The next generation of KOBELCO excavators bring together superior performance and thoughtful design like never before. Performance enhancements offer greater efficiency and productivity along with increased power and speed. Design improvements provide the ultimate in comfort and control.
KOBELCO refuses to compromise, creating machines that meet every challenge.
The new SK380SR is equipped with a 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).
Model: ISUZU 6HK1
265 hp {198 kW} /1,900 rpm (SAE NET)
In addition to excellent lifting and digging performance, the SK380SR has adopted the attachment mode for a variety of tasks such as breaking and operates effectively even in narrow spaces as a single highway lane. Moreover, the cab permits operators to concentrate on work in a wide and comfortable space.
Excellent drawbar force lets you conquer rough terrain and slopes.

High hydraulic pressure (Heavy Lift) means greater lifting power, at close radius, allowing for smooth and steady operation while moving heavy objects.
Automatic Independent Travel dedicates one hydraulic pump to travel and one to the attachment on a continuous basis, allowing for a smooth and constant movement speed even while swinging or using the boom or attachment. With Independent Travel, safely carrying a large pipe across a job site is a breeze.
Our exclusive system automatically and instantly delivers full swing power during combined operations. There's no need to switch modes to make quick work of jobs like side-digging and back-filling.
Power Boost
When you need more power instantly, engage Power Boost to get 10% more power with no time limit.

Our high-resolution, large display shows right, left and rear side cameras together. Multiple display allows the operator to customize viewing needs to enhance operator awareness and jobsite safety.
The easy -to -operate menu screen and recognizable icons assist the operator to select the most important information needed to ensure jobsite safety and machine control.
Simply turn the jog dial to the right or left to select an operational feature, then press the dial to confirm selection.
A 7-way adjustable seat achieves excellent shock absorption and superior ride comfort.
Cool air is blown from multiple outlets toward the operator’s body for more comfortable operation.
Operators can move levers horizontally without twisting their wrists, reducing fatigue.
Joystick height is manually adjustable to suit operator’s preference.
Interior lights turn on and off automatically when the door is open or the ignition is turned to the OFF position. This ensures safe entry and exit in the dark.
Flip-up left console with integrated pilot control lock lever tilts for easy entry and exit from the cab.
In our pursuit of functional beauty and styling, we created an all new interior design focused with the operator in mind.
Jog Dial
This dial integrates multiple functions into a single, easy to use interface. Even with gloves on, the operator can make the adjustments they need.
LED Illumination
Dials and buttons are now backlit to provide a bright, clear view in any lighting condition.

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.

service personnel/dealer/customer
Location Data
Accurate location data can be obtained even from sites where communications are difficult.
A comparison of operating times of machines at multiple locations shows which locations are busier and more profitable. Operating hours on site can be accurately recorded, for running time calculations needed for rental machines, etc.
Fuel Consumption Data
Data on fuel consumption and idling times can be used to indicate improvements in fuel consumption.
Machine Maintenance Data
Provides maintenance status of separate machines operating at multiple sites. Maintenance data is also relayed to KOBELCO service personnel, for more efficient planning of periodic servicing.
The graph shows how working hours are divided among different operating categories, including digging, idling, traveling, and optional operations (N&B).
•This system warns an alert if an anomaly is sensed, preventing damage that could result in machine downtime.
Sends a notification if the engine is started outside of pre-defined hours.
Sends a notification if the machine leaves a pre-defined area.
