"We looked at many different ideas, including benchmarkandelectricdrilltools articulated loaders and various other concepts. What we ended up with was really two machines in one. If you have situations where you''re in very benchmarkandelectricdrilltools tight quarters and need that skid-steer function, they have that option. When you want to be out on grass or some other surface that you don''t want disturbed, you can switch into all-wheel benchmarkandelectricdrilltools steer mode. There is so much versatility, it''s like having two machines in one.And Bobcat managed to develop two machines in one while not reinventing the wheel, according to Chuck Krause, senior development benchmarkandelectricdrilltools engineer, new products group. "The basic drivetrain is the same as on our 363 loader," he said. "It has the same chain case, the same drive motors, same drive sprocket, same driven sprocket. The changes all take place on getting the power from the driven sprocket out to the axle."

In the case of RTFL, one way to address both concerns centers on the hydraulic system, the functional heart of the machine itself. A long-time global supplier to the mobile equipment industry, Parker Hannifin has developed a simple, yet effective solution called Constant Pressure Unloaded (CPU). Originally developed for the benchmarkandelectricdrilltools European market, it is also being applied in North America.CPU incorporates slight modifications made to a standard open center valve. In a standard closed center system, a piston pump or unloaded gear pump will sit at compensated pressure with functions in the neutral position. This results in a horsepower drain that is both taxing to the engine and expensive in terms of fuel consumption. Open center systems also suffer from this horsepower drain due to full flow at system pressure drops. Pressure drops as high as the system relief setting can be seen in some RTFL applications. This is not unusual in that hose lengths to and from the functions can be very long and counterbalance valves are often selected because of cost rather than flow capacity.
