A knuckle boom crane looks similar to a standard crane. The main distinction is that the boom is capable of folding back like a finger because the boom articulates at the "knuckle" near the middle. This allows the equipment to be able to transform into a compact size for maneuvering and storage.
Usually, the arm on a knuckle boom crane is quite a bit lighter than boom truck cranes. The crane arm is designed to allow more payloads to be lifted on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted at the rear of the cab. This leaves the entire bed of the truck empty.
Smaller types 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.
There are different kinds of control systems for the cranes. Like for example, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems are capable of running the crane as well as starting it. Additionally, many models come outfitted with a computer readout system which provides system readouts immediately reporting if the crane is overloaded or not.
