PC290LC-11

A long reach arm and boom combined with a heavy duty undercarriage provide extended reach with a stable and reliable platform.

Enhanced controller logic and new Tier 4 Final engine technology improve performance and fuel efficiency.

PC290LC-11 Walkaround

Features

Komatsu Auto Idle Shutdown

Komatsu auto idle shutdown automatically shuts the engine down after idling for a set period of time to reduce unnecessary fuel consumption and exhaust emissions. The amount of time before the engine is shutdown can be easily programmed from 5 to 60 minutes.

Fuel Consumption

Reduced by 5%

(vs PC290LC-10 Based on typical work pattern Collected via KOMTRAX)

Heavy Duty Undercarriage and long reach

The PC290LC-11 utilizes a PC360 undercarriage and a heavy long life 11,464 lb counterweight to deliver excellent stability. A long arm with large bore cylinders give the PC290LC-11 a long reach.

Arm rest with simple height adjustment function

A knob and plunger on the armrests allows easy height adjustment without the use of tools.

Switchable Display Modes

The main screen display mode can be changed by pressing the pressing the F3 key.

Operator Identification Function

An operator identification ID can be set up for each operator, and used to manage operation information of individual machines using KOMTRAX data. Data sent from KOMTRAX can be used to analyze operation status by operator as well as by machine.
