The knuckle boom crane is somewhat similar to a standard crane with one main distinction. The boom can fold back similar to 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 storage and maneuvering.
Typically, the arm on a knuckle boom crane is somewhat a little lighter compared to 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.
Interestingly enough, smaller models of knuckle boom cranes can be utilized without a certified crane operator, as long as the maximum capacity is less than 15,000 lbs. or if the maximum boom length is less than 25 feet long.
There are different kinds of control systems for the cranes. Like for instance, there is radio remote control, control from the ground, seated and stand up control. The radio remote systems are capable of running the crane as well as starting it. Additionally, many models come equipped with a computer readout system which instantly provides system readouts reporting if the crane is overloaded or not.
