The knuckle boom crane is quite like a typical crane with one main distinction. The boom can fold back like 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 enable more payloads to be carried 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 could be utilized without a licensed 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 normally different. Some can control from the ground, radio remote control, stand up and seated control. The radio remote systems are capable of running the crane and starting it. Moreover, numerous models come outfitted with a computer readout system which provides system readouts at once reporting if the crane is overloaded or not.
