The knuckle boom crane is somewhat similar to a standard crane with one main distinction. The boom can fold back like a finger. In essence, the boom articulates at the "knuckle" near the middle. This enables the machinery to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are quite a bit lighter compared to boom truck cranes. These crane arms are made to enable more payloads to be lifted on the back of the vehicle it is mounted on. Nearly all 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 are capable of being used without a certified crane operator, as long as the maximum capacity is less than 15,000 pounds or if the maximum boom length is less than 25 feet long.
Control systems for these cranes are usually different. Some can control from the ground, radio remote control, seated and stand up control. The radio remote systems could operate the crane and starting it. Furthermore, a lot of models come outfitted with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.
