The knuckle boom crane is quite similar to a standard crane with one key difference. The boom is capable of folding back like a finger. In essence, the boom articulates at the "knuckle" near the center. This enables the machinery to be able to transform into a compact size for storage and maneuvering.
Typically, the arm on a knuckle boom crane is somewhat a bit lighter than 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 behind the cab. This leaves the whole bed of the truck empty.
Smaller types of knuckle boom cranes could 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.
There are various types of control systems for the cranes. For example, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems are capable of running the crane and starting it. In addition, numerous models come outfitted with a computer readout system which instantly provides system readouts reporting if the crane is overloaded or not.
