The knuckle boom crane is quite similar to a typical crane with one main difference. The boom is capable of folding back like a finger. In essence, the boom articulates at the "knuckle" near the center. This enables the equipment to be able to transform into a compact size for maneuvering and storage.
Knuckle boom crane arms are somewhat a little lighter than boom truck cranes. These crane arms are made to enable more payloads to be carried on the back of the vehicle it is mounted on. Nearly all knuckle boom cranes are mounted at the rear of 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 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, seated and stand up control. The radio remote systems are capable of running the crane and starting it. Moreover, numerous models come equipped with a computer readout system that instantly provides system readouts reporting if the crane is overloaded or not.
