The PC490LC-10 High Reach Demolition (HRD) excavator is an addition to Komatsu’s highly successful demolition range. The PC490LC-10 HRD, which was on display at Intermat 2015 in Paris (April 20-25), brings the benefits of the Dash 10 range into the specialised demolition industry and is ideally suited for the demolition of heavy industrial structures. This original Komatsu factory equipment was developed over 2,5 years and has received full OEM quality assurance after passing stringent performance tests.
Weighing in at 65.950 kg, the PC490LC-10 HRD is powered by a Komatsu SAA6D125E-6A engine with a flywheel horsepower of 270 kW (362 HP) and is compliant with EU Stage IIIB emissions regulations.
“The new PC490LC-10 High Reach machine is developed and manufactured specifically for European customers” says Simon Saunders, Product Manager for Working Gear. “The new heavy duty medium reach specification, coupled with the range of new features, allows the owner and operator to maximise safety, productivity and, ultimately, profitability.”
New Features:
Designed for demolition
Designed, manufactured, tested and supported by Komatsu, the PC490LC-10 HRD excavator is purposely built for demolition work: it has a large working range with a maximum working height of 28 m. The large diameter boom cylinders ensure the operator has maximum hydraulic power at all times for total control, even at extreme reach. Its “Best in Class” demolition tool capacity of 3,35t at 16,5m forward reach improves project time and helps to reduce machine loading. A new heavy duty medium reach demolition specification allows the use of full size 5t demolition tools at a height of up to 17,4 m, giving the new machine the capability to tackle heavy demolition work at medium height. The PC490LC-10 HRD is compliant with latest EU474 Annex G regulations which govern machines used for cutting buildings.
Enhanced safety features
The new working range indicator system does not interfere with the control of the machine. It gives full colour, real time indication of the precise position of each section of the work equipment, to ensure the operator is fully aware of the available working range. The system includes memory settings for 15 attachments (with operator selectable names) and takes into account the inclination of the base machine for calculation of the available working range. The system is effective for both high reach and medium reach demolition, automatically detecting which equipment configuration is installed at engine start up. The cab is specifically designed for the new high reach demolition excavator. The front window and roof window incorporate high impact protective glass compliant with EN356 Grade P5A. The front guard, side hinged for easy window cleaning, complies with ISO10262 Level 2 falling object test requirements.
Enhanced operator environment
The PC490LC-10 HRD operator cab is mounted on a Komatsu original tilting mechanism, the tilt angle being infinitely adjustable between 0 and 30o, with convenient tilt angle control through joystick-mounted thumb switches. The fully air suspended operator control station incorporates side consoles mounted together with the high back, fully adjustable seat, with standard-fit heating for improved comfort. The cab provides a comfortable and quiet work environment where operators can maximise their productivity. It gains strength from a reinforced tubular skeleton framework. Viscous damper mounts lower vibration levels, further enhancing fine control and reducing operator fatigue. Along with two 12 volt ports, an auxiliary input has been added to connect an MP3 player or other device that uses a standard auxiliary.
Convenient maintenance and serviceability
Newly designed work equipment stands with integrated access platforms cut down the time taken to change the configuration of the machine and significantly increase the safety of the changeover process. Tie down lugs are provided allowing the high reach equipment to be transported while located in the equipment stands, improving ease of transportation. The PC490LC-10 HRD provides easy service access that reduces costly downtime. Routine service points are quickly reachable from ground level and handrails surround the accessible areas of the upper structure for easier and safer checking and maintenance. The radiator and hydraulic oil cooler are mounted side by side, making it simpler to carry out maintenance and service when required, while the air conditioning condenser is hinged to allow even easier access. Access steps are provided in all naturally convenient positions to allow safe and quick access to the engine bay. The machine is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which has enhanced diagnostic features that give operators and technicians greater monitoring and troubleshooting capabilities. EMMS also continuously monitors all critical systems and preventative maintenance, and provides assistance to minimise diagnosis and repair time.
EU Stage IIIB / EPA Tier 4 Interim emission certified engine
The Komatsu SAA6D125E-6A engine uses an advanced electronic control system to manage airflow rate, fuel injection, combustion parameters, and aftertreatment functions to optimise performance, reduce emissions and provide advanced diagnostic capability. As a leader in hydraulic technology, Komatsu developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, resulting in up to 5% reduction in fuel consumption, as well as longer component life. The passive/active Komatsu Diesel Particulate Filter (KDPF) is designed to function primarily in its highly efficient “passive” mode and oxidises most trapped particulates with no need for operator control and no interruption to machine operations. Based on exclusive Komatsu technology, this regeneration system keeps the operator aware of its status and has a manual override integrated into the monitor panel.
The latest KOMTRAX™ technology on the PC490LC-10 HRD 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.
The PC490LC-10 HRD comes with Komatsu CARE™, a complimentary maintenance program for Komatsu customers. 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 2 complimentary KDPF exchanges and a KDPF warranty for the first 5 years or 9.000 hours.
