Detailed Introduction of KOBELCO SK75 Excavator

The KOBELCO SK75 is a 7-ton class mid-sized compact excavator developed by Kobe Steel Group (KOBELCO), a world-leading Japanese construction machinery manufacturer famous for its industry-leading energy-saving technologies, high structural durability and reliable after-sales support. Positioned for light to medium-duty construction scenarios, the SK75 series balances strong power output, ultra-low fuel consumption and flexible maneuverability, making it one of the most popular models in its class across global markets.

1. Power & Emission System

The SK75 is equipped with a Yanmar 4TNV98C four-cylinder water-cooled diesel engine, which delivers a rated net power of 43 kW at 2000 rpm. It complies with the latest global emission standards including EPA Tier 4 Final, EU Stage V and China National IV, with low exhaust emissions suitable for urban construction projects with strict environmental requirements.Integrated with KOBELCO’s exclusive Intelligent Total Control System (ITCS), the powertrain optimizes the matching between engine output and hydraulic demand in real time, reducing unnecessary energy loss by over 12% compared with similar models in the market. Its average operating fuel consumption is only 3-5L per hour, greatly cutting down daily operation costs for users.

2. High-efficiency Hydraulic System

The SK75 adopts an imported Kawasaki negative-flow hydraulic system, which features precise flow distribution and fast response speed. Its independent flow control technology for boom, arm and bucket ensures smooth and coordinated compound actions (such as simultaneous boom lifting and arm retraction), with excellent micro-operation accuracy for fine construction works like slope trimming and pipeline trenching.The model has a maximum bucket digging force of 56 kN and arm digging force of 38 kN, with a travel traction force of over 60 kN, supporting stable operation on uneven construction sites and a 30° (58%) gradeability. It is pre-installed with auxiliary hydraulic pipelines as an optional configuration, which can directly match with attachments like hydraulic breakers, wood grapples and augers without secondary modification.

3. Durable Structural Design

All key structural parts including the boom, arm and X-type undercarriage are made of high-strength wear-resistant steel, subjected to 100,000 hours of fatigue test verification, which can adapt to long-term high-load operation conditions. The undercarriage is available in steel track or rubber track options, with sealed and lubricated track rollers, idlers and sprockets to extend service life and reduce daily maintenance frequency.Its minimal tail swing radius is only 1,750 mm, which greatly reduces the risk of collision with surrounding obstacles in narrow work zones such as urban alleys, indoor demolition sites and basement construction sites. The standard bucket capacity ranges from 0.3 m³ to 0.4 m³, and reinforced heavy-duty buckets are available for harsh working conditions like rock excavation.

4. Operator Comfort & Safety

The SK75’s cab is certified with ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure), which fully guarantees the personal safety of operators in case of accidents. The cab is equipped with a multi-adjustable air suspension seat, low-resistance pilot control joysticks and a fully-sealed sound insulation design, with internal noise controlled below 72 dB(A), greatly reducing operator fatigue during long-hour operation.Other comfort configurations include a high-definition LCD instrument panel that displays real-time operating data (fuel consumption, water temperature, fault codes, etc.), a high-performance air conditioning system with fast cooling and heating functions, and wide panoramic glass with almost no blind area. Optional configurations such as rear view camera and LED working lights are also available to improve operation safety at night or in low-visibility environments.

5. Easy Maintenance & Intelligent Management

All daily maintenance points including fuel filters, oil filters, air filters and hydraulic oil ports are arranged at ground-accessible positions, eliminating the need to climb the machine for regular maintenance, greatly saving maintenance time. The dual-stage air filter has high dust filtration efficiency, which is very suitable for construction sites with large dust content. The hydraulic oil replacement cycle is up to 5,000 operating hours, and the engine oil maintenance cycle is 500 hours, reducing long-term maintenance costs.The SK75 is also equipped with KOBELCO’s exclusive KOMEXS remote monitoring system as standard, which supports real-time checking of equipment location, operating hours, fuel consumption and fault warning, facilitating fleet management for individual users and engineering contractors.

6. Main Application Scenarios

The KOBELCO SK75 is widely used in:

Municipal engineering: pipeline trenching, road repair, landscaping, tree planting
Rural infrastructure: homestead renovation, farmland water conservancy construction, village road paving
Narrow space operations: indoor demolition, basement construction, alley renovation
Special operations: concrete structure crushing, wood handling, pile drilling (with corresponding attachments)
