The All-New Komatsu PC210/LC-11 hydraulic excavator

Komatsu has just announced the introduction of the PC210/LC-11 tracked excavator to the European market with latest technology innovations and an environmentally friendly EU Stage IV Komatsu engine delivering up to 6% improved fuel efficiency.

Other features include an upgraded cab design and enhanced safety and serviceability. Productivity is maximised and operating costs are reduced.

Replacing the Series 10 model, the latest model is built around the Komatsu’s EU Stage IV final engines.

The new engine delivers the same net power of 123 kW (165 HP) @ 2.000 rpm and is in the same operating weights between 22.120 kg – 23.580 kg.

Where the latest model improve is explained by Vince Porteous, Product Manager at Komatsu Europe International states:

This new excavator does so much more than simply meet EU Stage IV emission regulations: it offers significant advances in fuel consumption, provides 3G communications, improves operator comfort and includes new safety features.

Komatsu EU Stage IV emission certified engine integrates SCR to further reduce NOx emissions using the AdBlue additive. With an advanced electronic control system that manages the airflow rate, fuel injection, combustion parameters and aftertreatment functions, the Komatsu EU Stage IV engine optimises performance, reduces emissions and provides advanced diagnostic capability.

For the customer, this means lower fuel consumption with no loss of performance.

Komatsu continues to use a Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve for precise temperature and air management control and for longer component life.

To ensure product reliability and durability in demanding conditions, Komatsu developed the entire system, including the control software, which is critical to the effective operation of the aftertreatment system.

This control system is also integrated into the machine’s on-board diagnostics systems and in KOMTRAX, Komatsu’s standard telematics system.

Lift capacity and stability

The PC210/LC-11 features a heavy-duty undercarriage and maintains the same high lift capacity and lateral stability as the prior PC210 model.

The operator can easily select Lift Mode to raise hydraulic pressure and increase lifting force by up to 7%.

Enhancements have been made to the hydraulic system for reduced hydraulic loss and better efficiency and all major components, including the engine, hydraulic pumps, motors and valves are exclusively designed and produced by Komatsu.

This integrated design uses a closed centre load sensing hydraulic system that takes hydraulic efficiency to a higher level using variable speed matching. This technology allows the engine speed to adjust according to the hydraulic pump output for both light and heavy-duty applications.

Operator environment

For the past decade or more, every new machine has promised improved operator comfort and environment. This is made possible by new materials but is also more necessary than times past. Operators today can spend the full working day in the cab and that is very demanding on the body so ergonomics become much more important.

The cab on this new Komatsu adds improvements. The in-cab noise is a very low 67 dB(A). This has been achieved by a new fan clutch system that controls optimal fan speed. Not only reducing noise but also reducing fuel consumption.

Proportional control joysticks, which are standard, allow precise operation of attachments with comfort and ease. With the addition of the new Neutral Detection System, the risk of inadvertent operation is reduced.

The ROPS certified cab, specifically designed for hydraulic excavators, gains strength from a reinforced box structure framework. The cab is mounted on viscous isolation dampers for low vibration levels.

A standard heated high back air suspension seat comes with newly designed fully adjustable armrests for improved comfort. In addition to the standard radio, external devices can play music through the cab speakers thanks to an auxiliary input.

The cab also has the benefit of two 12-volt power ports for the operator’s convenience.
