Dressta has enhanced the top end of its wheel loader line with the new 560E Extra, featuring a high performance Tier III engine, joystick boom and bucket controls, hydrostatic steering, and a high visibility cab. It has a payload capacity of 7 to 15 cu. yds. (5.35 to 11.5 cu m) to go along with a 92,549-lb. (41,980 kg) operating weight.
Power for the Big Loads
The new turbocharged in-line six-cylinder Cummins QSX-15 engine increases power from 415 to 427 net hp (310 to 319 kW). A variable speed cooling fan allows the engine to provide 445 hp (332 kW) at minimum fan speed. The oil change interval has been extended to 500 hours. The 6,390-lb. (2,900 kg) counterweight, previously optional equipment, is now standard.
Combined with a three-speed, full power shift, countershaft transmission, torque converter, front and rear drive axles, and conventional differentials, the 560E Extra delivers reliable and durable power transfer for high production even in slippery conditions.
“We designed the Dressta 560E Extra to deliver the extras customers look for in a big wheel loader,” said Tom McGonigle, director Dressta North America. “You get big machine comfort and power with fast cycle times and low cost of ownership.”
With the power shift, countershaft transmission on the 560E Extra, the operator experiences smooth modulation on all shifts, providing a more comfortable ride, according to the manufacturer.
The countershaft transmission allows the gears to constantly mesh to virtually eliminate adjustments and the design requires a minimum number of parts for service and repair, providing long term, trouble free operation and lower cost of ownership.
Z-Bar Linkage for Maximum Breakout Force
The Dressta 560E features a Z-bar linkage that transfers maximum breakout force to the bucket to pry out hard packed material. The design features a single bucket cylinder that puts less weight on the front. It also keeps the number of components and wear and maintenance points to a minimum for long life and easy maintenance. All loader linkage pins are sealed to keep out abrasive dust and grit.
The design extends lubrication intervals as well as pin-bushing life, boom cylinders are mounted outside the front frame for easy access and maintenance and the hydraulics on the Dressta 560E Extra provide improved cycle times.
Four wheel, hydraulic, multiple wet-disc brakes (C-Series) are completely sealed and force cooled to reduce downtime and improve reliability and safety.
The 560E Extra is easy to operate with directional transmission and speed shifts controlled by two levers at the operator’s fingertips. This machine features an articulated frame with a tight turning radius of only 26 ft. 4 in (8.03 m).
Hydrostatic steering provides smooth control at any engine speed. A full complement of gauges and warning lights keep the operator on top of operating conditions and the cab offers high visibility in all directions. The 560E Extra is part of the complete Dressta wheel loader line that also includes the 515G, 520G, 530E, and 555C.
