A knuckle boom crane looks similar to a regular crane. The key difference is that the boom is capable of folding back like a finger as the boom articulates at the "knuckle" near the center. This allows the machinery to be able to transform into a compact size for storage and maneuvering.
Normally, the arm on a knuckle boom crane is quite a little lighter than boom truck cranes. The crane arm is designed to allow more payloads to be lifted on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted at the rear of the cab. This leaves the whole bed of the truck empty.
Smaller types of knuckle boom cranes can be utilized without a certified crane operator, if the load capacity of the machine 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 usually 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 as well as starting it. In addition, many models come outfitted with a computer readout system that provides system readouts at once reporting if the crane is overloaded or not.
