A knuckle boom crane looks similar to a regular crane. The main difference is that the boom can fold back like a finger because the boom articulates at the "knuckle" near the middle. This enables the machinery to be able to transform into a compact size for storage and maneuvering.
Normally, the arm on a knuckle boom crane is somewhat a little lighter than boom truck cranes. The crane arm is designed to allow more payloads to be lifted 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 kinds of knuckle boom cranes could be used 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 usually different. Some could control from the ground, radio remote control, seated and stand up control. The radio remote systems can operate the crane and starting it. Moreover, lots of models come equipped with a computer readout system which immediately provides system readouts reporting if the crane is overloaded or not.
