The knuckle boom crane is somewhat similar to a typical crane with one main difference. The boom could fold back similar to a finger. In essence, 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 bit lighter compared to boom truck cranes. These crane arms are made to allow more payloads to be lifted on the back of the vehicle it is mounted on. 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 utilized without a licensed 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 normally 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. Moreover, many models come equipped with a computer readout system which instantly provides system readouts reporting if the crane is overloaded or not.
