A knuckle boom crane looks similar to a standard crane. The main distinction is that the boom could fold back like a finger as 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.
Knuckle boom crane arms are somewhat 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. Nearly all 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 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 different 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 can operate the crane and starting it. Furthermore, many models come equipped with a computer readout system which immediately provides system readouts reporting if the crane is overloaded or not.
