A knuckle boom crane looks like a standard crane. The key distinction is that the boom could fold back like a finger because the boom articulates at the "knuckle" near the middle. This enables the machine to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are quite a bit 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 at the back of the cab. This leaves the whole bed of the truck empty.
Smaller models of knuckle boom cranes can be used without a licensed crane operator, if the load capacity of the machinery is less than 15,000 pounds or if the boom's maximum length is less than 25 feet long.
There are various 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. Furthermore, many models come outfitted with a computer readout system which immediately provides system readouts reporting if the crane is overloaded or not.
Personnel Lifts
Personnel lifts designed by Snorkel have been made to help maintenance professionals and contractors carry out jobs at elevated heights. These lifts are affordable, lightweight, portable work platforms made to be used indoor. The patented Girder Lock mast design by Snorkel delivers superb flexibility and excellent reach. This system, used in the UL Series, provides great lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that only one individual is required to operate the machinery. These machines are easy to transport. They could easily be pushed smoothly into position and pass through a regular sized doorway. These lifts could be erected in minutes and being able to provide working heights of up to 46 feet, they are an efficient option to scaffold towers.
