The Gradall XL 4100 III excavator has a single Detroit Diesel Mercedes engine, providing an extra edge in horsepower while cost-efficiently operating both the over-the-highway carrier and the powerful upperstructure and boom. The ability of the operator to drive the excavator to job sites and then back to the safety of the equipment yard at night saves time and eliminates the need for a trailer — a traditional advantage for Gradall’s highway-speed models.
The XL 4100 III carrier tail swing is 12 in. (30.5 cm) shorter than the XL 4100 II, the model it replaces in the Gradall lineup. The shorter tail swing allows the machine to be more productive on roadside jobs, with less interference with traffic. The carrier is available in either 6 x 4, weighing approximately 47,500 lbs. (21,545 kg) and 6 x 6, weighing approximately 49,420 lbs. (22,416 kg).
The spacious upperstructure cab has more standard comfort features and operating advantages including a switch that allows the operator to select the Gradall, Deere or SAE joystick pattern — a feature that shortens the learning curve for some equipment operators. Another cab switch adjusts carrier speed during repositioning from the upper cab.
The advanced hydraulics system has pressure-compensated, load-sensing valves with circuit reliefs on all circuits. This system delivers the right amount of hydraulic power to the boom, increasing cost efficiency when performing a wide range of jobs from high productivity excavation to loading trucks or even spreading soil and grading. Rated bucket force is 24,900 lbs. (111 kN) while the telescoping boom crowd force is 24,500 lbs. (109 kN). Unlike conventional excavators, the telescoping boom forces are constant through the entire dig cycle, according to the manufacturer.
The automatic hydraulic system allows operators to concentrate on the joystick controls, built into the large seating module armrests, to mange boom motions that telescope, tilt 220 degrees, swing from side to side or up and down. The low profile telescoping boom action allows the XL 4100 III to work where conventional knuckle booms cannot, under bridges and tree limbs or in tunnels.
The boom delivers a maximum reach of 30 ft. 3 in. (9.22 m) at grade; a dig depth of 20 ft. 3 in. (6.17 m); and a lift height of 22 ft. 6 in. (6.83 m).
Increased swing speed and cycle times, combined with the power of high pressure hydraulics, make the XL 4100 III competitive with conventional excavators while also handling the work of many machines. To achieve full versatility, a single operator can quickly change between an array of attachments including excavating, trenching, ditching, pavement removal and dredging buckets. Also available are a single-tooth ripper, grading blade, tree limb shear, grapple, and boom extensions including the Telestick. A live boom extension can give the XL 4100 III the ability to reach over obstacles and into ditches.
Like many of the component and service parts on the XL 4100 III, all of the attachments also are interchangeable with the other Gradall Series III machines. For equipment fleet owners and managers, that makes it both economical and efficient to inventory fewer service parts and attachments.
Mobility on the job site is highly efficient because the carrier can be repositioned from the upperstructure cab using foot pedals and a speed selection switch on the control panel.
Also designed for comfort as well as efficiency on highways and back roads, the carrier cab has extra sound-deadening material and an optional tilt steering wheel. The carrier has a 9-speed transmission and clutch with hydraulic actuation and double plate. Other standard features include hub piloted disc wheels, upper cab wiper and washer, rear tow hooks and an air ride seat in the carrier.
Maintenance advantages include an internal swing gear, planetary tilt transmission that’s “lubed for life” and the elimination of boom tilt rollers to avoid service time for roller lubrication and adjustment. The new diesel engine allows for longer periods between oil and filter changes, fuel filter and coolant replacement and valve adjustments. Most service points can be reached at ground level to help assure maximum life and productivity.
