Case Construction Equipment Case Construction Equipment

A Baker’s Dozen of Powerful, Tier 4-Compliant Machines

Case Construction Equipment is built on a foundation of innovation that dates back to the first threshing machines Jerome Increase Case (AEM Hall of Fame, 2008) built in 1842. The need for more advanced road construction equipment grew as the United States and the rest of the world became more modernized, and Case responded with powerful engine-driven equipment, including hydraulic excavators. Case excavators have evolved over the years, while retaining many of the same core principles with each generation: strong hydraulic power, excellent controls and cab environment and greater fuel efficiency with each generation — all while meeting stringent Tier 4 emissions standards.

Case offers 13 mid- and full-size excavators ranging from 16,200 lbs (the CX75C SR) up to 178,575 lbs (the CX800B), with a combination of conventional, long reach and minimum swing radius designs. Each Case excavator is engineered to provide an optimal combination of speed, power, operator comfort, control, reliability and support. One of the hallmarks of Case excavators is the Case Intelligent Hydraulic System (CIHS). The CIHS relies on four integrated control systems to make the best use of the machine’s hydraulic power and momentum. This helps these excavators exert only the power and force required for the task at hand, while also improving important performance metrics such as increased lifting power and faster cycle times. The first of Case’s Tier 4 Final D Series excavators will be available in North America later in Q1 2015 and will replace a number of the current C Series models.

Product Spotlight: CX350D
The new Case CX350D (available Q1 2015) offers significant advances in power, fuel savings, operation and control — all while meeting the new Tier 4 Final regulations for emissions control. The Case CX350D features an innovative combination of cooled exhaust gas recirculation (CEGR), selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) technologies with no DPF and no DPF regeneration, which helps maximize uptime, performance and profits.

This system, in coordination with advances in hydraulic control and function, provides contractors added power and performance while running more efficiently. This includes cycle times up to 12 percent faster, improved lift capacity, up to 8 percent greater fuel efficiency, up to 6 percent greater breakout force and improved responsiveness and multifunctional control (simultaneous operation of boom while swinging, etc.) — all made possible by the advances to the Case Intelligent Hydraulics System and other systems throughout the machine.

Advice
“Never underestimate the power of hydraulics, electronics and other supporting systems throughout the machine,” says Philippe Bisson, Brand Marketing Manager for Case Construction Equipment. “Much of what’s being marketed right now revolves around Tier 4 technology. That’s critical, but it’s some of the other primary systems that achieve efficiencies and productivity gains. Hydraulics play a big part in maximizing the energy generated by the machine and distributing it throughout the boom and the rest of the machine to perform its work as efficiently as possible. And electronics enable many of the control settings/modes that really dial these machines in — take these features into consideration as well.”

The new 190G W and 230G W wheeled excavators bring added mobility and maneuverability to the jobsite. Both models feature a 159-hp certified Tier 4 Interim Isuzu engine. This quiet, durable and reliable engine is mated to the John Deere Powerwise III hydraulic engine management system that offers three productivity modes: High Productivity, Power and Economy mode, as well as a Power Dig and Auto Power Lift function. High productivity mode delivers more power and faster hydraulic response to move a greater amount of material. Power mode delivers smooth and balanced metering for normal operation, and Economy mode reduces top speed and helps save fuel. For convenience, the Power Dig button allows an operator to get the extra hydraulic power to increase productivity.

Contractors can choose from a variety of boom, blade, outrigger and bucket options to equip their excavator exactly as needed to optimize setup. The G-Series short wheelbase makes them very adept in close quarters — unlike truck-mounted excavators. For work close-up, operators can opt for the two-piece boom. Contractors looking to get the most out of their John Deere excavators can rely on Ultimate Uptime featuring John Deere WorkSight. With Ultimate Uptime, operators receive pre-delivery and follow-up inspections, three years of JD Link telematics and much more.

Advice
“When looking at excavators, consider cabs with more legroom, adjustable seats and a wider range of visibility that can help make long days on the job less cumbersome,” says Mark Wall, Excavator Product Marketing Manager. “Technology upgrades like LCD monitors, navigation systems and monitoring tools provide an interactive user interface. With the right upgrades, operating an excavator isn’t much different, amenities and comfort-wise, than driving your car. Be sure to test or demo the unit on the jobsite as well. Get a real-time feel as how the machine will be used.”


Caterpillar  Caterpillar

Solid Production Meets Fuel Efficiency in 16 Hard-Working Models

In 1972, the 200 Series Caterpillar excavators were released — starting an evolution of development for the next 42 years. From the 200 Series excavators to the 300 F Series excavators, the product family has evolved to be more fuel efficient and to maintain the productivity customers have demanded from the 70s. New “hybrid” technology has been the latest development that has harnessed the power to maintain production while lowering fuel consumption. Currently, Caterpillar offers 16 models that range from 12 to 19 ton, 19 to 33 ton and 33 to 90 ton that meet the high demands of customers. The ship is moving quickly for the Caterpillar excavator family, and maintaining production has been the trend in 2013 and 2014. The company expects the major fuel consumption reductions will deliver a better return on investment for its customers.

Product Spotlight: 336E H and 335F LCR
Doing well in the 30- to 40-ton size class is the 336E H “Hybrid” model where customers have been experiencing great returns on fuel consumption in any application. The new 336F XE is the newest 36-ton hybrid where the nomenclature has now changed from “H” to “XE” as the identifier  to recognize technology going forward with the hybrid developments.

The new compact radius 335F LCR has now replaced the 328D LCR, which has improved lift and high ambient cooling with lower fuel consumption vs. the older model. The 335F LCR was the only 30-plus-ton Tier 4 Final compact radius in the market in 2014, says the company. As the 328D LCR was limited on space for high ambient cooling, the 335F LCR has enough space to handle a larger cooling package.

Advice
“When making a purchasing decision for a machine, renting can be a good resource to understand how a machine best fits your application,” says Kent Pellegrini, Product Application Specialist for Cat. “This will enable you to make the purchase decision to either move up a size class or down. Depending if the machine will be a primary digger or lifter is up to the job requirements. Having a machine that can stretch up to another size class in lift can be a great asset and help with the transportability. If a digging machine is needed, identifying the correct truck size and pass match is critical to moving material and having the lowest cost per ton for your company. Look for the low maintenance cost and the product support that will back the machine going forward for you.”


Komatsu Komatsu

The New PC210LCi-10 Takes the Cake with Intelligent Machine Control

Komatsu entered the hydraulic excavator market in the late 1960s with the H-Series. Throughout what could be considered 11 generations, many improvements have been made such as the addition of various operating modes, short tail swing excavators, and now, the Dash 11 Series with Komatsu Tier 4 Final emissions engines. The latest Komatsu excavators provide more advanced electronic control, simplified maintenance and troubleshooting and better operator comfort. New engine and hydraulic technology has led to increased fuel savings, which can be monitored through KOMTRAX, Komatsu’s machine monitoring system. Rear-view monitoring systems are standard on most models providing improved operator visibility directly behind the machine.

Several other features are used on Komatsu’s excavators to help save fuel and improve productivity. Most Komatsu excavators use a Closed Center Load Sensing (CLSS) hydraulic system, which provides lower fuel consumption and quick response to the operator’s demands.  Most Komatsu excavators also feature an arm quick return circuit which provides faster cycle times and better fuel efficiency. Komatsu was also the first manufacturer to introduce a hybrid excavator. The HB215LC-1 is a second generation hybrid that uses an ultra-capacitor to capture energy normally lost during swing deceleration. This captured energy is then used to power the swing as well as support other functions — resulting in an up to 25 percent reduction in fuel consumption.

Product Spotlight: PC210LCi-10
The PC210LCi-10 is Komatsu’s first intelligent Machine Control excavator featuring unique machine control and guidance technologies that allow customers to unearth their productivity. New features of this model include:

Exclusive machine control function which semi-automatically limits digging below grade to minimize over-excavation and allow for accurate finish grading.

Standard factory installed 3D GNSS intelligent Machine Control system, which includes an inertial measurement unit and stroke sensing cylinders for real-time bucket edge positioning in relation to the machine and the target surface.

Minimum distance control that automatically gives guidance to the point of the bucket closest to the target surface and facing angle compass which guides an operator to swing the machine for accurate bucket positioning to finish a slope.

A large, 12.1-in. touchscreen display that is customizable can show three views at once, including 3D, as well as offering both visual and audio elevation guidance.

Advice
“It is important to understand the application the excavator will be used in,” says Rob Orlowski, Excavator Product Manager for Komatsu. “This could include working range, transportation dimensions, productivity and desired bucket selection. Bucket selection can also be dependent on the truck being loaded as well as wear packages. Reach requirements are important to make sure your machine can meet the depth requirements of the job.”

The number of switches has been significantly reduced in comparison to previous models. An 8-in. color LCD screen displaying vital machine status information is easy to read in any light.

Advice
Sejong Ko, Excavator Product Manager for Volvo Construction Equipment, suggests considering several key factors when purchasing an excavator. First, the customer should start by considering the primary job application (i.e. residential, commercial, trenching, etc.) and transportation requirements to determine the appropriate size class and type (crawler, wheeled, short swing or pipelayer). He can then choose the specific model for his needs. The second step should be to consider materials and ground conditions. Taking those into consideration, attachments can be selected, such as quick-couplers, hammers, hydraulic thumb, bucket type, etc. Additional items to keep in mind include shoe plate width and grouser type (single, double, triple and rubber), as well as boom arm lengths and counterweight size.


 

JCBJCB

Compact Design Meets Big Results in Three Steadfast Units

For decades, JCB has been producing both full-size and compact excavators. All of JCB’s weight classes of compact excavators are popular in construction applications, but as their weights increase, the machines become more popular for excavation, sewer and pipeline work.

JCB currently offers 10 different compact excavators ranging from the smallest model, the 8008, to the largest, the 86C. The range spans from 1 to 9 tons (however, the specs here only include units 6 tons and higher). According to JCB, the advantages of its compact excavators include increased visibility due to large front, side and top glass areas and a narrow boom and dipper, as well as enhanced productivity.

Product Spotlight: 67C-1, 86C-1 and 85Z-1
These three machines have launched a completely new look for JCB compact excavators, with a revised H-design undercarriage, robust steel body panels, a spacious operator environment and Tier 4 final engines that deliver increased efficiency and lower operating cost.

The 67C-1, 86C-1 and 85Z-1 are powered by all-new JCB by Kohler diesel engines, which use up to 10 percent less fuel than the previous models and conform to Tier 4 Final emissions standards without any requirement for a diesel particulate filter (DPF).

The three machines feature a sturdy swing bracket design with widely spaced bearings to prevent wear. In addition, JCB compact excavators use a new graphite-based pin-and-bush design delivering 500-hour greasing intervals for reduced daily maintenance and lower operating costs. The machines will also be available from the factory with a roto/tilt function installed, making them ready for use with a number of rotating and tilting bucket mount systems.

The JCB 67C-1, 86C-1 and 85Z-1 feature 100 percent pressed steel engine covers, delivering sturdy component protection and easy repair. The midi excavators benefit from improvements in their SAE service and maintenance rating, thanks in part to the tilting cab and repositioned components. With lower fuel consumption and no requirement for daily greasing, ownership and operating costs will be impressively reduced, says the company.

The new JCB compact excavators have a cab structure that can be tilted by 30 degrees to allow access to hoses and hydraulic components for repair and maintenance. JCB has also improved the grouping of components to reduce maintenance times. In addition, the machines have removable side skirts and in-fill panels for maximum service access, along with improved access to the cooling pack.

Advice
“Utility contractors must consider the overall return on their investment,” says Jake Jeffords, Product Specialist at JCB. “Their compact excavator must fit the operating weight, digging depth and attachment capabilities that are needed to perform everyday applications. A demo is a powerful tool to make an educated decision for your future compact excavator. While particular features can make specific jobs easier to complete, the main components of reliability, serviceability and dealer support are key to a sound buying decision.”


Terex Terex

Three Units with a Long and Proud Hanix and Schaeff Heritage

The Terex excavator line was developed and made by Hanix and distributed by Schaeff in Germany. The first model was called the HR02. Terex purchased Schaeff in January 2002. Terex compact excavators are still engineered and manufactured in Rothenburg, Germany. Through evolution of the equipment, the Terex excavator line has been more than five generations. Terex engineers have focused on bringing a machine to market that has a high power-to-weight ratio, which equals an increase in capabilities in a smaller-sized machine. According to Terex, the basic design of all Terex excavators ensures they can handle tough jobsite applications with the best performing machines in their size category.

Terex has three excavator models — the TC60, TC75 and TC125 —  ranging from 44 to 116 hp with operating weights from 12,460 to 27,560 lbs and a variety of attachments to match jobsite needs. All Terex models have two travel speeds standard. Design features, such as the company’s axial piston, variable displacement hydraulic pumps and motors provide load-sensing and load independent flow division (LUDV) hydraulics for smooth simultaneous operation. With the LUDV design, oil flow is distributed to cylinders independent of the load. The main advantage of this system is that the compact excavator can be performing multiple actions at one time, without sacrificing flow. Because the machines are engineered with productive power and smooth hydraulics, these excavators excel in tough work environments, says Terex.

Terex excavators are also engineered to provide optimal operator comfort, safety and productivity. The cabs on these machines are quiet due to the low engine noise, ergonomically designed seats, excellent visibility and ergonomically designed pilot controls ensure that the operator can comfortably sit back and operate the machine. The pilot-operated controls also provide changeable control patterns to adjust to the operator’s particular preference. Heat is standard on all models, and A/C is optional. Each unit is built with a large operator’s platform with two-sided entry for easy access from both sides of the machine.

Advice
“Selecting an excavator isn’t as simple as choosing a model with the most horsepower,” says  Jonathon Ferguson, Terex Regional Sales Manager. “The most important thing you need to know are the jobsite parameters. Then, ask yourself what is needed to complete a job from beginning to completion: Is this a typical jobsite or an exception? What will I mostly be using the machine for? How deep do I need to dig? How large are the areas I will be working in? What types of attachments do I need? All of these things need to be determined to know which compact excavator will best suit your needs.”

Advice
“One of the simplest — yet often overlooked — maintenance practices is the daily walkaround checklist,” says David Steger, Takeuchi Product Manager. “Be sure to check the engine oil, hydraulic fluid and coolant and top off when necessary. Make sure that you’re using the manufacturer-recommended fluid. Remember, it never hurts to ask your dealer or your tech. After a week or so, it is important to check the fuel filter and drain any water or debris that may have built up, or replace it if necessary. Next, check the hydraulic hoses and air system for leaks — it’s always better to find a problem and fix it while it’s small, than to wait until it’s too late. Also, remember that there are no air systems on this equipment like there might be on trucks and trailers.”
