The knuckle boom crane is somewhat like a standard crane with one key difference. The boom could fold back like a finger. In essence, 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. Most knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Smaller models of knuckle boom cranes can be used without a certified crane operator, if the load capacity of the machinery is less than 15,000 pounds or if the boom's maximum 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, seated and stand up control. The radio remote systems are capable of running the crane and starting it. Additionally, many models come outfitted with a computer readout system which instantly provides system readouts reporting if the crane is overloaded or not.
