Aiming for Even Better Environmental Performance of Excavators
Since our founding, the KOBELCO CONSTRUCTION MACHINERY GROUP has constantly striven to develop state-of-the-art environmental technology. In addition to low fuel consumption performance that is among the best in the world, low noise generation, and the development of environmentally friendly engines that provide clean exhaust gas, our machines are equipped with our own unique advanced system that utilizes IoT to improve work efficiency and safety. KOBELCO CONSTRUCTION MACHINERY's hydraulic excavators are still continuing to evolve.
Pursuing the Challenge of Low Fuel Consumption to Revolutionize the Industry
We have achieved improved fuel consumption performance in all modes in comparison with previous models by introducing a new boom/arm energy regeneration that efficiently controls the hydraulic flow and by reducing pressure loss. We have achieved an approximate 38% reduction in fuel consumption over the past 10 years.
Satisfies 2014 Exhaust Gas Regulations: Providing Clean Exhaust Gas
The engine exhaust system is equipped with an urea SCR*1 system that breaks down NOx*2 into harmless nitrogen and water. The combination of this system with exhaust gas after-treatment devices*4 that thoroughly collect and incinerate PM*3 provides extremely clean exhaust gas.
*1. SCR: Selective Catalytic Reduction
*2. NOx: Nitrogen oxides
*3. PM: Particulate matter
*4. Exhaust gas after-treatment devices: DPF or DOC
New Functions to Optimize Excavator Performance
ICT Implemented Services Greatly Improve Work Site Productivity
"Horunavi"
Horunavi is an ICT implemented brand combining the Japanese word "horu" (dig) with "navi" for navigation. There are 2D guidance systems that can be introduced as easily as car navigation system, and 3D guidance systems that use GNSS* to measure the three-dimensional position and orientation of construction machinery enabling you to work with greater precision while comparing with design data. We have also added the "Horunavi + Plus", 3D machine control that allows you to perform construction work according to design drawings using only arm lever control or carry out work while preventing excessive digging against design drawings. These options provide support for improved productivity with ICT implementation according to the work site application.
* GNSS: Abbreviation for Global Navigation Satellite System, a positioning system using satellites such as GPS.
Collision Reduction System: First Construction Machinery Manufacturer with This New Technology
"K-EYE PRO"
The "K-EYE PRO" function notifies the driver by a displayed message and alarm if a person or object is detected in the machine's blind spot when swinging or traveling in reverse, after which the machine's speed is automatically reduced or the machine is stopped. It is effective in reducing accidents involving the crushing of body parts or being run over, which account for 60% of construction site accidents.

Control When Traveling in Reverse
KOBELCO CONSTRUCTION MACHINERY's Unique Preventive Maintenance System
"KSCAN"
This system reads in data such as water and oil temperatures, fuel injection amounts, and pump output to monitor conditions by remote control using IoT. When service personnel perform maintenance, they perform a physical examination at high idling speed, and the data is promptly processed by the KOBELCO server in order to detect unnoticeable possible problems by performing a detailed analysis using the human eye and data analysis. This system functions to prevent errors so that excavators can operate stably.
Evolution of Crane Environmental Performance
We have continuously pursued environmental performance in our cranes as well, as shown by the evolution of the Mastertech-G Series, the first in the industry equipped with numerous energy-saving functions, and the G-Mode, KOBELCO CONSTRUCTION MACHINERY's in-house developed energy saving system. The latest "TK750G" crane provides improved transportability due to its transport width (less than 3m), as well as being equipped with an engine that satisfies the 2014 exhaust gas regulations, so that this new model combines workability and durability with excellent environmental performance.
Minimum Transport Width of 2.99 Meters. Compact Layout Provides Excellent Transportability
The "TK750G" is a new model of the TK series, which continues to receive high praise from customers, that is mostly used for civil engineering and foundation work. Current features of the series, such as a robust structure and high lifting capability, have been retained, and the new model features a transport width of 2.99 meters to simplify trailer arrangements and application procedures. We further improved transportability with a new optional boom attachment/detachment device and self-attachment/detachment crawler device.
Equipped with an Engine Satisfying the Most Recent 2014 Exhaust Gas Regulations
The engine is equipped with an "urea SCR" that serves as an exhaust gas after-treatment device. In comparison with previous models, this engine reduces PM*1 by approximately 80% and NOx*2 by approximately 93% to provide clean exhaust gas and comply with strict emission regulations. Additionally, the use of low-noise engineering enables it to comply with standard values for low-noise construction machinery, and the new engine demonstrates excellent environmental performance with special attention paid to exhaust gas and noise.
*1. PM: Particulate matter
*2. NOx: Nitrogen oxides
Excellent Durable Structure to Withstand Hard Civil Engineering and Foundation Work
The adoption of a boom with a highly rigid four-plate design incorporating optimized materials, structure, and welding provides lightweight and durable crane. Equipped with reinforced shoes for which the shape, thickness, and material have been changed, this model has also increased Its overall strength.
