The knuckle boom crane is quite like a typical crane with one key distinction. The boom can fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machine to be able to transform into a compact size for storage and maneuvering.
Usually, the arm on a knuckle boom crane is quite a bit lighter than 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 entire bed of the truck empty.
Smaller types of knuckle boom cranes could be used without a certified crane operator, if the load capacity of the machine 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 usually different. Some could control from the ground, radio remote control, seated and stand up control. The radio remote systems can operate the crane as well as starting it. In addition, many models come equipped with a computer readout system that instantly provides system readouts reporting if the crane is overloaded or not.
