A knuckle boom crane looks similar to a standard crane. The main difference is that the boom can fold back like a finger as the boom articulates at the "knuckle" near the middle. This allows the equipment to be able to transform into a compact size for maneuvering and storage.
Typically, the arm on a knuckle boom crane is quite a little lighter than boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Most knuckle boom cranes are mounted behind the cab. This leaves the whole bed of the truck empty.
Smaller models of knuckle boom cranes could be used without a certified crane operator, if the load capacity of the equipment is less than 15,000 pounds or if the boom's maximum length is less than 25 feet long.
There are different types 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 and starting it. In addition, numerous models come outfitted with a computer readout system which immediately provides system readouts reporting if the crane is overloaded or not.

Snorkel Personnel Lifts are designed for facilities maintenance professionals and contractors. These lifts are affordable, lightweight, portable work platforms made for interior use. The patented Girder Lock mast design by Snorkel provides excellent reach and superb stability. This system, used in the UL Series, provides excellent lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that just one individual is required to operate the machinery. These equipment could be transported easily. They could easily pass through a regular sized doorway and be pushed into position smoothly. These lifts are capable of being erected in minutes and being able to provide working heights of up to 46 feet, they are an efficient option to scaffold towers.
