The knuckle boom crane is somewhat similar to a standard crane with one main distinction. The boom could fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This enables the machinery 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 at the back of the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes could be used without a licensed 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 normally different. Some could 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. Furthermore, many models come equipped with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.
