Even the most complex projects can be completed on time and under budget if you have an excavator that is up to the task. That’s why companies around the world rely on Komatsu PC55MR-5 mini excavators. Designed with power in mind, this compact yet incredibly strong excavator gives you the ability to do more work while using less fuel. That means more done, on time and under budget!

New Komatsu PC55MR-5 Mini Excavators Get the Job Done on Time and Under Budget With More Power, Greater Control and Improved Fuel Efficiency

The new Komatsu PC55MR-5 mini hydraulic excavator delivers more power, greater control and improved fuel efficiency, helping customers complete their jobs on time and under budget.

“The new PC55MR-5 features a newly designed Komatsu SAA4D95LE-7 engine that meets U.S. EPA Tier 4 Final/EU Stage IV emission standards,” said Jason Suchy, product manager for Komatsu’s small excavators. “The engine produces more horsepower (net: 21 kW 28 HP) and has a lower minimum operating speed than the previous model. This provides more versatility in a wider variety of applications.”

Due to its low center of gravity, the PC55MR-5 provides greater stability when working on slopes or uneven ground while maintaining maximum digging performance. The excavator weighs in at 5,268 pounds with rubber tracks and 5,235 pounds with steel tracks — up to 625 pounds lighter than the previous model. This is a major advantage when transporting the machine over long distances between jobsites.

In addition to a more powerful engine, the PC55MR-5 has a number of other improvements that help contractors reduce operating costs. Specifically:

Improved fuel efficiency due to load sensing hydraulics, which minimizes pump flow when maximum.

According to the company, the excavators are designed to be easy to transport and service. The machines have a narrow stance and the width of their tracks can be narrowed to make them suitable for transport on public roads.

They’re also equipped with an automatic deceleration system known as Auto Decel Control (ADC), which is intended to reduce fuel consumption by automatically returning the engine speed to idle when it detects that the machine isn’t being used for a long time.

The machines also feature an auto-idle system that returns engine speed to idle whenever the operator takes their foot off the accelerator pedal.

The machines feature a variable flow hydraulic system that allows multiple functions performed by different hydraulic circuits to be operated at the same time using only one engine pump, which reduces fuel consumption.

Komatsu America Corp., a leading global heavy equipment manufacturer, today introduced the new D61PXi-24 and D65PXi-24 dozers, the first dozers in a new line of intelligent Machine Control crawler dozers. The new machines are powered by an EPA Tier 4 Final Komatsu engine that provides unrivaled fuel efficiency.

“Our customers wanted more horsepower and additional features on our previous models,” said Doug Huber, senior product manager for Komatsu America. “The new PXi Series delivers on both fronts. The improved power and torque enables our customers to increase machine productivity while reducing fuel consumption. Our Intelligent Machine Control systems help operators work smarter, not harder.”

The D61PXi-24 and D65PXi-24 crawler dozers feature 181 and 190 net horsepower respectively, with operating weights of 46,816 lbs. (21 223 kg) for the D61PXi-24, and 51,980 lbs. (23 583 kg) for the D65PXi-24. Both machines provide best-in-class drawbar pull performance at 27,000 (12 158kg) for the D61PXi-24 and 30,000 lbs.

New Komatsu PC55MR-5-These mini diggers deliver exceptional performance on the job site even if they are not the biggest excavator models in their class.

Mini excavators are ideally suited to smaller jobsites. They have a limited reach, which is ideal for work in urban areas where space is tight. They are also more efficient than larger excavators when used for light-duty tasks such as trenching and landscaping.

Despite their compact dimensions, a mini excavator can be remarkably powerful and productive. The range of Cat® Mini Excavators offers the highest performance standards in the industry.

The smallest model in the range, the Cat 303.5E CR Mini Hydraulic Excavator, weighs just around 1 tonne – yet it packs a punch with its 8-kW diesel engine and hydraulic pumps that deliver a maximum digging force of 9 kN and auxiliary lifting capacity of 907 kg.

At the largest end of the spectrum, the Cat 305E2 CR Mini Hydraulic Excavator has an operating weight of 2.9 tonnes and offers incredible performance capabilities with its turbocharged 32 kW engine and bucket digging force of up to 22 kN.

New Komatsu PC55MR-5-These machines are designed to run all day with minimal maintenance.

Many industrial applications require rubber parts that can stand up to extreme conditions, with the ability to endure constant use for years, if not decades. The rubber and elastomer products used in these applications are typically manufactured using injection molding processes.

Injection molding machines are designed to run all day with minimal maintenance. The injection molding process is reliable, repeatable and fast (typically 15 to 30 seconds per cycle), making it ideal for high-volume production runs. Injection molding machines have two main components: the injection unit and the clamping unit. The purpose of the injection unit is to melt the raw polymer resin and inject it into a custom mold cavity. The clamping unit holds the two halves of the mold closed during injection, while it opens them once the part cools so they can be removed.

The primary features of an injection molding machine include:

A closed-loop system designed to ensure consistent shot size to meet quality standards

Accurate temperature control that maintains consistent viscosity of the melted plastic being injected into the mold

Energy efficiency resulting from precise control of all machine components

High repeatability and precision due to advanced machine control systems

Modern injection molding machines have many safety features including interlocks, light curtains, key switches.
