The knuckle boom crane is quite similar to a standard crane with one main distinction. The boom is capable of folding back like a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machine to be able to transform into a compact size for storage and maneuvering.
Usually, the arm on a knuckle boom crane is quite a bit lighter than boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Most knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Smaller kinds of knuckle boom cranes can be used without a licensed crane operator, if the load capacity of the machine is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
Control systems for these cranes are often different. Some can control from the ground, radio remote control, stand up and seated control. The radio remote systems can run the crane and starting it. In addition, a lot of models come equipped with a computer readout system that instantly provides system readouts reporting if the crane is overloaded or not.
