A New Generation of Bobcat Loaders
West Fargo, ND ? January 2006From the inception of the skid-steer loader nearly 50 years ago, Bobcat Company has changed as times have changed by incorporating innovative technological advancements to improve its compact equipment. That tradition is continuing with the introduction of K-Series skid-steer loaders (S130 through S300), compact track loaders (T140 through T300), and the A300 all-wheel steer loader. Bobcat Company is a business of Ingersoll-Rand Company Limited, a diversified industrial firm.
New to the K-Series loaders is the SmartFAN cooling system, a hydraulically driven cooling fan that senses machine operating temperatures and then self-regulates to rotate only as fast as it needs to. The temperature-controlled, variable-speed fan optimizes the cooling needs of the loader and can be 30 percent quieter in some operating conditions. A quieter machine reduces operator noise fatigue, allows for better communication with others outside the cab, and enables contractors to work longer days by complying with city noise ordinances. For even better sound reduction, customers can purchase an optional sound reduction package.
The K-Series loaders continue to feature the exclusive Bobcat dual-path cooling system, which brings in cool, clean air from above through the oil cooler and radiator and pulls hot air from the engine and hydrostatic area exiting out two side vents. This design reduces dirt and debris restrictions in the cooling system and minimizes debris in the engine compartment.
Though Bobcat loaders are already regarded as having the best chaincase designs in the industry, Bobcat upgraded the drive chains size to 120 HSOC (high strength oval chain) from 100 HSOC on K-Series large-frame loaders. This upgrade makes the bowtie-style drive chains 38 percent stronger, thus extending their service life in tough applications such as those requiring over-the-tire steel tracks or solid, poly-filled, or segmented tires. The Bobcat chaincase is virtually maintenance-free because no chain adjustment is needed and its protected axle seals and bearings never need greasing.
K-Series large-frame vertical lift path loaders also received an extra lift. By adding an extra 2 inches to the loaders' lift height, operators will be able to load and unload materials from trucks more easily. The K-Series large-frame loaders with vertical lift path include the S250, S300, T300, and A300.
By adding the K-Force hydraulic system to K-Series medium-frame loaders (S130 through S205 and T140 through T190), operators can get the same technology and hydraulic performance already available on large-frame loaders. The new hydraulic system features a dedicated charge pump that provides an 8 percent increase in hydraulic breakout forces, hydraulic lift to full height, and attachment torque. The system produces more usable hydraulic horsepower that allows more efficient operation of ground-engaging attachments, thus reducing the chances of stalling or having to reposition.
An innovative improvement made to K-Series compact track loaders (T180 through T300) was the addition of another roller to their track undercarriage. The additional roller provides better ride quality and improves roller life and overall track life.
