A knuckle boom crane looks like a typical crane. The main distinction is that the boom can fold back like a finger because the boom articulates at the "knuckle" near the center. This enables the machine to be able to transform into a compact size for storage and maneuvering.
Usually, the arm on a knuckle boom crane is somewhat a bit lighter than boom truck cranes. The crane arm is designed to enable more payloads to be lifted on the back of the mounted vehicle. Most knuckle boom cranes are mounted at the back of the cab. This leaves the whole bed of the truck empty.
Smaller models of knuckle boom cranes can 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 often different. Some can control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane as well as starting it. Additionally, numerous models come outfitted with a computer readout system which instantly provides system readouts reporting if the crane is overloaded or not.
