XL5200 III Its long track provides a stable platform and can out dig and out maneuver anything in its weight class. Gradall is an excavator. What sets the gradall apart from conventional machines is the boom. The boom is similar to a human arm with wrist action, giving it the ability to move up, down, and side-to-side. The gradall has continuous boom force through the entire dig cycle with a 220 or 360 degree tilt, allowing the machine to handle fine grading and sloping. There are various attachments for the boom that can be interchanged in minutes such as various sized buckets, hammer, tamper and tunnel buckets, but the main attraction is the superboom attachment, which extends the reach of the arm from 30 to 52 feet.
