A knuckle boom crane looks like a standard crane. The main difference is that the boom can fold back like a finger as the boom articulates at the "knuckle" near the middle. This allows the machinery to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are somewhat 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 behind the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes could be utilized without a certified crane operator, as long as the maximum capacity is less than 15,000 lbs. or if the maximum boom length is less than 25 feet long.
There are different types of control systems for the cranes. Like for instance, there is control from the ground, radio remote control, stand up and seated control. The radio remote systems are capable of running the crane as well as starting it. In addition, many models come equipped with a computer readout system which provides system readouts at once reporting if the crane is overloaded or not.
