A knuckle boom crane looks similar to a typical crane. The main difference is that the boom can fold back similar to a finger because 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 somewhat a little lighter than 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 behind the cab. This leaves the whole bed of the truck empty.
Smaller types of knuckle boom cranes could be utilized without a licensed crane operator, if the load capacity of the machinery is less than 15,000 pounds or if the boom's maximum length is less than 25 feet long.
There are various types of control systems for the cranes. Like for instance, there is control from the ground, radio remote control, seated and stand up 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 that provides system readouts immediately reporting if the crane is overloaded or not.
