In skid-steer mode, the A220 loader can counter rotate, meaning it can basically turn 360[degrees] within its own length. In all-wheel steer, the machine has an inside turning circle of roughly 10 ft. "It''s still pretty maneuverable in all-wheel steer," said Fitzgerald. "But if you do actually need to stop and turn 90[degrees], you change it into skid-steer mode and you''re off and running."The standard machine has a maximum travel speed of 6.2 mph, while a two-speed option takes that up to 12.4 mph. Like its 863 ancestor, it packs oliver1600hydraulicpump a lot of power oliver1600hydraulicpump into a compact envelope (135.4 in. long, 82.3 in high and 74.2 in. wide), with a rated operating capacity of 2200 lb. and a tipping load is 4400 lb. Operating weight is 7745 lb. "That''s about 700 lb. more than an 863 skid-steer loader because of the added componentry," Fitzgerald said. "But it has a 2200 lb. capacity instead of the 1900 lb. that we have in the 863." Off-the-shelf CFD software is available from firms such as oliver1600hydraulicpump AEA Technology Engineering Software, a Waterloo, Ont., firm that recently introduced an updated version of oliver1600hydraulicpump its CFX-TASCflow, which features a greatly enhanced cavitation model. Cavitation oliver1600hydraulicpump is the primary cause of pump failure, Jones points out. CFD software was more geared to hydraulic flows in pumps and inducers in turbomachinery when Alfa Laval embraced the technology. The payoff has been centrifugal pumps that create less sheer and can handle some pumping jobs previously reserved for positive displacement pumps.
