With the release of the SK380SRLC, KOBELCO has completely

harmonised the values of PERFORMANCE and DESIGN.

The SK380SRLC delivers greater efficiency and productivity

with increased power and speed, along with uncompromising

operator comfort and machine operability.

In the pursuit of producing unique and unbeatable machines

that provide comfort and productivity without equal, KOBELCO

continues to rise to the challenge.

 THE ULTIMATE SLEEK AND STYLISH CAB DESIGN
True ergonomic functionality combined with modern design has resulted in a cabin interior that is
sleek and comfortable, built for simplicity and operator comfort.

Jog dial
The jog dial integrates multiple functions to allow for simple
navigation of machine information screens, even while wearing gloves.

LED backlights
LED backlighting on switches and dials provides a bright, clear view of
controls, even in the dark, while delivering a premium look and feel.

UNFORGETTABLE COMFORT

Air suspension seat

A GRAMMER* seat is installed as standard equipment,
which achieves excellent shock absorption and
superior ride comfort.
*GRAMMER is trademark of GRAMMER AG. registered in Germany
and other countries.

Optimal air conditioning vent placement

Air conditioning vents are optimally placed around the
cabin with air flow directed toward the operator’s neck
and back, providing more comfortable operation.

Ergonomic and low-effort pilot

control levers
Pilot control levers are mounted on adjustable consoles,
with an ergonomic design that allows movement
without twisting, reducing operator fatigue.

New Hydraulic Control

Our newly upgraded hydraulic control system responds to
shorter lever strokes than current models, delivering
swifter, more precise movement and improved lever
operability.

LED door light

The LED interior light automatically turns on when the
door is opened or when the ignition is set to OFF.
This ensures easy entry and exit at nighttime.

IDEAL FOR URBAN WORK

SITES WITH A WIDE
WORKING RANGE

Minimal swing radius improves efficiency

The tail of the upper body extends very little past the
crawlers, so the operator can concentrate on the job at hand.
This also reduces the risk of collision damage.

Easy workability even in Close Quarters

The compact design allows continuous 180° dig, and load
operations within a working space of just 5.35m.

Figures above show the value for

standard boom and standard arm spec.

THE NEXT LEVEL OF PERFORMANCE

Improved Efficiency, plus a Tier IV Final Compliant Engine
The new SK380SRLC is equipped with an Isuzu Tier IV Final compliant engine, which has a
higher torque value.
This engine is fitted with a diesel oxidation catalyst (DOC) and an SCR device to control
emissions without using a diesel particulate filter (DPF).

Heavy Lift
This switch is used when lifting a heavy load and increased power is required.
Heavy Lift provides 10% more hydraulic pressure and provides greater lifting
power at close radius. This allows for a smooth and steady operation while
moving heavy objects.

The flow-rate modes of the bucket, breaker, nibbler, and rotating
grapple are set before delivery, which allows you to start
operating immediately.
Mode settings for other attachments, such as the tilt rotator, can
easily be added or changed.

Note:
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. Bucket pin attachment point defined as lift point.
4. The above lift capacities are in compliance with ISO 10567. They do not exceed 87% of hydraulic lift capacity or 75% of tipping load. Lift capacities marked with an asterisk(*) are limited by
hydraulic capacity rather than tipping load.
5. Operator should be fully acquainted with the Operator’s and Maintenance Instructions before operating this machine. Rules for safe operation of equipment should be adhered to at all times.
6. Lift capacities apply to only machine as originally manufactured and normally equipped by KOBELCO CONSTRUCTION MACHINERY CO., LTD.
