The knuckle boom crane is somewhat like a typical crane with one key distinction. The boom could fold back like a finger. In essence, the boom articulates at the "knuckle" near the center. This enables the machinery to be able to transform into a compact size for storage and maneuvering.
Normally, the arm on a knuckle boom crane is somewhat 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 behind the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes are capable of being used without a certified crane operator, as long as the maximum capacity is less than 15,000 pounds or if the maximum boom length is less than 25 feet long.
Control systems for these cranes are often 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. Furthermore, many models come equipped with a computer readout system which provides system readouts immediately reporting if the crane is overloaded or not.
