KOMATSU PC490LC-11 Grandes excavatrices
Caractéristiques du produit
Nouveau moteur Tier 4 Final
The Komatsu SAA6D125E-7 engine is EPA Tier 4 Final emissions certified and provides exceptional performance while reducing fuel consumption. Based on Komatsu proprietary technologies developed over many years, this new diesel engine reduces nitrogen oxides (NOx) by more than 80% when compared to Tier 4 interim levels. Through the in-house development and production of engines, electronics, and hydraulic components, Komatsu has achieved great advancements in technology, providing high levels of performance and efficiency in virtually all applications.
Système de post-traitement pour poids lourds
This new system combines a Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR). The SCR NOx reduction system injects the correct amount of Diesel Exhaust Fluid (DEF) at the proper rate, thereby decomposing NOx into non-toxic water vapor (H2O) and nitrogen gas (N2).
Arrêt de ralenti automatique Komatsu
Komatsu auto idle shutdown automatically shuts the engine down after idling for a set period of time to reduce unnecessary fuel consumption and exhaust emissions. The amount of time before the engine is shutdown can be easily programmed from 5 to 60 minutes.
Productivité accrue
The PC490LC-11's enhanced P Mode provides more
hydraulic flow and increases productivity.
Productivity
Up to 13% increase
(comparé au PC490LC-10 en mode P standard)
Ventilateur hydraulique à vitesse variable
The electronic control system sets the rotation speed of the cooling fan according to the coolant, hydraulic oil, and ambient temperatures; effectively uses the engine output to reduce wasteful fuel consumption; and reduces noise during low-speed fan operation.
Gabarit de voie variable ( option)
Lateral stability is significantly increased when operating with the gauge extended (compared to fixed gauge). With track frames retracted, overall width complies with many local transportation regulations.
Pompe haute efficacité à grand déplacement
Large displacement hydraulic implement pumps provide high flow output at lower engine RPM as well as operation at the most efficient engine speed.
Équipement de travail à haute rigidité
Booms and arms are constructed with thick plates of high tensile strength steel. In addition, these structures are designed with large cross sectional areas and large one piece castings in the boom foot, the boom tip, and the arm tip. The result is work equipment that exhibits long term durability and high resistance to bending and torsional stress. A standard HD boom design provides increased strength and reliability.
Large cabine spacieuse
The wide spacious cab includes a heated air suspension seat with reclining backrest. The seat height and position are easily adjusted using a pull-up lever. The armrest position is easily adjusted together with the console. Reclining the seat further enables it to be fully laid back with the headrest attached.
Nouvelle conception d 'interface de panneau de moniteur
An updated large high resolution LCD color monitor enables accurate and smooth work. The interface has been redesigned to display key machine information in a new user friendly interface. A rear view camera and an DEF level gauge display have been added to the default main screen. The interface has a function that enables the main screen mode to be switched, thus enabling the optimum screen information for the particular work situation to be displayed.
Points de contrôle moteur centralisés
Locations of the engine oil check and filters are integrated into one side to allow easy maintenance and service.
Interrupteur de déconnexion de batterie
A standard battery disconnect switch allows a technician to disconnect the power supply and lock out before servicing the machine.
Huiles de longue durée, filtres
Haute performance filters are used in the
hydraulic circuit and engine. By increasing
the oil and filter replacement intervals,
maintenance costs can be significantly
reduced.
Moteur oil & Moteur oil filter - every 500 hours
Hydraulique oil - every 5000 hours
Hydraulique oil filter - every 1000 hours
Purificateur d 'air de grande capacité
Purificateur d 'air de grande capacité is comparable to that of larger machines. The larger air cleaner can extend air cleaner life during long-term operation and helps prevent early clogging, and resulting power loss. A reliable seal design is used for reliability.
Réservoir de fluide d 'échappement diesel
A large tank volume extends operating time before refilling and is installed on the right front stairway for ease of access.
Cabine ROPS ( ISO 12117-2)
The machine is equipped with a ROPS cab that conforms to ISO 12117-2 for excavators as standard equipment. It also satisfies the requirements for Level 1 Operator Protective Guard (OPG) and top guard (ISO 10262).
