The knuckle boom crane is quite similar to a standard crane with one key difference. The boom could fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the middle. This enables the machine to be able to transform into a compact size for maneuvering and storage.
Typically, the arm on a knuckle boom crane is somewhat a little lighter compared to 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 rear of the cab. This leaves the whole bed of the truck empty.
Smaller models of knuckle boom cranes could be utilized without a licensed 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 could control from the ground, radio remote control, stand up and seated control. The radio remote systems could run the crane as well as starting it. Furthermore, many models come outfitted with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.
