A knuckle boom crane looks like a typical crane. The main distinction is that the boom can fold back similar to a finger as the boom articulates at the "knuckle" near the center. This allows the machine to be able to transform into a compact size for maneuvering and storage.
Typically, the arm on a knuckle boom crane is somewhat a bit lighter than boom truck cranes. The crane arm is designed to enable more payloads to be carried on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted at the rear of the cab. This leaves the entire bed of the truck empty.
Smaller models of knuckle boom cranes can be used without a licensed 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.
There are various types of control systems for the cranes. Like for instance, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems can run the crane as well as starting it. Additionally, many models come outfitted with a computer readout system which provides system readouts at once reporting if the crane is overloaded or not.
