The PC290LC-11 is a mid-size hydraulic excavator built for extended reach with a long reach arm and boom, supported by a robust undercarriage. Here are some key features:
- Large high-strength steel castings on the boom, arm, and bucket link for durability.
- Closed-center load-sensing hydraulics for precise and fine control.
- Large displacement high-efficiency pumps to optimize attachment flow.
- Spacious and quiet cab featuring a standard air suspension seat for operator comfort.
Product Features and benefits:
Efficient Hydraulic System
Large displacement hydraulic implement pumps ensure high flow output at lower engine RPM, promoting operation at the most efficient engine speed.
Advanced Hydraulic Operation
Experience smooth operation, quick cycle times, and versatile multi-functionality with the closed-center load-sensing hydraulic system. This innovation effectively lowers fuel consumption while enhancing overall excavator performance.
Built to Last
Designed for long-term durability, the excavator boasts high resistance to bending and torsional stress. Thick plates of high tensile strength steel construct booms and arms, featuring large cross-sectional areas for robust construction.
Environmental Responsibility
Addressing environmental concerns, the heavy-duty aftertreatment system combines a Komatsu Diesel Particulate Filter (KDPF) and selective catalytic reduction (SCR). It efficiently injects the correct amount of diesel exhaust fluid to decompose nitrogen oxide, resulting in cleaner emissions.
Convenient Maintenance Access
Engine oil check and filter locations are intelligently integrated into one side, ensuring easy access for maintenance tasks and minimizing downtime.
Ergonomic Excellence
The advanced ergonomic design prioritizes operator comfort. The excavator’s wide, spacious cab includes a heated air suspension seat with a reclining backrest. Adjustable seat height and position, along with easily maneuverable armrests, contribute to a comfortable working environment.
Information Hub
Stay informed with an updated, large, high-resolution LCD color monitor that provides key machine information in a user-friendly interface. Features such as a rearview camera and DEF level gauge display are added to the default main screen.
Safety First
Rollover protection is guaranteed with a ROPS cab conforming to ISO 12117-2 standards. It satisfies requirements for level 1 operator protective guard (OPG) and top guard (ISO 10262), ensuring a secure working environment.
Enhanced Productivity
Implementing multi-operator productivity features, an operator identification ID can be set up for each operator. This data is then used to manage operation information, allowing analysis of operation status by both operator and machine.
Fuel Efficiency Management
Reduce fuel consumption and minimize exhaust emissions with the auto idle shutdown feature. The engine automatically shuts down after idling for a set period, programmable from 5 to 60 minutes.
Durability and Maintenance Ease
Designed for durability, large heavy-duty revolving frame guards and a swivel guard protect vital components from damage and debris build-up. Additionally, a new step provides easier access for filling the AdBlue/DEF tank, contributing to overall maintenance ease.
