Komatsu PC490LC-11EO

Komatsu PC490LC-11EO is built for demanding excavation work

Komatsu PC490LC-11EO is a crawler excavator for heavy digging, material handling and site preparation. The operating weight is 48,860 kg. This machine uses a mono boom and a skidsteer travel layout. That setup supports direct control during excavation, loading and repositioning on site.

The machine length is 11,930 mm and the width is 3,790 mm. Construction height is 3,635 mm. These dimensions matter when planning transport, access and working space on larger construction projects. The size and weight make this excavator relevant for contractors handling substantial ground volumes.

The boom and hydraulic layout support controlled attachment use

The mono boom gives a familiar excavator geometry for general earthmoving and structured digging cycles. It suits trenching, bulk excavation and loading work where stable boom movement is required. The hydraulic setup includes lines for a quick coupler. That supports attachment changes when tasks shift during the working day.

Hydraulic pressure keeping valves are fitted on both boom and stick. These functions support controlled holding during lifting and handling tasks. The machine also includes HCU C hydraulics on the stick arm. HCU C hydraulics are also fitted on the mono boom.

Komatsu Tool Control System is installed on one circuit for oil pressure and oil flow control. This is relevant when the excavator is used with hydraulic attachments that need defined settings. It gives a clearer basis for matching the machine to attachment driven work.

The undercarriage supports stability across changing work conditions

The undercarriage is mechanically extendable from 3,290 mm to 3,790 mm. This configuration supports adaptation between transport related needs and working stability on site. For excavation contractors, track width has direct importance for machine stance and usable footprint.

On larger jobs, this can support steady machine behaviour during digging and lifting. It also helps when the excavator works with attachments that place changing loads on the front equipment. The crawler layout remains a practical choice for uneven terrain, prepared platforms and active earthmoving areas.

The cab is configured for long working days

The cab includes heating, climate control and joystick operation. An outer rear view mirror is fitted. The seat is an air suspended Grammer Evolution unit with damper, ventilation and heating. These details support the operator during long shifts where clear control input and stable seating matter.

The cab also includes a DAB+ radio with Bluetooth and external microphone. A lower front window wiper is fitted. These details are relevant for daily operation, communication and visibility in mixed weather conditions. The layout reflects practical requirements on larger sites with extended machine use.

The engine and safety equipment support structured site operation

The engine setup includes automatic idle, autostop, a diesel particulate filter and SCR with AdBlue. A diesel filling pump with autostop is also included. These features describe how the machine is configured for routine operation and fuel handling on site.

Safety and visibility equipment includes a back up alarm and KomVision camera system. A rotating beacon is fitted. The machine also has eight LED work lights facing forward, with LED lighting elsewhere on the machine. This improves visibility around the excavator during early starts, late shifts and work in restricted light conditions.

For companies assessing a heavy crawler excavator, these facts provide a clear basis for comparing application fit, attachment control and site handling requirements.
