Komatsu launches PC490LC-11 excavator

Komatsu’s new PC490LC-11 excavator with an operating rate between 105,670lbs and 110,220lbs has a net 359 hp and meets EPA Tier IV Final emissions.

This new PC490LC-11 leverages Komatsu’s leadership in technology and innovation by delivering a more environmentally friendly engine that provides high levels of performance while reducing fuel consumption up to 7 percent, according to the manufacturer.

The PC490LC-11 has the latest KOomtrax remote monitoring technology with data access via the web or via smart phone.  In addition to providing data such as fuel levels, operating hours, location, cautions and maintenance alerts, KOMTRAX has been further enhanced to monitor AdBlue/DEF levels, ambient air temperatures and pressures. A new operator identification system reports key operating information for multiple operators.

A new auto idle shutdown function helps improve operating costs by reducing unnecessary idle time.

By integrating selective catalyst reduction (SCR), the Tier IV Final engine further reduces NOx emissions using AdBlue/DEF. The Komatsu Tier IV Final engine uses an advanced electronic control system to manage the air-flow rate, fuel injection, combustion parameters, and after treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability.

The result is 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 more precise temperature and air management control as well as 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 also is integrated into the machine’s on-board diagnostics systems and KOMTRAX, Komatsu’s standard telematics system.

The PC490LC-11 continues to feature a heavy-duty undercarriage and counterweight to maintain the same high lift capacity and lateral stability as the prior series. The operator can easily select lift mode, which raises hydraulic pressure to increase lifting force up to 7 percent.

Along with the high lift capacity, other reinforced components are maintained such as strengthened undercarriage components, a reinforced revolving frame, and a high capacity swing bearing. A variable track gauge option significantly increases lateral stability and lift capacity up to an additional 10 percent.

Additional enhancements have been made within the hydraulic system to reduce hydraulic loss, resulting in better efficiency. A hydraulically driven reversible cooling fan varies fan speed in response to coolant, hydraulic oil, and ambient air temperatures, resulting in better efficiency and a quiet work environment for the operator.

The PC490LC-11 cab provides a comfortable and quiet work environment to help operators maximize productivity. 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 that provide low vibration levels. A standard air suspension high back seat with newly designed fully adjustable armrests is heated for improved comfort. In addition to the standard radio, there is an auxiliary input for connecting external devices to play music through the cab speakers. Moreover, there are two 12-volt power ports incorporated into the cab. Optional joysticks are available with proportional controls for operating attachments.

The PC490LC-11 provides easier service access to help reduce costly downtime. The new model has guardrails on both sides of the upper structure for easier accessibility. The hydraulically driven fan can be manually reversed to simplify cleaning the cooling assembly. The radiator and hydraulic oil coolers are mounted side by side, making it easier to maintain and service when required.

The excavator has Komatsu equipment management monitoring system, which has diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities.
