The knuckle boom crane is quite similar to a standard crane with one key distinction. The boom could fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This enables the machinery to be able to transform into a compact size for maneuvering and storage.
Usually, the arm on a knuckle boom crane is quite a little lighter than boom truck cranes. The crane arm is designed to enable more payloads to be lifted on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the whole bed of the truck empty.
Smaller models of knuckle boom cranes could be used without a certified crane operator, if the load capacity of the machinery is less than 15,000 pounds 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, seated and stand up control. The radio remote systems can run the crane and starting it. Additionally, many models come outfitted with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.
