PC228US-LC-8 Komatsu excavator specs & Dimensions (2007 - 2014)

Continuous Machine Monitoring System

When the starting switch is turned ON, check-before-starting items and caution items appear on the LCD. If abnormalities are found, a warning lamp blinks and a warning buzzer sounds. Continuous machine condition checks help prevent the development of serious problems and allow the operator to concentrate on the work at hand.

Abnormalities Display with Code

When an abnormality occurs during operation, a user code is displayed. When an important user code is displayed, a caution lamp blinks and a warning buzzer sounds to alert the operator to take action.

Low Fuel Consumption

The Komatsu SAA6D107E-1 engine enables NOx emissions to be significantly reduced with the accurate multi-staged fuel injection by the engine controller. It improves total engine durability using the high pressure fuel injection system developed specifically for construction machinery. This excavator significantly reduces hourly fuel consumption using the highly-efficient matching techniques of the engine and hydraulic systems and also provides features that promote energy-saving operations such as Economy mode and the Eco-gauge.

Low Emission Engine

The Komatsu SAA6D107E-1 is EPA Tier 3 and EU stage 3A emissions certified and reduces NOx emission by 29% when compared with the PC228USLC-3.

Low Operational Noise

The PC228USLC-8 enables low noise operation using a low-noise engine and methods that reduce noise at the source. Electronically controlled common rail type engine Multi-staged injection Highly-rigid cylinder block Low noise design Sound absorbing materials Partition between the cab and engine room.

Low Cab Noise

The newly-designed cab is highly rigid and has excellent sound absorption ability. Improvement of noise source reduction and use of low noise engine, hydraulic equipment, and air conditioner allow this machine to generate a low level of noise similar to that of a modern automobile.

New Cab Design for Hydraulic Excavators

The cab is designed specifically for hydraulic excavators and gains reinforced strength from the pipe-structured cab framework. The cab framework provides high durability and impact resistance with very high impact absorbency.

Walk-Around

Komatsu's PC228USLC-8 Hydraulic Excavators have a short tail swing profile, designed specifically for work in confined areas. By reducing the tail swing, the PC228USLC-8 is perfect for work on roadways, bridges, urban areas, or anywhere space is limited. The PC228USLC-8 provides the performance and productivity you expect from Komatsu equipment.

Reliable Components

All of the major machine components, such as engine, hydraulic pumps, hydraulic motors and control valves are Komatsu designed.

Working Mode Selection

The PC228USLC-8 excavator is equipped with five working modes (P, E, L, B, and ATT). Each mode is designed to match engine speed, pump flow, and system pressure with the current application. This provides the flexibility to match equipment performance to the job at hand.

Easy Maintenance

Komatsu designed the PC228USLC-8 to have easy service access. By doing so, routine maintenance and servicing are less likely to be skipped, which can mean a reduction in costly downtime later on. Here are some of the many service features found on the PC228USLC-8.

Optimum Maintenance Layout

With the left and right side service doors, it is possible to access the major maintenance points from ground level. Furthermore, the fuel drain valve, engine oil filter, swing machinery oil filler, and PTO oil filler are remote mounted, facilitating easy maintenance.

Side-by-side Cooling

Since the oil cooler, aftercooler and radiator are arranged side-by-side, it is easy to clean, remove, and install them.

Eco-white Filter Element

High performance filters are used in the hydraulic circuit and engine. Longer replacement intervals for the hydraulic oil, hydraulic oil filter, engine oil and engine oil filter element significantly reduce maintenance costs.

Self-Diagnostic Monitor

The PC228USLC-8 features the most advanced diagnostics system in the industry. The Komatsu-exclusive system identifies maintenance items, reduces diagnostic times, indicates oil and filter replacement hours, and displays error codes.

Oil Maintenance Function

When the machine exceeds the oil or filter replacement time, the oil maintenance monitor will display lights to inform the operator.

High Rigidity Work Equipment

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 generous use of castings. The result is working attachments that exhibit long term durability and high resistance to bending and torsional stress.

Lock Lever

When the lock lever is placed in lock position all hydraulic controls (travel, swing, boom, arm and bucket) are inoperable.

Multi-position Controls

The multi-position, Pressure Proportional Control (PPC) levers allow the operator to work in comfort while maintaining precise control. A double-slide mechanism allows the seat and controllers to move together or independently, allowing the operator to position the seat and controllers for maximum productivity and comfort.

Comfortable Ride with Viscous Cab Mounts

Viscous mounts are used for the cab mount system. The cab mount system absorbs shocks and reduces vibration to provide a comfortable ride.

Pressurized Cab

Automatic air conditioner, air filter, and a higher internal air pressure minimize the amount of external dust that enters the cab.

Wide Newly-designed Cab

Large cab provides ample operation space and includes a high-back seat. The cab has a wide doorway for easy access.

Automatic Air Conditioner

Enables you to easily and precisely set cab atmosphere with the instruments on the large LCD. The bi-level control function keeps the inside of the cab comfortable from top to bottom throughout the year. Defroster function keeps cab glass clear.

Large Multi-Lingual LCD Monitor

A large user-friendly color monitor enables accurate and smooth work. Screen visibility is improved by using a TFT liquid crystal display that can easily be read at various angles and lighting conditions. All switches are simple and easy to operate. Industry-first function keys facilitate multi-function operations. Data can be displayed in 12 languages to globally support operators around the world.
