2012, Racine, Wis. – 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.
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.
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
3.4L engine in the upgraded Alpha Series skid steers and compact track loaders
features a new, patented piston design – specifically engineered for use in
high pressure common rail (HPCR) fuel systems – that promotes thorough
combustion, optimizes power and fuel efficiency.
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.
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.
engine delivers lower noise and vibration designed for optimal operator comfortable
(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
operator comfort, climate management and operator controls define the Case
Alpha Series machines. The skid steer cabs feature ultra-narrow wire side
screens that improve operator visibility. Extra glass surface gives the
operator 360-degree visibility.
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.
undercarriage has a rigid track frame with fewer moving parts for enhanced
durability and maintenance.
access to filters and engine fluids helps to simplify maintenance on the Case
Alpha Series models. The regular maintenance points are grouped in one area so
operators do not need to walk around the machine to find specific service
points, such as the radiator, fuel filter, battery terminals and engine oil
fill are easier to find, placed 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.
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.
