Dressta 555C Extra
The newest addition to the Dressta lineup is the 555C Extra wheel loader, featuring a new turbocharged, in-line six-cylinder Cummins QSM11 engine. This 10.8-litre, Tier 3 certified engine delivers 319 net horsepower (238 kW) at 2,100 rpm, or 330 net horsepower (247 kW) with minimum fan usage. Maximum torque is 1,235 lb-ft (1674 Nm) at 1,400 rpm. This 6.5-cubic-yard-size wheel loader can be equipped with buckets ranging from 5.5 to 11.0 cubic yards (4.2 to 8.4 cubic metres) and has an approximate operating weight of 66,380 pounds (30,110 kg). Dressta has added a new cooling module and upgraded the hydraulics system to allow for a variable speed fan that provides greater cooling and potentially more horsepower. The battery has been moved to the rear of the machine above the steps for easier access. The 555C Extra features an electrically controlled, full-power-shift, four-speed countershaft transmission driven by a double universal joint from the torque converter. This provides proper ground speed match for alloperations. Other major features of the 555C Extra include hydrostatic steering, single lever hydraulic controls, and internal wet disc brakes. The “picture window” cab offers exceptional visibility in all directions.
