The knuckle boom crane is quite 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 maneuvering and storage.
Knuckle boom crane arms are quite a bit lighter than boom truck cranes. These crane arms are made to allow more payloads to be lifted on the back of the vehicle it is mounted on. 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 could be utilized without a certified crane operator, so 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 various kinds 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. Moreover, numerous models come equipped with a computer readout system that provides system readouts at once reporting if the crane is overloaded or not.
