The KOBELCO SK390LC Conventional Hydraulic Excavator is more durable than ever, able to withstand the rigors of the toughest job sites. Focusing on the global environment of the future, KOBELCO offers next-generation productivity to meet the need for lower life-cycle costs and exceed the expectations of customers the world over. It all adds up to new levels of value that are a step ahead of the times.

More power and higher efficiency.

On the job performance increase. For maximum ON THE JOB lift capacity, for pipe and handling trench boxes, KOBELCO substituted larger boom cylinders. Lift over the front is complimented via lift stability over the side. KOBELCO is utilizing it’s own design High and Wide Heavy Duty undercarriage.

Power to do more, faster

Digging Volume. The SK390LC offers dynamic digging force even as it minimizes fuel consumption, achieving class-leading work volume.

Heavy Lift

High hydraulic pressure Heavy Lift means greater lifting power, a wide radius, allowing for smooth and steady operation while moving heavy objects.

Increased power with enhanced durability to maintain the machine’s value

Smart system design increases strength and eliminates hydraulic problems. Enhanced reliability and durability takes productivity to a new level.

Built to operate in tough working environments

Reinforced and redesigned boom and arm offers excellent durability during demanding work conditions to reliably handle higher work volume.

Reduces fuel consumption and minimizes exhaust emissions

The HINO engine, a subsidiary of Toyota is renowned for fuel efficiency and environmental performance, and KOBELCO has tuned them specifically for construction machinery. The high-pressure common rail fuel injection system, the VG turbocharger, and the variable geometry (VG) turbocharger, reduce particulate matter (PM) while the large EGR cooler greatly reduces the formation of nitrogen oxide (NOx) gases.

VG turbo reduces PM

The variable geometry turbocharger adjusts air intake to maximize combustion efficiency. At low engine speeds the nozzles are closed, the air speed is increased and air intake is boosted. This helps lower fuel consumption.

EGR cooler reduces NOx

Cooled exhaust gases from the EGR cooler are mixed with fresh air in the intake. The recirculated air lowers the combustion temperature which reduces NOx.

Easy, on-the-spot maintenance

Ample space in the engine compartment allows service staff to comfortably perform maintenance in a natural body position. The distance between access steps is smaller so getting to and from the engine compartment is easier. The hood is lighter and easier to raise and lower.

Boom to Arm Regeneration System

Innovative engineering uses the downward movement of the boom to push fluid to the arm. Gravity and kinetic energy greatly reduce the amount of power needed to move fluid through the system.

Hydraulic circuit reduces energy loss

Improved hydraulic line layout minimizes hydraulic pressure resistance from turbulence and valve restrictions. Fuel efficiency is increased because it takes less energy to move fluid through a circuit with low flow resistance. Improved hydraulic piping is an effective means of reducing pressure loss.

Improved filtration system reliability

Clean, contaminant-free fuel and hydraulic fluid are essential to stable performance. The improved filtration systems reduce the risk of mechanical trouble and enhance longevity and durability.

Independent Travel

Selecting Independent Travel dedicates one hydraulic pump to travel and one to the attachment on a continuous basis. The excavator can move, turn and dig without stopping or using the optional foot pedal. When independent travel is engaged, safely moving a large piece or a job site is a breeze.

Swing Priority

The swing priority mode automatically and instantly delivers full swing power during combined operations. There’s no need to switch modes to get quick work of jobs like side-digging and back-filling.

Safety

ROPS Roll-Over Protective Structure-compliant cab complies with ISO standards and ensures greater operator safety in the event of a rollover. KOBELCO encourages operators to wear their seat belt during operation.

Cab comfort takes a step ahead

The newly refined cab puts the operator first, ensuring a quieter, more comfortable work environment and easier operation.

Comfort

Climate control outlets behind the seat. Five air outlets deliver warm or cool air directly to the operator. A light touch on the lever means smoother, less tiring work. It takes 25% less effort to work the operation lever, which reduces fatigue over long working hours or continuous operations.
