world-famous Gradall boom
LOW WORKING PROFILE
The design of Gradall's telescoping, tilting boom allows it to work under trees, bridges, signs, ground floors of multi-story buildings and other challenging job locations where conventional knuckle booms simply will not fit. Watch the video animation below to see a side-by-side comparison of the Gradall boom versus a conventional knuckle boom.
Powered by the world's most advanced high-pressure, load-sensing hydraulics system, the telescoping design also delivers full power at any boom angle and through the entire dig cycle. That's a huge advantage over knuckle boom designs that suffer from a severe reduction in force at stick angles over 90°. Watch the video animation below to see the Gradall telescoping action crowd force vs the inconsistent knuckle boom.
Not only does the Gradall design increase boom push-pull capability, the full-length rotation delivers full attachment power at any angle – a versatility advantage as well as power edge over boom-end rotation devices.
BETTER BOOM VERSATILITY
Operators can see the full length of the boom while it's working, and they can use an in-cab switch to select the Gradall, Deere or SAE joystick pattern they prefer.
Every day in every corner of the world, the famous combination of boom power, versatility and productivity accomplishes everything from loading, excavating and demolishing to fine grading, ditching and sloping.
