A knuckle boom crane looks like a regular crane. The main difference is that the boom is capable of folding back like a finger as the boom articulates at the "knuckle" near the center. This enables the machine to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are quite a little lighter than boom truck cranes. These crane arms are made to allow more payloads to be lifted 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 whole 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 machinery is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
Control systems for these cranes are normally different. Some can 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.
