The knuckle boom crane is somewhat similar to a standard crane with one main difference. The boom is capable of folding back like 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 enable more payloads to be carried on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted at the back of the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller kinds of knuckle boom cranes could be utilized without a licensed crane operator, so long as the maximum capacity is less than 15,000 lbs. or if the maximum boom length is less than 25 feet long.
Control systems for these cranes are usually different. Some could control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane and starting it. Furthermore, numerous models come outfitted with a computer readout system that provides system readouts at once reporting if the crane is overloaded or not.
