Case upgrades its compact skid and track loaders to Tier 4 Final

Case Construction Equipment reports that all four of the manufacture’s 67kW compact skid steer loaders and compact track loaders now achieve Tier 4 Final compliance. Case also says that a number of detail enhancements have been made across the range of nine skid steer loaders and four tracked loaders. Selective catalytic reduction (SCR) and cooled exhaust gas recirculation solutions improve fuel efficiency, keep exhaust temperatures down, remove the need for exhaust gas recirculation and eliminate the need

Clean tailpipe emissions for Case compact construction machines
Case Construction Equipment reports that all four of the manufacture’s 67kW compact skid steer loaders and compact track loaders now achieve Tier 4 Final compliance.


176 Case also says that a number of detail enhancements have been made across the range of nine skid steer loaders and four tracked loaders. Selective catalytic reduction (SCR) and cooled exhaust gas recirculation solutions improve fuel efficiency, keep exhaust temperatures down, remove the need for exhaust gas recirculation and eliminate the need for diesel particulate filters and associated maintenance. Now this SCR-only technology is being brought to the upper end of the compact loaders’ range with the so-called Compact High-efficiency SCR, said Case.

The 67kW Compact Hi-eSCR engines, designed and manufactured by Case’s partner company FPT - 2723 Fiat Powertrain Technologies - have higher combustion efficiency. Combustion efficiency enables lower heat rejection and a reduction in the exhaust gas recirculation (EGR) rate from 25% down to 10%, the lowest on the market, according to Case.

One operational benefit of these changes is better load response, enabling the engine to react more quickly to sudden demands for increases in torque which happens often during the operation of a skid steer.

This high-performing engine has excellent torque output (383Nm at 2,500rpm) and is directly coupled to the hydraulic pumps. This means that all the power of the engine is transferred directly to the wheels.

New model numbers have been introduced. The radial lift SR270 and vertical lift SV340 skid steer loaders replace the previous top-of-the-range SR250 and SV300 models. The radial lift TR340 compact track loader replaces the TR320. The vertical lift TV380 track loader also achieves lower emissions, but because its operating capacity is unchanged it retains the same model name.  

The rated operating capacity rises from 1135kg in the SR250 to 1,225kg in the new SR270; from 1,360kg in the SV300 to 1,545kg in the new SV340; and from 1,451kg in the TR320 to 1,542kg in the new TR340.

To support the increased performance, the vertical lift models come with a stronger lift arm, as well as reinforced H-link and upper chassis.

Another real-world advantage of these upgraded models is their outstanding bucket breakout force, which ranges from 38.6kN on the SR270 up to 42.4kN on SV340.

    Smaller construction equipment offers versatile options, particularly on highway repair and maintenance projects. Patrick Smith reports. Visitors to any highway construction site across the world will see a sizeable amount of utility equipment in action carrying out a variety of tasks. Indeed, because of its smaller, more compact size, such multi-task equipment is essential when repair and maintenance projects are being carried out, particularly in urban areas where space may be limited.
