A knuckle boom crane looks similar to a standard crane. The key distinction is that the boom can fold back similar to a finger because the boom articulates at the "knuckle" near the center. This allows the machinery to be able to transform into a compact size for maneuvering and storage.
Knuckle boom crane arms are somewhat a little lighter than boom truck cranes. These crane arms are made to enable more payloads to be lifted on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Smaller models of knuckle boom cranes could be used without a certified crane operator, if the load capacity of the machine 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 could control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane and starting it. Furthermore, numerous models come equipped with a computer readout system which instantly provides system readouts reporting if the crane is overloaded or not.
