A knuckle boom crane looks similar to a standard crane. The key distinction is that the boom is capable of folding back like a finger since the boom articulates at the "knuckle" near the middle. This allows the equipment to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are somewhat a bit 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 whole bed of the truck empty.
Smaller kinds of knuckle boom cranes could be used without a licensed crane operator, if the load capacity of the machine is less than 15,000 pounds or if the boom's maximum length is less than 25 feet long.
There are different kinds of control systems for the cranes. Like for example, there is radio remote control, control from the ground, seated and stand up control. The radio remote systems are capable of running the crane as well as starting it. Furthermore, a lot of models come equipped with a computer readout system which immediately provides system readouts reporting if the crane is overloaded or not.
