If you’re looking for a workhorse excavator you can count on, consider the twin-engine PC 5500. Offering a combination of robust construction, choice of diesel or electric motors, and advanced technology, the PC5500 matches with your 150-240 st trucks.


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.

Hydraulic System

Description: The power train consists of two main drives. Each of the two gearboxes drives three identical main pumps which draw hydraulic oil from an unpressurized hydraulic tank. Open circuit hydraulics provide maximum cooling and filtering efficiency.

Flow description: The four-circuit systems feature a load-limiting governor with oil delivery summation to the working circuits and incorporates pressure cut-off control. Hydropilot priotieses hydraulic flow giving smooth hydraulic response, simple hydraulic system layout, and a reduced number of components. The hydraulic system includes large swing-out vertical air-to-oil hydraulic coolers with temperature-regulated hydraulically driven fans.

Automatic Lubrication System

Description: Three hydraulically powered Lincoln single line automatic lubrication systems are provided as standard, complete with time and volume variable controls. The two central lubrication circuits and open gear grease circuit are supplied by identical pump assemblies from refillable containers which have a capacity of 1x 600 and 1x 300 L (total 238 gal). Replenishment of the containers is through the Wiggins connections on the service arm.

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).
