The knuckle boom crane is quite like a standard crane with one key distinction. The boom is capable of folding back like a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machine to be able to transform into a compact size for maneuvering and storage.
Usually, the arm on a knuckle boom crane is somewhat a little lighter compared to boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Most knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Smaller types of knuckle boom cranes can be used without a certified crane operator, if the load capacity of the machinery is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
There are various kinds of control systems for the cranes. Like for example, there is 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. Furthermore, many models come outfitted with a computer readout system which provides system readouts immediately reporting if the crane is overloaded or not.
