The knuckle boom crane is quite similar to a regular crane with one main distinction. The boom can fold back like a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the equipment to be able to transform into a compact size for maneuvering and storage.
Normally, the arm on a knuckle boom crane is quite a little lighter than boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Most 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 equipment 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 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 as well as starting it. In addition, numerous models come equipped with a computer readout system that provides system readouts immediately reporting if the crane is overloaded or not.
