The knuckle boom crane is quite like a typical crane with one key difference. The boom could fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the middle. This enables the equipment to be able to transform into a compact size for maneuvering and storage.
Normally, the arm on a knuckle boom crane is quite a little lighter compared to boom truck cranes. The crane arm is designed to allow more payloads to be lifted on the back of the mounted vehicle. Most knuckle boom cranes are mounted at the rear of the cab. This leaves the whole bed of the truck empty.
Smaller models of knuckle boom cranes could be utilized 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 usually different. Some could 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. Moreover, numerous models come outfitted with a computer readout system which immediately provides system readouts reporting if the crane is overloaded or not.
