A knuckle boom crane looks like a standard crane. The key difference is that the boom can fold back like a finger because the boom articulates at the "knuckle" near the center. This enables the machine to be able to transform into a compact size for maneuvering and storage.
Usually, the arm on a knuckle boom crane is quite a little 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.
Interestingly enough, smaller types of knuckle boom cranes could be utilized without a licensed crane operator, as long as the maximum capacity is less than 15,000 pounds or if the maximum boom length is less than 25 feet long.
There are various kinds of control systems for the cranes. For instance, there is 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 immediately provides system readouts reporting if the crane is overloaded or not.
