A knuckle boom crane looks like a typical crane. The key distinction is that the boom can fold back similar to a finger as the boom articulates at the "knuckle" near the middle. 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 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 back of the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller kinds of knuckle boom cranes are capable of being utilized without a certified crane operator, as 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 various types of control systems for the cranes. For example, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems could run the crane as well as starting it. In addition, numerous models come equipped with a computer readout system that provides system readouts at once reporting if the crane is overloaded or not.
