The knuckle boom crane is somewhat similar to a typical crane with one key difference. The boom can 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.
Knuckle boom crane arms are somewhat a bit lighter than boom truck cranes. These crane arms are made to enable more payloads to be lifted on the back of the vehicle it is mounted on. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes can be used without a licensed crane operator, so long as the maximum capacity is less than 15,000 lbs. or if the maximum boom length is less than 25 feet long.
There are various types of control systems for the cranes. For example, there is control from the ground, radio remote control, seated and stand up control. The radio remote systems can run the crane and starting it. Moreover, numerous models come equipped with a computer readout system that provides system readouts immediately reporting if the crane is overloaded or not.
