The knuckle boom crane is somewhat similar to a standard crane with one key difference. The boom could fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the middle. This enables the machine to be able to transform into a compact size for maneuvering and storage.
Usually, the arm on a knuckle boom crane is quite a bit lighter compared to boom truck cranes. The crane arm is designed to enable more payloads to be lifted 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 kinds 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.
There are various 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 are capable of running 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.
