The knuckle boom crane is somewhat like a standard crane with one main distinction. The boom could fold back like a finger. In essence, the boom articulates at the "knuckle" near the middle. This allows the machinery to be able to transform into a compact size for storage and maneuvering.
Normally, the arm on a knuckle boom crane is quite a little lighter than boom truck cranes. The crane arm is designed to enable more payloads to be carried on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted at the rear of the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller models 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.
Control systems for these cranes are normally different. Some could control from the ground, radio remote control, stand up and seated control. The radio remote systems are capable of running the crane as well as starting it. Additionally, a lot of models come outfitted with a computer readout system which provides system readouts at once reporting if the crane is overloaded or not.
Personnel Lifts
Personnel lifts designed by Snorkel have been made to help maintenance professionals and contractors perform jobs at elevated heights. These lifts are portable, affordable, lightweight work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers superb flexibility and excellent reach. This system, used in the UL Series, offers excellent lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that just one person is needed to operate the equipment. These equipment are easy to transport. They could easily pass through a standard sized doorway and be pushed smoothly into position. These lifts are capable of being erected in minutes and being able to provide working heights of up to 46 feet, they truly are an efficient alternative to scaffold towers.
