The knuckle boom crane is quite similar to a standard crane with one key distinction. The boom is capable of folding back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This enables the equipment to be able to transform into a compact size for maneuvering and storage.
Knuckle boom crane arms are somewhat a bit lighter compared to 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 at the rear of the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes can 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 different types of control systems for the cranes. Like for instance, there is control from the ground, radio remote control, seated and stand up control. The radio remote systems can operate the crane as well as starting it. Moreover, many models come outfitted with a computer readout system that provides system readouts at once reporting if the crane is overloaded or not.
