A knuckle boom crane looks like a standard crane. The main difference 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 machinery to be able to transform into a compact size for maneuvering and storage.
Knuckle boom crane arms are quite a little lighter compared to boom truck cranes. These crane arms are made to enable more payloads to be lifted on the back of the vehicle it is mounted on. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes could be used without a certified crane operator, as long as the maximum capacity is less than 15,000 pounds 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 are capable of running the crane as well as starting it. In addition, lots of models come equipped with a computer readout system which provides system readouts immediately reporting if the crane is overloaded or not.
