2. Powertrain System

The SK140 is equipped with a Hino J05E-TF 4-stroke water-cooled turbocharged diesel engine, which meets the latest Euro Stage V, US EPA Tier 4 Final and China National IV emission standards:

Adopts optimized high-pressure common rail fuel injection technology, with high low-end torque output, strong adaptability for heavy load working conditions at low speed
Equipped with KOBELCO’s exclusive intelligent ECO mode, which reduces fuel consumption by 10%-15% compared with other 14-ton class excavators on the premise of ensuring operation efficiency
Built-in automatic idle and automatic shutdown functions, which reduce unnecessary fuel consumption and noise when the machine is idle for a long time
Excellent cold start performance, supports normal start-up at ambient temperature as low as -15℃ without additional preheating devices

3. Hydraulic System

KOBELCO’s proprietary intelligent electro-hydraulic proportional control system is the core advantage of the SK140:

Adopts imported Kawasaki hydraulic pumps and valves, with precise flow matching between power and hydraulic output, reduces unnecessary hydraulic loss by more than 8%
Smooth composite action performance, no lag or卡顿 when operating boom lifting, swing and arm movement at the same time, high operation precision, suitable for fine work such as trench excavation and site leveling
Equipped with a 3-stage high-precision hydraulic oil filtration system, extends the hydraulic oil replacement cycle to 5,000 hours under normal working conditions, greatly reduces maintenance costs
Built-in overpressure protection function, effectively avoids damage to hydraulic components under impact load

4. Operation Performance

Three adjustable operation modes to meet different working demands:
- P (Power) mode: Full power output, suitable for heavy load conditions such as hard soil excavation and concrete breaking
- E (Economy) mode: Balances efficiency and fuel consumption, for daily earthwork transfer and site leveling
- A (Auto) mode: Automatically adjusts power output according to real-time load, realizes optimal energy efficiency
Strong walking traction, the long crawler (LC) version has low ground pressure, can run stably on soft soil, muddy and mountainous roads
Supports optional accessories including hydraulic breaker, log grapple, ripper, quick coupler, to adapt to diversified operation scenarios

5. Structure & Durability

The main frame, boom, arm and undercarriage are all made of high-strength wear-resistant steel plate, and the stress concentration parts are reinforced by thickening and welding, which can withstand long-term impact load under harsh working conditions
The track chain, support rollers and idlers adopt fully sealed design, effectively prevent sediment from entering, extend the service life of walking parts by more than 20%
The standard bucket is made of high-hardness wear-resistant alloy steel, and the cutting edge adopts replaceable high-wear-resistance parts, which reduces wear loss during long-term excavation of gravel and hard soil
The whole machine adopts cathode electrophoresis + powder coating process, has strong rust and corrosion resistance, and is suitable for high-salt fog coastal working conditions

6. Cabin Comfort & Safety

The cabin meets international ROPS (Roll Over Protective Structure) and FOPS (Falling Object Protective Structure) certification, which effectively guarantees the safety of operators
Equipped with multi-directional adjustable shock-absorbing seat, low-force pilot control joystick, reduces operator fatigue during long-term operation
Full-automatic high-power air conditioning system, with reasonable air outlet layout, realizes rapid cooling and heating in extreme temperature environments
The interior noise of the cabin is controlled below 75dB(A), equipped with radio, USB charging port and large storage space, greatly improving the operating experience
Large-area panoramic glass design, small blind area, provides the operator with a wide view of the working area and surrounding environment

7. Maintenance Convenience

All daily maintenance points (oil filter, fuel filter, air filter, oil filling port) are arranged at the ground-accessible position, no need to climb the machine to complete routine maintenance, saving maintenance time
The two-stage air filter has high filtration efficiency, suitable for high-dust working conditions such as mines and demolition sites
Equipped with a fuel pre-filter with water separation function and water level alarm, which effectively prevents water from entering the engine and reduces engine failure rate
Supports remote fault diagnosis function, KOBELCO after-sales team can monitor the operating status of the machine in real time, and give early warning of potential faults, reducing downtime

8. Typical Application Scenarios

Municipal engineering: Road construction, pipe network excavation, greening transplantation, small-scale urban demolition
Landscaping: Site sorting, tree pit excavation, slope trimming
Small and medium-sized earthwork projects: Foundation pit excavation, site leveling, earthwork transfer
Agricultural and water conservancy projects: Farmland renovation, ditch excavation, small water conservancy construction
Auxiliary mining operation: Material loading, road clearing, concrete breaking with hydraulic breaker

Non flooded

No accident
