A knuckle boom crane looks similar to a typical crane. The key difference is that the boom can fold back like a finger as the boom articulates at the "knuckle" near the center. This allows the machine 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 enable more payloads to be lifted on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted at the rear of the cab. This leaves the entire bed of the truck empty.
Smaller models of knuckle boom cranes can be utilized without a licensed crane operator, if the load capacity of the equipment 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, seated and stand up control. The radio remote systems are capable of running the crane and starting it. In addition, many models come equipped with a computer readout system which immediately provides system readouts reporting if the crane is overloaded or not.
