With a boom that imitates the movements of the human arm and wrist, the Gradall XL 3200 is able to swing from side to side, reach up for loading and unloading as well as dig straight down. The 220-degree boom rotation allows the machine to handle delicate grading work quickly and easily, while the telescoping action maintains full power throughout the entire digging cycle. Without the need for mode selection, the hydraulic system automatically adjusts for the job at hand. The XL 3200 is equipped with a 114-hp John Deere 4045 engine.
Three blades of differing widths are available for the Caterpillar 314C LR. The bolt-on cutting edge can be reused by turning it upside down. Rubber pads can be fitted over the standard track shoes to minimize ground damage. The compact radius makes the excavator a good choice for urban work, while the shorter tail swing radius provides tight-quarters operation. Power comes from the new Cat 3064 T compact engine—a low-noise, fuel-efficient plant. Other features include an enlarged cab and new window design. Sliding doors allow easy operator access, even in tight quarters.
A three-pump hydraulic system on the New Holland EC130 produces faster, smoother work cycles and also reduces fuel consumption and hydraulic oil heating. A dedicated swing pump provides top performance during combined swing and attachment function, allowing for four simultaneous movements without compromising attachment and swing speed. The operator can choose between either a backhoe operation pattern or an excavator operation pattern. The EC130 has a rating of 95 horsepower and a digging depth of 17 feet 8 inches.
The new CX135 from Case, part of the CX Series, has a 2 foot-1 inch swing radius for work under tight conditions. The soundproof cab is very roomy, with a skylight and sliding front window for ventilation and view. Heater and air conditioning are standard. The Isomount system cushions the cab from vibration for added comfort. The controls include selectable one-touch or auto accelerator/decelerator and one- or two-position mode selector. A power boost feature delivers added power in tough conditions.

Noteworthy features: Pro Control hydraulic system, high-pressure fuel injection engines, insulated cab with good visibility.
Inte-LX, the computer command control system on the Link-Belt 130LX, monitors hydraulic output, pressures, and regulates engine performance for the maximum balance between speed, power and fuel efficiency needed on the job. A two-speed boom and arm opening and closing function provides greater lifting speed, especially in swing/excavating simultaneous operations. Also, a built-in special cushion valve greatly reduces the shock and vibration at the end of each swing cycle.
Number of 20,000- to 40,000-lb. models: 2.
Noteworthy features: Nephron filtration system, fast cycle times, Inte-LX computer-controlled hydraulics, operator-friendly control station.
The cab on the Komatsu PC128US-2 employs a new convex-shaped cab that provides ample space throughout. Multi-position, pressure proportional control levers allow the operator to work in comfort while maintaining precise control. Viscous mountings dampen noise, with sliding convex doors making entrance easy in confined areas. With reduced tail swing, the machine occupies a road width of 11 feet 4 inches or less. Increased digging and dumping ranges provide a longer upper reach for jobs such as demolition or slope cutting.

New 20,000- to 40,000-lb. models: PC158USLC-2, PC160LC-7, PC138USLC-2.
The Machine Information Center on the Zaxis 135US from Hitachi captures and stores vital machine performance data such as engine speeds, hydraulic temperatures, pump pressures, alarms and faults, hours of operation, and more. The data can be downloaded through an mSeries Palm Pilot and transferred to a PC. Special PC software interprets the data and generates reports and graphs. A single work mode simplifies excavating operations. Engine speed is automatically controlled in response to the amount of lever operation.
