A knuckle boom crane looks like a regular crane. The key distinction is that the boom could fold back like a finger because 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 somewhat a bit lighter compared to boom truck cranes. These crane arms are made to allow more payloads to be carried 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.
Smaller kinds of knuckle boom cranes could be used without a licensed crane operator, if the load capacity of the machinery is less than 15,000 pounds or if the boom's maximum length is less than 25 feet long.
Control systems for these cranes are normally different. Some could control from the ground, radio remote control, seated and stand up control. The radio remote systems can run the crane and starting it. Furthermore, a lot of models come equipped with a computer readout system that instantly provides system readouts reporting if the crane is overloaded or not.
