A knuckle boom crane looks like a regular crane. The key distinction is that the boom could fold back like a finger since the boom articulates at the "knuckle" near the middle. This allows the equipment to be able to transform into a compact size for maneuvering and storage.
Usually, the arm on a knuckle boom crane is somewhat a bit lighter than boom truck cranes. The crane arm is designed to enable more payloads to be lifted on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Smaller kinds of knuckle boom cranes can be used without a certified crane operator, if the load capacity of the equipment 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 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 and starting it. Additionally, a lot of models come outfitted with a computer readout system which instantly provides system readouts reporting if the crane is overloaded or not.
