A knuckle boom crane looks like a standard crane. The key difference is that the boom can fold back similar to 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 maneuvering and storage.
Knuckle boom crane arms are quite a little 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 behind the cab. This leaves the entire bed of the truck empty.
Smaller kinds of knuckle boom cranes could be used 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 usually different. Some could control from the ground, radio remote control, stand up and seated control. The radio remote systems could run the crane and starting it. In addition, numerous models come equipped with a computer readout system that provides system readouts immediately reporting if the crane is overloaded or not.
