Case Construction Equipment introduced its Tier 4 Final skid-steer loaders last week at The Rental Show in Las Vegas. The four new models are upgrades to its Alpha Series line. The Case SR175 and SV185 medium-frame skid steers meet the mandate with new engine technology and a diesel oxidation catalyst (DOC) solution only. The SR130 and new SR160 compact frame skid steers meet Tier 4 Final status using the more typical cooled exhaust gas recirculation (CEGR) with diesel particulate filter (DPF). Additionally, the large frame SR220 and SV250 skid steers move to Tier 4 Interim with CEGR and DPF technology.
The SR175 and SV185 skid steers are updated with a new ISM diesel four-cylinder turbocharged and after-cooled engine with a high pressure common rail (HPCR) fuel system design and electronic controls. According to Tim O’Brien, brand marketing manager for Case Construction Equipment, the company designed these machines with a DOC-only solution because it was the best match for customers who use this size skid steer.
"From the beginning, our goal for the Tier 4 industry emissions mandate has been to go beyond compliance and do what’s in the best interest of our customers,” said O’Brien. “The SR175 and SV185 skid steers commonly are used in fleets and the rental market, and subsequently a machine may have many operators and move around a lot. Therefore, the maintenance-free DOC-only solution made the most sense for these models because it’s more convenient and efficient than using CEGR with DPF, or even selective catalytic reduction with diesel exhaust fluid to meet emissions.”
The SR175 and SV185 sister machines, designed for radial-path lift and vertical-path lifting, respectively, both offer even greater torque power. The SR175 has a 21-percent higher peak torque rise at 1,800 rpm compared to the previous model, and goes from 60 to 67 gross hp, a 12-percent increase. While the SV185 remains at 60 gross hp, it has 7-percent more torque than the previous version.
The SR130 skid steer remains a good utility model with a high level of features and productivity in a small package. The newest version features a 2.2-liter ISM engine and moves from 46 to 49 gross hp. It also receives a 9.6-percent torque boost while maintaining its same dimensions.
The SR160 is an evolution of the SR150 skid steer and delivers 7-percent more rated operating capacity and 17-percent more horsepower than the SR150. It has a 10-percent larger engine than the SR150 and a turbocharger to deliver 60 gross horsepower and a 28-percent torque increase.
The larger SR220 and SV250 skid steers, which now move into Tier 4 interim status, retain their 82-gross-hp engine but receive a 14.2-percent increase in torque, making them more powerful than the Tier 3 version of the larger 90-hp Case skid-steer models. Customers are able to maximize their productivity with a smaller size class machine.
“We’re really proud of these new machines,” said O’Brien. “We’re not just helping our customers meet an emissions standard — they’re also going to get more power and capability within the same compact dimensions.”
All six models now include a new electronic engine control that helps to maximize performance and ensure reliability. In addition, CAN-messaging capabilities will allow the customer to monitor and store diagnostic data points, some of which include hydraulic oil temperature, fuel rail pressure and even fuel tank level. Expanded control options are available on the SR130, SR160, SR175 and SV185, including factory-fit foot controls for the loader functions.
Case Construction Equipment sells and supports a full line of construction equipment including loader/backhoes, excavators, motor graders, wheel loaders, vibratory compaction rollers, crawler dozers, skid steers, compact track loaders and rough-terrain forklifts.
