The knuckle boom crane is somewhat like a regular crane with one key distinction. The boom is capable of folding back similar to a finger. In essence, the boom articulates at the "knuckle" near the middle. This enables the machinery to be able to transform into a compact size for maneuvering and storage.
Knuckle boom crane arms are somewhat a bit lighter compared to boom truck cranes. These crane arms are made to allow more payloads to be carried on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Smaller types of knuckle boom cranes could 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 could control from the ground, radio remote control, stand up and seated control. The radio remote systems could operate the crane as well as starting it. In addition, many models come equipped with a computer readout system that provides system readouts at once reporting if the crane is overloaded or not.
