Case Construction Equipment has announced it has enhanced the capabilities of four of its skid steer loaders, making them the most powerful and largest radial-lift products in its history.
The improvements mean that as well as having increased operating capacity, all four of the 90hp compact loaders are now Tier 4 Final compliant and new model numbers have been introduced to reflect these changes.
The previous top-of-the-range radial lift SR250 and vertical lift SV300 models have been replaced by the SR270 and SV340 respectively, while the TR340 compact track loader supersedes the TR320. The vertical lift TV380 now also achieves lower emissions, but due to an unchanged operating capacity, retains its model name.
Compared with the original models, the operating capacity of the SR270 has increased to 1,225kg, the SV340 to 1,545kg and to 1,542kg for the TR340.
New engine architecture
Being the first construction OEM to offer both selective catalytic reduction (SCR) and cooled exhaust gas recirculation to support reaching the stringent emissions standards, Case is also introducing this effective solution to the higher end of its compact loader range of vehicles. Keeping exhaust temperatures down, SCR removes the need for exhaust gas recirculation and eliminates the need for diesel particulate filters which require additional maintenance attention.
Designed and manufactured by the supplier Fiat Powertrain Technologies, the new so-called 90hp Compact Hi-eSCR engines powering these four skid steer loaders provide improved combustion efficiency to enable EGR rates to be cut from 25% to 10%. In addition, the engines provide 383Nm of torque at 2,500rpm.
“The combustion efficiency of 10% is the lowest on the market,” said a Case spokesman, adding “but these high-performing engines also provide excellent torque output and are directly coupled to the hydraulic pumps, which means that all the power of the engine is transferred directly to the wheels.”
