A knuckle boom crane looks similar to a standard crane. The main distinction is that the boom is capable of folding back similar to a finger since 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.
Usually, the arm on a knuckle boom crane is somewhat a bit lighter compared to boom truck cranes. The crane arm is designed to allow more payloads to be lifted on the back of the mounted vehicle. Most knuckle boom cranes are mounted at the back of the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller kinds of knuckle boom cranes could be utilized without a licensed crane operator, as long as the maximum capacity is less than 15,000 lbs. or if the maximum boom length is less than 25 feet long.
Control systems for these cranes are normally different. Some can control from the ground, radio remote control, stand up and seated control. The radio remote systems could run the crane as well as starting it. Moreover, many models come outfitted with a computer readout system that provides system readouts immediately reporting if the crane is overloaded or not.
