Gradall introduces major changes with XL 5100-III excavator
Gradall’s largest production model for construction markets, the new XL 5100 III, provides advantages over the model it replaces, the XL 5100. It is shorter for easier highway mobility, has a shorter rear swing and weighs just over 55,000 pounds. 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.
While the old model requires two fuel tanks – one with 86 gallons and one with 50 gallons – the efficient new engine is paired with a single 100-gallon tank. Also, the new engine has a longer warranty with standard 600-hour service intervals rather than the 250-hour intervals required by the engines it replaces.
Within 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 that set the industry standard in construction equipment versatility. 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, painted in the new Gradall colour scheme – gray with red trim and dark gray cabs – similar to the XL 3000 and XL 4000 models. But the XL 5100 III carriers are 6 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 6 inches. The shorter swing clearance enables the machines to deliver greater performance in tighter quarters, reducing interference with moving traffic during highway demolition and repair work.
The new upperstructure cab is located on the left side of the machine, a familiar location for operators of Gradall XL 4100 and XL 3100 highway speed models.
The upperstructure swing speed has been increased by 33 percent, providing greater productivity for truck loading and unloading, allowing the Gradall to compare favourably 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 either the Gradall, SAE or Deere joystick pattern.
