A knuckle boom crane looks like a standard crane. The key distinction is that the boom can fold back like a finger since the boom articulates at the "knuckle" near the middle. This enables the machinery to be able to transform into a compact size for maneuvering and storage.
Normally, the arm on a knuckle boom crane is somewhat a bit lighter than 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 behind the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller kinds of knuckle boom cranes could be used without a licensed crane operator, so long as the maximum capacity is less than 15,000 lbs. or if the maximum boom length is less than 25 feet long.
There are different types of control systems for the cranes. For example, there is 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. Furthermore, many models come outfitted with a computer readout system which provides system readouts immediately reporting if the crane is overloaded or not.
