The knuckle boom crane is somewhat similar to 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 little lighter than boom truck cranes. These crane arms are made to allow more payloads to be lifted on the back of the vehicle it is mounted on. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller kinds of knuckle boom cranes can be used without a certified crane operator, as long as the maximum capacity is less than 15,000 lbs. or if the maximum boom 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 outfitted with a computer readout system that provides system readouts immediately reporting if the crane is overloaded or not.
