A knuckle boom crane looks similar to a standard crane. The key difference is that the boom could 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 maneuvering and storage.
Usually, the arm on a knuckle boom crane is somewhat a bit lighter compared to boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the whole bed of the truck empty.
Smaller models of knuckle boom cranes can be used without a certified crane operator, if the load capacity of the equipment is less than 15,000 lbs. 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 could run the crane as well as starting it. Moreover, numerous models come equipped with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.
