Gradall’s new XL 5100 III excavator now uses just one engine and is narrower for highway travel
Gradall has introduced the XL 5100 III excavator – the company’s largest production model for construction markets. It weighs just over 55,000 pounds and represents dramatic new Gradall-engineered advantages over the model it replaces, the XL 5100.
Unlike the XL 5100 that used two Cummins engines, the XL 5100 III uses just one Detroit Diesel Mercedes engine. Conserving fuel while producing greater horsepower, the new engine operates both the truck carrier and the upperstructure and boom. Plus, the concept reduces maintenance costs with only one electrical system, one radiator, one set of filters and other non-redundant features.
From the chassis cab, the operator can drive the excavator at highway speeds to one or more job sites in a single day. And from the upperstructure cab, the operator uses the same engine to reposition the carrier and operate the powerful telescoping and tilting Gradall boom. Also, operators of the new model have greater control over their carrier positioning speed using a two-speed switch in the upper cab.
XL 5100 III models are available in 6 x 4 and 6 x 6 configurations. The XL 5100 III carriers are six inches narrower than the models they replace, so they now can be driven on highways without an over-width permit.
A newly designed counterweight is higher, without restricting operator vision, and more compact, helping to reduce the swing clearance by 18 inches and the total length of the undercarriage by six inches. The upperstructure swing speed has been increased by 33 percent, providing greater productivity for truck loading and unloading, allowing the Gradall to compare favorably with high performance conventional excavators. Bucket breakout force is increased from 21,900 to 24,900 pounds and boom crowd force increases from 23,390 to 24,500 pounds.
New electronic joysticks replace hydraulic controls, providing optimum reliability. Also, using a switch in the cab, the operator can now select the Gradall, SAE or Deere joystick pattern. Another convenient switch for the operator sets carrier speed during repositioning from the upper cab.
The boom movement hydraulics system uses a single load-sensing axial piston pump – an efficient load-sensing design that automatically adjusts boom power for high productivity excavating, ditching, loading and demolition or standard grading, sloping and finishing. Not only is the load-sensing feature convenient and productive, it also allows for fuel savings. Operators of the new model also have the option of reducing engine rpm from 1,900 to 1,700 using a new switch in the cab.
The Gradall boom benefits from a telescoping action that allows it to work under bridges, trees, signage, top down excavations and on the ground floors of many multi-story construction projects. Also unlike conventional booms, the telescoping action delivers consistent power throughout the entire digging cycle.
Gradall offers buckets designed for excavating, pavement removal, dredging, ditching and trenching. Also available are grapples, hammers, grading blades, Telestick and standard boom extensions, a tree limb shear and a live boom that can reach over obstacles and dig straight down. Attachments are interchangeable with Gradall XL 4100 II models.
The XL 5100 III carrier is armed with an Eaton Roadranger transmission with nine speeds forward and two reverse. Operation is much quieter thanks to a series of advantages like a variable viscous fan clutch system, while the new chassis benefits from a stronger new axle, standard low profile radial tires and hub piloted disk wheels.
