Komatsu Europe International announces the introduction of the new line of D61-23 crawler dozers powered by S3B engine technology. Based on invaluable customer feedback, and using the popular design of the D51-22 as a starting point, Komatsu refined the D61-23 to make it smarter and with up to 20% reduction in fuel consumption depending on application and working mode. With lower costs for operations and ownership; the D61-23 provides more owner- and operatorfocused features, all bundled to push productivity and efficiency to new levels.
New longer track-on-ground standard (EX) and low ground pressure (PX) models are available to offer customers flotation and weight distribution options that best match their applications. Operating weight ranges from 17,780 kg to 18,660 kg depending on the configuration. The new models push with a net of 125kW / 168 HP at 2200 rpm (ISO 9249 / SAE J1349).
Developed as a versatile multi-tool, the D61-23 is designed for a wide variety of applications, including land clearing, grading, forestry and site work. A full guarding package and other attachments are available for easy customization to meet specific customer requirements.
The latest KOMTRAX™ technology on the D61-23 sends machine operating information to a secure website utilizing wireless technology. Data such as operating hours, fuel consumption, location, cautions and maintenance alerts are relayed to the web application for analysis. The KOMTRAX™ fleet monitoring system increases machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor, and provides a wealth of other information to drive business efficiency and productivity.
Special features of these new crawler dozers include:
• EU stage IIIB / EPA Tier 4 Interim (S3B) emission certified engine
Built upon proven Komatsu Tier 3 technology, the S3B SAA6D107E-2 engine provides the same horsepower as its predecessor but lowers fuel consumption by up to 10%. Komatsu’s S3B engine platform uses an advanced electronic control system to manage airflow rate, fuel injection, combustion parameters, and after-treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability.
The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that doesn’t interfere with daily operation and keeps the operator aware of its status. This smart and simplified system removes soot using “passive regeneration” the majority of the time, to minimize “active regeneration” events.
For owners, this means lower fuel costs because of fewer active regeneration events as well as seamless operation for the operator.
As a leader in hydraulic technology, Komatsu also developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, resulting in better precision and air management as well as longer component life due to less moving parts and reduced component complexity.
• Unrivalled blade visibility and ride
The steeply sloped engine hood and new forward cab design provide more room for operators while moving them closer to the blade, for improved blade visibility, ride quality and overall comfort. The cab also has an integrated ROPS / FOPS structure and is designed with large glass windows for better visibility. Internal cab air pressure and air filters minimize dust entering the cab, and viscous cab damper mounts suppress noise and vibration when traveling over rough terrain.
• New durable and productive power angle tilt (PAT) blade
A newly designed PAT blade with a highly durable box structure and good curvature rolls material efficiently, to improve productivity. The new standard adjustable blade pitch allows the operator to adjust the aggressiveness of the cutting edge for varying applications. The new hydraulic blade angle toggle switch improves ease of blade operation. Enhanced Plug & Play provision for Topcon® is standard; only a simple bolt-on completing kit is required for the quick and easy installation of Topcon 2D/3D systems. Standard rear hydraulics for the ripper are also included for increased machine versatility.
