Komatsu Europe International N.V. introduces the Demolition Specification Dash 11 hydraulic excavators to the European market. This new range was introduced at bauma 2016 in Munich (April 10-17), represented by the PC360NLC-11 Demolition Specification hydraulic excavator. Fully developed and manufactured in-house by Komatsu, these rugged new machines bring optimal durability, while maximizing safety and offering reduced operating costs. Komatsu’s environmentally friendly EU Stage IV compliant engines are used throughout, with the new machines offering up to 5% improved fuel efficiency, an upgraded cab design and enhanced safety and serviceability.

Built on proven EU Stage IIIB engine technology, Komatsu’s EU Stage IV engines are productive, dependable and efficient. With powers ranging from net 123 kW (165 hp) at 2,000 rpm for the PC210LC-11 Demolition Specification Excavator through to net 270 kW (362 hp) at 1,900 rpm for the PC490LC-11 Demolition Specification Excavator, the new machines maintain the powerful performance of the previous Komatsu models. Operating weights range from 23,170 kg for the PC210LC-11 Demolition Specification Excavator through to 4,8835 kg for the PC490LC-11 Demolition Specification Excavator. The PC360NLC-11 Demolition Specification Excavator displayed at bauma weighs in at 36,200 kg.

Simon Saunders, Product Manager at Komatsu Europe International states, “These new excavators offer all of the advantages of the standard Dash 11 machines, but additionally comply with all the special regulations which cover machines used for demolition. The machine on display at bauma additionally features a factory installed tool control system allowing easy adjustment of the hydraulic performance to match the installed demolition tool.”

Key features of the Dash 11 Demolition Excavators

Komatsu factory fitted demolition features

The range of demolition specification excavators include a wide range of features, developed, tested and proven by the Komatsu factory. The Operator Protective Guards fully comply with ISO10262 Level 2 and additionally feature re-designed protective grids to offer exceptional visibility. A roof window wash/wipe system is fitted as standard, while both roof window and front window include high impact protection EN356 Grade P5A glass. The structure of the demolition excavators is significantly reinforced compared with the standard machines, featuring unique upper structure with factory installed protective side guards and heavy-duty undercovers. A variety of boom and arm lengths are available, including straight booms for some models, as highlighted by the PC360NLC-11 machine at bauma.

Komatsu EU Stage IV emission certified engine – Productive, dependable, efficient

Komatsu’s new EU Stage IV engines integrate 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 engines optimize performance, reduce emissions and provide advanced diagnostic capability. Customers benefit from 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 new Dash 11 Demolition Specification Excavators feature a heavy-duty undercarriage and maintain the same high lift capacity and lateral stability as the prior models. The operator can easily select Lift Mode to raise hydraulic pressure and increase lifting force by up to 6%.

Highly efficient hydraulic system

Enhancements were made to the hydraulic system for reduced hydraulic loss and better efficiency. All major components, including the engine, hydraulic pumps, motors and valves are exclusively designed and produced by Komatsu. This integrated design uses a closed center load sensing hydraulic system that takes hydraulic efficiency to the next level using variable 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.

Operator environment

The Dash 11 operator cab provides a comfortable and quiet work environment that helps operators maximize productivity. The 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 12V power ports for the operator’s convenience.

A high-resolution 7 in. LCD widescreen color monitor features enhanced capabilities and displays information in 26 languages for global support. The operator can easily select up to six working modes to match machine performance to the application. The new monitor panel provides information on AdBlue fluid level, Eco guidance, operational records, fuel consumption history and utilization information. For improved safety, a standard rear-view camera gives the operator a wide landscape view of the area directly behind the machine and is now incorporated, along with the gauges, as the operating default screen. An optional second camera is available.

Convenient maintenance and serviceability

Easier service access is provided to help reduce costly downtime. The new model has guardrails on both sides of the upper structure for easier accessibility. The radiator and hydraulic oil coolers are mounted side by side, making it easier to maintain and service when required.

The new excavators are equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which has enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS also continuously monitors all critical systems, preventative maintenance, and provides troubleshooting assistance to minimize diagnosis and repair time.

KOMTRAX telematics and Komatsu Care, a complimentary maintenance program, offer top fleet management and support, protect the machine against misuse and guarantee maximum efficiency and uptime.

“With Komatsu CARE, customer peace of mind also comes as standard,” says Jim Venerus, Deputy General Manager for Marketing. “This industry exclusive keeps your new EU Stage IV machine up and running, smoothly and efficiently, and gives truly unbeatable customer value.”
