Three new models of compact track loaders from Case Construction Equipment, part of its Alpha Series, offer rated operating capacities from 2700 to 4200 lb (1226 to 1905 kg) with a counterweight. The loaders include the 74-hp (55-kW) TR270 and the TR320 and TV380, both of which offer 90 hp (67 kW).
All three deliver a breakout force up to 8585 lb (38.2 kN) and are designed with a hinge-pin height that allows the bucket to be positioned higher, allowing the operator to load trucks faster and easier.
As in the earlier 400 Series 3 models, the new 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.
The TR270 and TR320 are both radial-lift models, while the TV380 is an all-new vertical-lift machine that Case says meets customer demand for a tracked version of its 465 skid steer. The radial lift machines (designated with an R in the model name) are engineered for digging, prying, and pushing, while the vertical lift models (designated with a V) are particularly suited for lift-and-carry applications.
In terms of benefits to the operator, the compact track loaders are said to provide improved visibility, operator comfort, climate management, and operator controls. The cabs are up to 25% larger—among the widest in the industry, according to Case. They feature what is described as an ultranarrow wire side-screen design that improves operator visibility. Also, the glass surface was increased to provide 360° visibility.
Besides being larger, Curtis Goettel, Case Marketing Manager, says the cabs "feature dozens of upgrades, including optional heated air-suspension seats, air-conditioning, a removable door, and side windows" designed to keep operators comfortable throughout the workday. The cabs also feature an improved climate management system. The sealed cab significantly reduces the amount of noise and dust. A new heating and air-conditioning system creates a comfortable environment year-round.
Case compact track loaders now offer standard two-speed travel and electrohydraulic switchable controls. “This is helpful when you have two or more people running an Alpha Series machine. Operators can easily switch to the control pattern they prefer,” Goettel said.
Coupled with improved fuel efficiency, larger 16- to 25.5-gal (60.6- to 96.5-L) fuel tanks make it possible for the compact track loaders to run for eight to 10 hours without refueling.
Easy access to filters and engine fluids simplifies maintenance on the loaders. 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 at the rear of the machine.
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.
More than 70 attachments are available, including augers, rakes, grapples, pallet forks, brooms, dozer blades, and hammers, to take on dozens of applications, including construction, landscaping, and agricultural jobs.
