A knuckle boom crane looks similar to a standard crane. The main distinction is that the boom could fold back like a finger since the boom articulates at the "knuckle" near the middle. This enables the machinery to be able to transform into a compact size for maneuvering and storage.
Knuckle boom crane arms are quite a bit lighter than boom truck cranes. These crane arms are made to enable more payloads to be lifted on the back of the vehicle it is mounted on. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the entire bed of the truck empty.
Smaller kinds 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.
Control systems for these cranes are usually different. Some can control from the ground, radio remote control, stand up and seated control. The radio remote systems could operate the crane as well as starting it. Moreover, a lot of models come outfitted with a computer readout system that 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 portable, affordable, lightweight 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 excellent lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that only one person is needed to operate the equipment. These equipment are easy to transport. They can easily pass through a standard sized doorway and be pushed smoothly into position. These lifts could be erected in minutes and being able to provide working heights of up to 46 feet, they are an effective option to scaffold towers.
