The knuckle boom crane is somewhat similar to a standard crane with one main 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.
Knuckle boom crane arms are quite 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 behind the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller models of knuckle boom cranes are capable of being used without a licensed 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.
There are different types of control systems for the cranes. Like for instance, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems are capable of running the crane and starting it. Moreover, numerous models come equipped with a computer readout system which provides system readouts immediately reporting if the crane is overloaded or not.
