GRADALL® XL 5200 III CRAWLER EXCAVATOR
ON DISPLAY AT BAUMA 2010

The world's largest and most important trade fair for the construction and mining industries takes place April 19-25 at the New Munich Trade Fair Centre in Munich, Germany. Held every three years, the last Bauma show in 2007 attracted 3,002 exhibitors - including Gradall - representing 49 countries. The 2007 show covered 5.8 million square feet and attracted more than 500,000 visitors from 19 countries.

The Gradall XL 5200 III crawler excavator, weighing 54,452 pounds (24,699 kg), is the largest model in the Gradall fleet of machines designed for highway construction, high productivity excavation, demolition and material movement as well as finished grading and sloping.

The machine features the highly productive telescoping tilting boom, which requires only minimal overhead clearance that allows it to work in tunnels, under bridges, on the ground floors of multi-story buildings and other places where conventional excavators with knuckle booms simply will not fit.

Another unique advantage is the ability of the entire boom to tilt 220 degrees for perfect attachment positioning without losing boom power. In order to perform a tilting action, conventional excavators must add a boom-end tilting mechanism, which adds weight and sacrifices boom forces.

The XL 5200 III has excellent boom force at 24,941 pounds (111 kN) and bucket breakout force at 25,405 pounds (113 kN). That exceptional power complements the boom movement advantages to make the machine ideal for a wide range of jobs working on the toughest terrain.

When switching from high production to finishing work, the load-sensing high-pressure hydraulics system adjusts automatically to save fuel and eliminate the need for operating mode selection.

The all-weather operator cab is roomy and comfortable, with rubber mounts that limit shock and vibration when the machine is digging. The seating module can be adjusted eight different ways, while the left and right arm pods contain electronic joysticks that control the 220 degree tilt and other boom functions.

The XL 5200 III boom can telescope to 33 feet, 11 inches (10.3 m) at ground line, or dig to a depth of 25 feet, 4 inches (7.7 m). Using a new in-cab switch, the operator can quickly select the Gradall, Deere or SAE joystick pattern - a feature that can shorten the learning curve for new operators. Operators also appreciate standard air conditioning, heater, acoustic lining and a removable overhead skylight and removable front window for fresh air.

Easy-to-see gauges monitor critical machine functions including engine RPM, oil pressure, battery voltage, hydraulic oil and coolant temperatures.  Some other handy controls include a dig mode switch for fine grading control or maximum performance digging and a joystick lock for safe travel during transport.

A new counterweight design shortens the rear swing of the XL 5200 III allowing it to work on road demolition and grading with only minimal traffic obstruction. Attachments include trenching, excavating, ditching, pavement removal and dredging buckets. Also available to expand the versatility of the XL 5200 III, is a grading blade, boom extensions, tree limb shear, live boom and fixed thumb grapple. Because it can do so many different jobs, the XL 5200 III often relieves the need to bring extra machines to a job site.

The long crawler track provides a solid work platform and creates minimal bearing pressure.  Triple Grauser excavator pads, with widths of 800 mm or 600 mm, assure mobility in sticky mud, sand and very rough terrain. Each track has dual range high torque piston motors. A three-stage planetary drive and automatic swing set wet disc parking brake provides sure travel and stopping capability.

To control crawler speed and direction, the operator has two electronic foot pedals with handles in the cab offering individual track control. An automatic two-speed control can shift the crawler into low speed for challenging travel conditions. Also, the operator can manually switch from high speed to low speed when loading the machine for transport.

Routine maintenance and adjustments are simplified. For example, track tension is easily controlled with an adjustment cylinder. A recoil spring on each crawler idler keeps rocks and debris from breaking or jamming the track rail, and sealed rollers feature lifetime lubrication. For excellent strength to withstand shocks, the carrier frame is a one-piece weldment. The rigged triangular boom has double rollers and provides excellent protection for the boom tilt motor, located at the rear of the boom. A single Detroit Diesel 173 horsepower engine powers the carrier boom and the load-sensing, axial piston hydraulic pump. A fuel tank carrying 99 gallons (375 liters) is larger than most other excavators, typically eliminating the need to stop work for re-fueling during the day. A rugged one-piece undercarriage weldment provides excellent strength to the carrier.

The XL 5200 III shares most service parts and attachments with other Series III models, reducing inventory requirements. By design, most service points can be reached at ground level.
