The knuckle boom crane is quite similar to 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 middle. This allows the machine to be able to transform into a compact size for maneuvering and storage.
Normally, the arm on a knuckle boom crane is quite a little lighter than boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Most knuckle boom cranes are mounted at the rear of the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller kinds 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 lbs. or if the maximum boom length is less than 25 feet long.
Control systems for these cranes are usually different. Some could control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane and starting it. Moreover, numerous models come outfitted with a computer readout system that instantly provides system readouts reporting if the crane is overloaded or not.
