MENUMENU

The XL 4330 V Gradall is an on/off highway excavator that can work at the front, rear or either side of the undercarriage without the need for outriggers. This design allows for greater efficiency—no need to stop work to lower outriggers—and provides stable operation, enabling it to pick and carry cargo around job sites.

 

Weighing 43,580 pounds, the XL 4300 V model has a maximum speed of 18 mph both on and off pavement.

Designed and built by Gradall Industries Inc., the XL 4300 V also features the new Tier-4 Final compliant Volvo Penta diesel engine—including the demanding Stage IV (EU) and Tier-4 Final (US) emission reduction requirements. With 173 horsepower @ 2200 rpm (129 kW), the XL 4300 V’s fuel efficiency is improved by up to 5 percent.

 

Along with the new engine, Series V excavators include an upgraded 24-volt electrical system. An operator cab safety option provides rollover protection that meets safety test requirements and is integrated within the existing cab structure, without external support.

The XL 4300 V has a maximum reach of 30 feet, 4 inches at grade and a maximum dig depth of 21 feet, 3 inches. The model’s rated bucket breakout force is 25,405 pounds and the rated boom force is 22,075 pounds.

 

The rubber tire undercarriage provides a stable work platform and will not damage concrete or asphalt surfaces. Options include outriggers and a grading blade for further stability.

 

Mobility is enhanced by a full-time, 4-wheel drive transfer case that delivers power from the hydraulic drive motor to the drive axles. Both axles have wet-disc brakes.

 

The Gradall telescoping, full-tilting boom can precisely position excavating and demolition attachments without losing power. The Gradall boom design also creates a low working profile, enabling the machine to work under bridges, in tunnels and under overhead obstructions. A short tail swing allows the machine to work in tight spaces and along highways with minimal traffic interruption.

 

The operator cab has a full view of the entire boom during the complete dig cycle and offers sound-deadening capabilities, a large seat with built-in joysticks, and a switch that allows the operator to select the Gradall, Deere or SAE joystick pattern. Repositioning is accomplished with foot pedals.

A host of attachments are available for the XL 4300 V, including excavating, trenching, pavement removal, ditching and dredging buckets. Also available are grading blades, boom extensions, limb shearers, fixed thumb grapple and live booms.
