The Komatsu PC500-11 excavator.

Komatsu has sold nearly 180 of its PC5500-11 excavators — a machine it says is designed for “precision, productivity and longevity” for surface mine operators.

The excavator, weighing anywhere from 533 to 552 mt (588-608 st) depending on the configuration, has a twin engine and technology to match with 150-240 st trucks, it said.

“With 179 sold and a total of 7,878,910 operating hours, the PC5500 has become one of the most popular hydraulic excavators with demonstrated reliability as a powerful workhorse with excellent digging forces,” the company said in a press release.

Operator care  a priority

The excavator has been developed and designed to meet the standards of the European Machinery Directive and EMESRT (Earth Moving Equipment Safety Round Table) design philosophies.


Designed with operators in mind, the 45-degree ladder system offers comfortable ascent and descent, and the updated emergency exit system allows ease of egress from two independent locations. For situational awareness around the machine, KomVision can provide the operator an expansive view of the surrounding work area from inside the cab.


A variety of options are available for a machine that is built to meet specific application needs. Komatsu buckets are designed for the industrial standard density of 1,8 t/m³ to meet a wide range of material densities.

To match the demands of your specific material characteristics, it offers a comprehensive variety of buckets ― customized in volume and protection.

A cold weather kit or additional cooler options are available to fit your operation’s global terrain requirements.

Tailored Komatsu’s track pad options will cover your specific underground requirements, such as tar sands or hard rock, to enable excellent conditions for efficient operation with safety a priority.


The PC5500-11 is equipped with two Tier 4 engines — with a focus on sustainability. Its exhaust after-treatment system reduces particulate matter, sulfur oxides and NOx, while offering easy solutions for maintenance intervals, according to Komatsu.

Diagnostics to improve productivity

To limit downtime and promote availability, the PC5500-11’s newly revamped monitoring system, Komtrax Plus 2, helps create automized data reports that identify performance opportunities to help enhance productivity. Machine data is accessible via satellite for instant monitoring.

Critical data to help boost efficiency

The optional Komatsu Argus Payload Meter helps enhance efficiency of truck loading andfleet dispatch. To help maximize productivity, information about the bucket loading status compared to the truck’s capacity provides data to help calculate the best loading times and truck passes.
