The knuckle boom crane is quite like a typical crane with one key difference. The boom can fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machinery to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are quite a little lighter compared to boom truck cranes. These crane arms are made to allow 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 entire 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.
There are different types of control systems for the cranes. 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 and starting it. Moreover, many models come equipped with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.
