Komatsu’s short-tail swing excavator builds on Komatsu’s proven technology of the previous model and includes hydraulic system enhancements, improved operator control and comfort, excellent lift capacity and stability, and lower fuel consumption. The PC228USLC-10, with an operating weight between 23,800 kg and 24,500 kg, is powered by a net 123 kW (165 HP) Komatsu SAA6D107E-2 engine that is EU Stage 3B tier engine.
More compact than a conventional excavator, the PC228USLC-10 tail allows the machine to work in confined areas for road, bridge, and urban applications. The rounded cab design allows the cab to rotate within the same swing radius as the counterweight. The sliding cab door allows unrestricted access / egress to the cab in confined spaces. The PC228USLC-10 is supported by KomatsuCARE, a complimentary maintenance program for Komatsu customers that comes as standard with every new Komatsu Stage 3B construction machine. For the first three years or 2.000 hours it covers factory-scheduled maintenance, performed by Komatsu-trained technicians with Komatsu Genuine parts. Komatsu CARE offers up to a maximum of two complimentary Komatsu Diesel Particulate Filter (KDPF) exchanges and a KDPF warranty for the first five years or 9.000 hours.
The latest KOMTRAX™ technology on the PC228USLC-10 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.
EU Stage Stage 3B Certified Engine
The PC228USLC-10 uses a Komatsu EU Stage 3B certified engine. Built upon Komatsu’s proven Stage IIIA technology, the SAA6D107E-2 engine provides a 6.7% increase in horsepower whilst lowering fuel consumption. Using an advanced electronic control system to manage airflow rate, fuel injection, combustion parameters, and after treatment functions, the Komatsu EU Stage 3B engine optimizes engine performance, reduces emissions, and provides diagnostic capability. A hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and Exhaust Gas Recirculation (EGR) valve provide improved precision and air management as well as longer component life. The Komatsu Diesel Particulate Filter (KDPF) design provides virtually 100% passive regeneration using normal engine exhaust temperatures to clean out the filter and therefore does not interfere with daily operation. To ensure product reliability and durability in demanding conditions, Komatsu developed the entire system, including the control software that is critical to the effective operation of the after treatment system. This control system is also integrated into the machine’s on-board diagnostics systems and KOMTRAX™, Komatsu’s standard telematics system.
All major components on the new PC228USLC-10 including the engine, hydraulic pumps, motors, and valves are exclusively designed and produced by Komatsu. Using a Closed Center Load Sensing (CLSS) system, the hydraulic system of the PC228USLC-10 was enhanced to increase efficiency, lower hydraulic loss and fuel consumption. New engine and hydraulic pump control technology improves operational efficiency, speed and productivity whilst lowering fuel consumption by up to 4% over the previous model. Enhanced Operating Efficiency through Ease of Maintenance and Serviceability The PC228USLC-10 has ground level access to key service points. The fuel drain valve, engine oil filter, swing machinery and pump drive oil filters are all remote-mounted for easy maintenance. The radiator, hydraulic oil cooler, and charge air cooler are mounted side by
side, making it simple to maintain and service. The excavator is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which performs three main functions, displayed on the large LCD colour monitor. EMMS continually monitors all critical excavator systems, alerting and guiding the operator should an abnormality occur. DT-type electrical connectors seal against dirt and moisture. For additional reliability, metal guard rings protect all hydraulic cylinders. Hydraulic hoses are equipped with O-ring seals versus conventional taper seals to help prevent leaks. Long replacement intervals for hydraulic oil, engine oil and filters reduce maintenance time for added production ready hours.
Cab Enhancements Provide Comfortable Working Environment
The ROPS-certified cab, specifically designed for hydraulic excavators, gains strength from a reinforced box structure framework. The spacious cab is pressurized and is equipped with a standard heated, air suspension high back operator seat for excellent support and comfort for reduced fatigue. The standard high capacity automatic heater/defroster/air conditioning system is incorporated into the monitor panel. The radio has a remote mounted auxiliary input for connecting external devices to play music through stereo cab speakers. Additionally there are two 12-volt power ports incorporated into the cab and a seat base mounted auxiliary engine shut off switch.
