The knuckle boom crane is somewhat like a regular crane with one key difference. The boom is capable of folding back similar to a finger. In essence, 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.
Typically, the arm on a knuckle boom crane is somewhat a little lighter than boom truck cranes. The crane arm is designed to allow more payloads to be lifted on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the entire bed of the truck empty.
Smaller types of knuckle boom cranes can be utilized without a certified 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.
Control systems for these cranes are often different. Some could control from the ground, radio remote control, stand up and seated control. The radio remote systems can run the crane and starting it. Moreover, numerous models come outfitted with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.
