A knuckle boom crane looks similar to a typical crane. The key difference is that the boom is capable of folding back like a finger since 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 back of the cab. This leaves the whole bed of the truck empty.
Smaller kinds of knuckle boom cranes could be utilized without a licensed crane operator, if the load capacity of the machinery is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
There are different types 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 run the crane as well as starting it. Furthermore, numerous models come equipped with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.
