A knuckle boom crane looks similar to a standard crane. The key distinction is that the boom can fold back similar to a finger as the boom articulates at the "knuckle" near the center. This allows the machine 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 allow 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 entire bed of the truck empty.
Smaller models of knuckle boom cranes can be utilized without a licensed crane operator, if the load capacity of the machine 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 usually different. Some could control from the ground, radio remote control, stand up and seated control. The radio remote systems can operate the crane as well as starting it. In addition, many models come outfitted with a computer readout system which immediately provides system readouts reporting if the crane is overloaded or not.
