Dressta North America, Buffalo Grove, Ill., has introduced the 55c Extra wheel loader, featuring a new turbocharged, in-line six-cylinder Cummins QSM11 engine. This 10.8 liter Tier 3 engine delivers 319 net horsepower at 2,100 rpm or 330 net horsepower with minimum fan usage. Maximum torque is 1,235 pounds per foot (lb-ft) at 1,400 rpm. This 6.5-cubic-yard wheel loader can come equipped with buckets ranging from 5.5 cubic yards to 11.0 cubic yards and has an approximate operating weight of up to 66,380 pounds. Dressta has added a new cooling module and upgraded the hydraulics system to allow for a variable speed fan, which is designed to provide greater cooling and potentially more power. The battery has been moved to the rear of the machine above the steps for easier access. The 555C Extra features an electronically controlled, full-power shift, four-speed countershaft transmission driven by a double universal joint from the torque converter. Other features include hydrostatic steering, single-lever hydraulic controls and internal wet disc brakes.
