The knuckle boom crane is somewhat similar to a regular crane with one key distinction. The boom could fold back like a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machine 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 allow more payloads to be lifted on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller kinds of knuckle boom cranes are capable of being 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 different kinds 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 operate the crane as well as starting it. In addition, many models come outfitted with a computer readout system which provides system readouts immediately 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 tasks at elevated heights. These lifts are portable, inexpensive, lightweight work platforms made to be used indoor. The patented Girder Lock mast design by Snorkel delivers excellent reach and superb stability. This system, utilized in the UL Series, offers excellent lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that just one individual is required to operate the equipment. These machines are easy to transport. They can easily be pushed into position smoothly and pass through a standard sized doorway. 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 alternative to scaffold towers.
