The knuckle boom crane is quite similar to a standard crane with one main distinction. The boom is capable of folding back similar to a finger. In essence, the boom articulates at the "knuckle" near the middle. This allows the equipment to be able to transform into a compact size for storage and maneuvering.
Usually, the arm on a knuckle boom crane is somewhat 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. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the entire bed of the truck empty.
Smaller types of knuckle boom cranes could be used without a licensed crane operator, if the load capacity of the equipment 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 usually different. Some can control from the ground, radio remote control, stand up and seated control. The radio remote systems can operate the crane and starting it. Furthermore, lots of models come equipped with a computer readout system that instantly provides system readouts reporting if the crane is overloaded or not.
