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 middle. This enables the machine to be able to transform into a compact size for maneuvering and storage.
Usually, the arm on a knuckle boom crane is quite a bit lighter compared to boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller models of knuckle boom cranes are capable of being utilized without a licensed crane operator, so long as the maximum capacity is less than 15,000 lbs. or if the maximum boom length is less than 25 feet long.
There are different kinds of control systems for the cranes. For example, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems are capable of running the crane and starting it. In addition, many models come outfitted with a computer readout system that provides system readouts immediately reporting if the crane is overloaded or not.
