A knuckle boom crane looks similar to a regular crane. The main distinction is that the boom is capable of folding back like a finger since the boom articulates at the "knuckle" near the middle. 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 enable more payloads to be carried on the back of the vehicle it is mounted on. Nearly all 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 used without a certified 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.
Control systems for these cranes are normally different. Some can control from the ground, radio remote control, stand up and seated control. The radio remote systems can operate the crane as well as starting it. Furthermore, many models come outfitted with a computer readout system that provides system readouts immediately reporting if the crane is overloaded or not.
