Komatsu's PC170LC-10 is new to Europe
By Lindsay Gale16 April 2014
Komatsu has introduced the PC170LC-10 into the European market, with operating weights from 17.3 to 18.2 tonnes, depending on specification. According to the company, it offers up to 5% greater lift capacity with a standard counterweight compared to the PC160LC-8 that it replaces and fitting an optional heavier counterweight provides an increase of up to 15%. The latter, says Komatsu, is ideal for contractors looking for a more powerful lifting machine, combining versatility with power for the widest range of applications.
All of the new excavator’s major components, including the engine, hydraulic pump, motors and valves, are exclusively designed and manufactured by Komatsu. This integrated design employs a closed centre load sensing hydraulic system that takes hydraulic efficiency to the next level, utilising both variable speed matching and low speed matching technology.
Variable speed matching allows the engine speed to adjust based on the hydraulic pump output for both light and heavy-duty applications, while low speed matching utilises a larger pump capable of producing higher pump output at lower engine speeds. Enhanced working modes are designed to match engine speed, pump delivery and system pressure to the application.
The integrated design of the Komatsu Diesel Oxidation Catalyst (KDOC) allows this simple system to remove soot using 100% “true passive regeneration” without the need for a Diesel Particulate Filter (DPF). The KDOC is designed for long life, with no scheduled replacement interval. Less complexity and truly seamless operation for the operator means lower owning and operating costs.
The Komatsu SAA4D107E-2 engine is EU Stage IIIB certified and provides lower emissions and lower fuel consumption. It uses an advanced electronic control system to better manage air-flow rate, fuel injection, combustion and exhaust after-treatment to optimise performance, reduce emissions, reduce fuel consumption and provide advanced diagnostic capability.
