Volvo Penta engine powers Gradall excavator to 60 mph
According to Gradall, the new engine improves fuel efficiency by up to 5 percent, providing power to drive the 6 x 4 or 6 x 6 models at speeds up to 60 mph. In addition, the same engine repositions the machine from the upperstructure cab at speeds up to 5 mph and powers the Gradall boom.
An advanced pressure-compensating, load-sensing hydraulic system has relief valves on all circuits, delivering the right amount of power to the boom. Without the need for selecting work modes, the system efficiently performs excavator digging, demolition and barrier placement as well as sloping, finishing, storm and canal cleanup, tree trimming and other jobs with cycle times and boom-end power comparable to conventional excavators.
Series V excavators have an upgraded high-performance, high-reliability 24-volt electrical system. An operator cab safety option provides integrated ROPS. The Gradall AutoDrive package includes a push-button automatic transmission.
XL 4100V models feature telescoping, full-tilting booms that can be equipped with a host of attachments. Maximum boom reach is 30 feet 3 inches (9.2 m) at grade, while maximum dig depth is 20 feet 3 inches (6.2 m). Loading height maximum is 17 feet 2 inches (5.2 m).
The low working profile of the boom also allows it to work in tunnels, under bridges and beneath other overhead obstructions and utilities. Rated bucket force is 24,900 pounds (111 kN) while the telescoping boom crowd force is 21,940 pounds (97.6 kN).
