Features and benefits

Safeguard your operators and work site

Operator and work site safety are a priority. Komatsu hydraulic excavators have an LED screen to give your operator a 360-degree view, each meet ISO 10262, 6394, 10263-4 safety stand-ards, and all include anti-slip gratings, easy ingress/egress and an innovative emergency es-cape system.

Customized to your operation

While Komatsu shovels and backhoes meet the density benchmark of 1.8 t/m³, you have the option to customize your machine to the bucket size and wear package you need, and choose your heating/cooling systems, travel gear protections, special track pad variations and more.

Sustainable, powerful engines

Tier 4 engines deliver plenty of power with outstanding sustainability. An exhaust after-treatment system reduces particulate matter, sulfur oxides and dangerous NOx, and easy servicing of emissions components.

Diagnostics to help improve productivity

To improve productivity and limit downtime, you need accurate, reliable machine data. The exca-vator’s newly revamped monitoring system helps you dial in efficient machine movement, quickly identify opportunities to improve productivity, and troubleshoot any issues quickly.

Critical data to help boost efficiency

A built-in payload meter helps you optimize the efficiency of your truck traffic flow and your fleet. Knowing just how much load is in the bucket versus your trucks’ capacity gives you data you need to calculate optimal loading times and truck passes for maximum productivity.

Komtrax plus

Version: Komtrax Plus 2

Description: The Komtrax Plus monitoring system is designed for Komatsu mining equipment to provide real time and stored
information about the operating status of the machine. Fault messages are immediately available to the operator via
a digital display and in the event of critical malfunctions the engine is also shut down. The digital storage provides
failure summary and analysis, which can be down loaded by laptop computer. This data will assist in predicting or
reduction downtime. Optionally available is Orbcomm satellite transmission (check for availability in your territory).
