A knuckle boom crane looks like a standard crane. The key distinction is that the boom is capable of folding back similar to a finger because the boom articulates at the "knuckle" near the middle. This allows the machinery to be able to transform into a compact size for maneuvering and storage.
Normally, the arm on a knuckle boom crane is somewhat a bit lighter compared to boom truck cranes. The crane arm is designed to enable more payloads to be carried 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.
Smaller models of knuckle boom cranes could be utilized without a licensed crane operator, if the load capacity of the equipment is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
Control systems for these cranes are normally different. Some can control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane and starting it. Furthermore, numerous models come equipped with a computer readout system that provides system readouts immediately reporting if the crane is overloaded or not.
