use cost and durability, and is an ideal choice for small and medium-sized engineering operators.
