Construction Equipment Outlook: Komatsu PC45MR

The construction equipment industry is projected to grow 12% from 2016 to 2026. Excavators are powerful machines that are integral for all kinds of construction-related projects. Without excavators, millions of construction tasks around the world would be compromised and potentially never even reach completion.

Excavators come in three sizes: compact (mini), mid-size (midi), and large. Let's take a look at two Komatsu excavators: the PC45MR and the PC50MR.

Komatsu PC45MR

This tight-tail-swing compact excavator is great for general contractors performing contraction-related tasks. It fits on an 80-inch deck trailer, can be easily transported, and delivers powerful performance. Equipped with a clean engine, this excavator can actually provide environmental benefits, as it complies with the EPA's Tier 4 Final emissions regulations. Its engine utilizes eco-friendly technologies, including an electronically-controlled cooled Exhaust Gas Recirculation (EGR) system, optimum fuel injection system using a common rail, and an exhaust gas after treatment system. By utilizing these innovative technologies, the PC45MR can not only perform powerful excavating tasks, but can reduce up to 5% fuel consumption, as well.

Here are some of the important specifications of the PC45MR:

  • Type -- Water-cooled, 4-cycle, direct injection, cooled EGR

  • Aspiration -- Naturally aspirated

  • Stroke -- 90 millimeter 3.54"

  • Piston displacement -- 2.19 ltr

  • Rated RPM -- 2,400

  • Governor -- All-speed control, electronic

  • Steering control -- Two levers with pedals (hydrostatic drive method)

  • Travel speed -- 1.6 to 2.9 MPH

Additionally, the Komatsu PC50MR is another great machine. For individual construction workers and smaller organizations that need to dig holes for various reasons, the PC50MR is ideal. This excavator is small enough that it can be hauled behind a mid-size pickup truck and perform all sorts of construction and landscaping tasks.

It's important to note, however, that hydraulic travel motors are extremely important for excavators.
