The knuckle boom crane is somewhat like a regular crane with one key difference. The boom can fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the middle. This allows the equipment 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 compared to boom truck cranes. The crane arm is designed to enable more payloads to be carried 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 kinds of knuckle boom cranes could be used without a certified crane operator, if the load capacity of the machinery 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, stand up and seated control. The radio remote systems are capable of running the crane and starting it. In addition, lots of models come equipped with a computer readout system which instantly provides system readouts reporting if the crane is overloaded or not.
