The knuckle boom crane is somewhat like a standard 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 machine to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are quite a bit lighter than boom truck cranes. These crane arms are made to allow more payloads to be carried on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes can be used without a licensed 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 kinds of control systems for the cranes. Like for example, there is radio remote control, control from the ground, seated and stand up control. The radio remote systems could run the crane as well as starting it. Moreover, numerous models come equipped with a computer readout system that instantly provides system readouts reporting if the crane is overloaded or not.
