A knuckle boom crane looks like a regular crane. The key difference is that the boom is capable of folding back like a finger as the boom articulates at the "knuckle" near the center. This allows the equipment to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are somewhat a bit lighter than boom truck cranes. These crane arms are made to enable more payloads to be lifted on the back of the vehicle it is mounted on. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the entire 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 machine 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 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, lots of models come outfitted with a computer readout system that instantly provides system readouts reporting if the crane is overloaded or not.
