The knuckle boom crane is quite like a typical crane with one key difference. The boom could fold 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 maneuvering and storage.
Typically, the arm on a knuckle boom crane is somewhat a bit lighter than boom truck cranes. The crane arm is designed to allow more payloads to be lifted 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 kinds of knuckle boom cranes could be used without a licensed 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 different kinds of control systems for the cranes. For example, there is control from the ground, radio remote control, seated and stand up control. The radio remote systems can operate the crane as well as starting it. Additionally, numerous models come outfitted with a computer readout system which instantly provides system readouts reporting if the crane is overloaded or not.
