Komatsu PC490HRD-11EO

This high reach demolition excavator is built for controlled dismantling work

This Komatsu high reach demolition excavator is intended for planned dismantling of taller structures. The machine supports controlled material removal where reach, visibility and attachment control are critical. Its operating weight is 75,830 kg, which places it in a class suited to demanding demolition contracts. The high reach boom gives the machine a role in projects where standard excavators do not provide enough vertical working range.

The overall length is 23,170 mm, the width is 2,980 mm, and the construction height is 3,600 mm. These dimensions matter when planning transport, site access and machine setup. For contractors working across varied demolition sites, this information helps assess space requirements before the machine arrives on location.

The machine supports stability and positioning during demolition tasks

An extendable hydraulic undercarriage allows the width to change from 2,980 mm to 3,980 mm. This gives a wider working stance when the machine is set for demolition. A narrower transport width also helps when the machine must move between projects under controlled logistics conditions.

Skidsteer steering supports positioning in confined site areas where precise movement is required. In demolition work, controlled placement is important for both reach and safety. The undercarriage setup supports this need by combining transport practicality with a wider base during operation.

The cab layout is made for visibility and operator control

The cab includes heating, climate control and joystick operation. It also has an outer rear view mirror, a large parallel front wiper and a 30 degree tilting cab. These features support the operator when the boom is raised and work is carried out at height.

The air suspended Grammer Evolution seat includes damping, ventilation and heating. In demolition applications, the operator spends long periods monitoring attachment movement and surrounding conditions. A cab layout with clear visibility and stable seating supports this kind of precise machine control.

Hydraulic functions support attachment changes and controlled tool use

The hydraulic setup includes hydraulics for a quick coupler and a pressure keeping valve on the boom. The machine also has the Komatsu K100 boom change system. This supports planned changes between work setups when project phases require different boom arrangements.

The Komatsu Tool Control System allows settings for oil pressure and oil flow. This is relevant when the excavator works with different demolition attachments that need defined hydraulic input. Drain lines for equipment are also included, which supports attachment use where return flow handling matters.

Safety systems support work in exposed demolition environments

The machine is equipped with a work area indicator with visual display and audible alarm. For demolition sites, this supports awareness of the machine working zone during operation. ISO 10262 level 2 OPG guards are fitted on the front window and roof. Impact resistant glass to EN356 Grade P5A is also specified.

KomVision camera equipment improves external machine visibility. A back up alarm, rotating beacon and extensive LED work lights support operation during low light conditions and on complex sites. The light package includes boom lights, roof mounted forward lights, side lights and rear lighting on the roof and counterweight.

The powertrain and machine protection support daily site operation

The Komatsu engine setup includes automatic idle, autostop, diesel particulate filter and SCR with AdBlue. A reversible fan is fitted, along with a diesel filling pump with autostop. These features support daily machine use where service planning, emissions handling and cooling management are part of normal operation.

Komtrax monitoring is included for machine follow up. The upper structure also has bolted side plates for protection of the frame sections, along with heavy duty bottom plates. For contractors assessing a demolition excavator, these details give a clear picture of a machine designed for controlled high reach dismantling and attachment based work.
