Case Adds Larger Engines, Tier 4 Upgrades To Four Alpha Series Skid Steers And Compact Track Loaders

 

Upgrades to the four largest Alpha Series skid steers and compact track loaders from Case Construction Equipment, including the SR250 skid steer shown here, enable those models to meet emission requirements for Tier 4 Interim certification. Case equipped the models with cooled exhaust gas recirculation (CEGR) technology, including diesel particulate filter and diesel oxidizing catalyst.

Case Construction Equipment announced upgrades to its four largest Alpha Series skid steers and compact track loaders, which now meet emission requirements for Tier 4 Interim certification.

The Case SR250 and SV300 skid steers and TR320 and TV380 compact track loaders now feature 90-hp (67-kW), 3.4-liter Case diesel engines with the full high-pressure common rail (HPCR) design typically used in larger construction equipment. To meet Tier 4 Interim emission requirements, Case equipped the models with cooled exhaust gas recirculation (CEGR) technology, including diesel particulate filter and diesel oxidizing catalyst. Case selected CEGR technology as most appropriate for skid steers and compact track loader applications, where the engine typically runs at a high RPM.

Rated operating capacities are 2,500 lb (1135 kg) for the SR250; 3,000 lb (1361 kg) for the SV300; 3,200 lb (1451 kg) in the TR320, and 3,800 lb (1723 kg) for the TV380.

“Case skid steers and compact track loaders have always been known for power and productivity,” said Tim O’Brien, Case brand marketing manager. “Our upgraded Alpha Series models not only deliver best-in-class horsepower and industry-leading bucket breakout force – up to 8,585 pounds – but also more torque when you need it.”

He continued, “A 12-percent higher peak torque rise compared to the previous 3.2-liter engine translates into more power at 1400 rpm, while supporting faster recovery and improved reaction when the engine begins to lug.”

O’Brien noted that CEGR technology for Tier 4 is similar to that used in Tier 3, but now the fuel supply and exhaust gas recirculation process are controlled electronically to achieve greater performance and fuel efficiency, as well as even greater reliability – for example, to help protect the engine from overheating.

 

New piston design optimizes power, fuel efficiency

power and fuel efficiency.

The electronic engine controls monitor EGR sensors and other inputs to determine diesel particulate filter (DPF) system regeneration needs. As a normal course of operation, the electronic controls will trigger an automatic regeneration of the DPF system. Additionally, the system can notify the machine operator to manually regenerate the DPF system occasionally when the soot load in the DPF exceeds the range defined for automatic regeneration.

“Automatic regeneration does not cause any adverse effect on vehicle power or performance,” O’Brien explained. “The operator can continue to operate the vehicle normally during automatic regeneration.”

Controls also provide a wealth of operating data to the display panel for use by the operator and to the service tool to assist technicians.

The Alpha Series includes both radial-lift and vertical-lift models. The radial lift machines (designated with an R in the model name), are ideal for digging, prying and pushing, while the vertical lift models (designated with a V), excel on lift-and-carry applications.

Designed for operator comfort

The new engine delivers lower noise and vibration to keep the operators more comfortable and productive, all day long.

Electro-hydraulic (EH) controls with switchable patterns are available on all Alpha Series models. This is especially helpful when two or more operators run the same machine. Operators can easily switch between control patterns based on preference.

Exceptional visibility, operator comfort, climate management and operator controls define the Case Alpha Series machines. The skid steer cabs, which are the widest in the industry, feature ultra-narrow wire side screens that improve operator visibility. Extra glass surface gives the operator 360-degree visibility.

The Alpha Series cabs also provide a superior climate management system. The sealed, pressurized cab significantly reduces the amount of noise and dust.

 

Dozer-style undercarriage

As in previous Case models, the upgraded Case TR320 and TV380 compact track loaders feature a dozer-style undercarriage, engineered to hold fast on steep slopes and take command of muddy or sandy terrain.

The undercarriage has a rigid track frame with fewer moving parts, so it is more durable and easier to maintain than suspension track systems.

Easy maintenance  

Easy access to filters and engine fluids makes maintenance on the Case Alpha Series models a breeze. The regular maintenance points are grouped in one area so operators do not need to walk around the machine to find specific service points.

Maintenance points, such as the radiator, fuel filter, battery terminals and engine oil fill are easy to find under the engine compartment cover and door. A removable side panel provides access to the engine oil filter and environmentally friendly drain. Additionally, the oil cooler and radiator tilt out for easy cleaning.

O’Brien noted the importance of using ultra low sulfur diesel fuel with HPCR engines.

Fuel systems in the upgraded Case Alpha Series models include primary filtration of impurities down to 10 microns, and secondary filtration to 3 microns. Change intervals for both filters are at 500 hours.

12 Things To Consider When Selecting A Machine For A Job

By Greg Sitek

Load a truck, cut a trench, break pavement, drill a post hole, plant a tree, lay cable, dig a swimming pool, landscaping, pipe laying, rough grading are only a few of the things you can do with a backhoe loader or a compact excavator.

It’s not about the machine; it’s about the tool doing the job. A trench is trench and will never know, understand or care about how it came into existence. A tree doesn’t care about how it got planted; paths aren’t the least bit concerned on what was used to grade and create them.

You’re a contractor and you’re getting ready to bid a job. The first question is: what needs to be done:  It’s a mass excavation project that involves moving 2.5 million cubic yards of material? You’re not going to do this wit a backhoe loader or compact excavator, that’s for certain. How about a landscaping job that includes a pond, irrigation system, some paths, a little re-contouring of the terrain, drainage tiles, shrubs, trees and lawn?

The next question is: what do I have in my equipment fleet I can use to do this job? There are any numbers of machine combinations that you could use to get the project done. Or, there is one machine with a combination of attachments that could do the job, minus long distance hauling.

If you had a compact excavator(s) and wheel loader(s) with the right attachments you could use them or if you had a backhoe loader, with the right attachments, you could use it.

Deciding which combination will work best should be based on an analysis of a number of factors. If you’ve been in the business for a while, you probably do this already. Some people call it “seat-of-the-pants guesstimating.” I’ve learned over the years that sometimes the intuitive, gut feeling is just as good because subconsciously you really do go through a process of making the decision.

Let’s take the time to do the mental gymnastics. I’m sue there are computer programs around that you can feed the information into that will guide you the best answer based on your circumstances.

Time: How long will it take you to complete the project with the excavator/wheel loader combination? How long will it take to complete the project with the backhoe loader? Machine size will be a determining factor but so will the application. If you use the excavator and wheel loader will you use two operators or one moving back and forth between the two machines? If the project is such that it can be done with two operators running two machines this will cut down on the time spent. The backhoe loader can only perform one function.

Transport: Getting the equipment to the jobsite is a consideration. Can a single trailer handle the excavator and wheel loader along with the attachments in a single trip? Running back and forth to the shop is both time and fuel consuming. There was a time, not that any of you would remember it, when fuel costs were not the number one operating cost for a piece of equipment.

Fuel: If you’re keeping records you should know what your fuel consumption rates are on each machine. If you’re really concerned about fuel consumption, and you should be, you will know the difference an operator makes on a machine. At a recent press conference Volvo Construction Equipment was talking about a program a training program it has developed.

The operator – making the (right kind of) difference

Volvo Eco Operator program is a good example of training that gives operators the practical and theoretical knowledge they need to become safer, more efficient and environmentally conscious while operating equipment. The program teaches operators correct machine operation and maneuvering as well as how to plan their work in the smartest, most efficient way. By following these techniques, operators can help save money on fuel, increase overall production and reduce maintenance expenses.

Eco Operator consists of classroom theoretical training and practical, hands-on experience.  The content can be customized with additional modules such as environmental training, simulator based training and on site follow-up. For the operation portion, a trainer sits with the operator in his own machine on an actual jobsite. The trainer gives guidance on how to change behavior in order to operate more fuel efficiently. This not only helps operators learn on a machine they’re already familiar with, but the training course does not disturb the normal operations of a jobsite – so workers stay productive.

Major contractor Skanska was one of the companies to enroll its operators in a similar scheme. In one study where 37 operators were given training, it was found that fuel consumption reduced by 5 % – representing savings of over $320,000 and a reduction in emissions of 500 tonnes of carbon dioxide. Some operators reduced their consumption by 25%.

Fuel consumption rates will be different on the different machines and in the hands of different operators. In today’s economy fuel consumption has to be given serious consideration. It does have an impact on the bottom line.

Maintenance: Maintenance requirements will vary depending on the number, size and type of machines being used. Is it easier and more economical to take care of one machine? Or two? Your records are the best source for the answer. Typically the greater number of machines on the job the greater potential for problemsAnother consideration is maintenance consumables – filters, lubricants, hoses, belts, etc., especially if you’re going to do routine maintenance at the jobsite.

Operators: If you’re planning on operating both machines simultaneously then you will need two operators. Will the timesavings and production benefits outweigh the costs of an additional operator? Are there additional benefits to having more than one operator on the job? When you think about the operator(s) don’t forget all the “fringe” costs that are associated with having employees.

Insurance: Insurance premiums need to be considered, not only on the equipment by for the employees as well.

Wear: Which approach will result in the least amount of wear on the equipment and the attachments?

Attachments: Another consideration is attachments. Ask yourself if you could improve productivity, fuel consumption, and total efficiency with different attachments. There are hundreds of them available for all these machines: backhoe loaders, compact excavators, compact wheel loaders. In fact today’s versions of these machines are designed specifically to accommodate attachments. Several manufacturers make “tool carrier” models of their backhoe loaders featuring quick couples on either or both ends of the machine. Compact excavators and wheel loaders have always been know for their versatility through the use of attachments.

In addition to the attachments made by the specific machine manufacturer there are other manufacturers that specialize in the design and development of attachments. When you’re looking for enhancing your performance with attachments, Doug Amerman, Director of Marketing and Business Development for Paladin Construction Group advises, “make your attachment purchase easier by knowing these simple things beforehand:

 

  • Application: Know your material density and/or job requirements. If possible, bring a small sample to the dealership. It’s also important to know how you will be using the attachment. For example, do you need to work at specific heights or angles?
  • Cycle Time: Know the required speed to get the task done on time and the estimated amount of travel needed to get around the job site with the attachment.
  • General Machine Specs: Know the equipment model numbers, tip load, lift/weight capacities and any other basic information for all machines the attachment will be working with. In addition, know the non-standard features on each machine (e.g., changes to hydraulics, tires, engine, etc.).
  • Hydraulic Capabilities: If your attachment requires hydraulics, make sure you know your machine’s hydraulic flow (gpm) and pressure (psi) output capabilities. In addition, make sure you understand your hydraulic plumbing, the number of outlets and its function capabilities. Not all machines have a 3rd or 4th hydraulic function capability and yet a lot of attachments require these.
  • Mounting Ability: Dealers may assume you have a universal coupler, especially for skid steers and compact wheel loaders. If you have a quick coupler, know the brand and model, and bring the serial number of the coupler if available. When possible, bring a photo.”

Beware Of Manufacturer Shortcomings…

Quality and reputation are always important. You know that…but people often don’t dig deep enough or ask the right questions about the brand being purchased. Sometimes thinking ahead about what you might need in the future can save a lot of headache. Some questions to ask your dealer include:

  1. Have you seen this brand of attachment succeed or fail in other customer applications? If so, what applications?
  2. What repair capability do you have on this attachment and do you stock all replacement parts? If you don’t carry the parts, how quickly can you get them?
  3. Does the manufacturer of this attachment specialize in this application or is this just something they produce or outsource to complete their product line? Is this attachment and/or application one where they have a proven reputation for quality?
  4. What would you estimate is the overall cost of ownership of this attachment?

Rent:  When you’re done running this information through your cranium computer, reconsider everything using larger, faster, more productive equipment. Then ask yourself if you would be economically ahead renting “bigger” or more equipment. Sometime we think that using what we have is the best way to go when it may not be the wisest economic choice. The bottom line has to be the approach that puts the highest percentage of profit in your pocket.
