The knuckle boom crane is somewhat similar to a typical crane with one key distinction. The boom is capable of folding 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 storage and maneuvering.
Knuckle boom crane arms are quite a bit lighter compared to boom truck cranes. These crane arms are made to allow more payloads to be lifted 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.
Smaller models of knuckle boom cranes could be used without a certified crane operator, if the load capacity of the equipment is less than 15,000 pounds or if the boom's maximum length is less than 25 feet long.
There are different kinds of control systems for the cranes. For instance, there is control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane as well as starting it. Moreover, numerous models come outfitted with a computer readout system which provides system readouts immediately reporting if the crane is overloaded or not.
