A knuckle boom crane looks similar to a standard crane. The key distinction is that the boom is capable of folding back like a finger since 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.
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 behind the cab. This leaves the entire bed of the truck empty.
Smaller types 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.
Control systems for these cranes are often different. Some could control from the ground, radio remote control, seated and stand up control. The radio remote systems can run the crane and starting it. Additionally, many 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 carry out jobs at elevated heights. These lifts are affordable, lightweight, portable work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers excellent reach and superb stability. This system, used in the UL Series, provides excellent lift capacity.
The Snorkel UL Series Personnel and PAM Series lifts have been designed and built so as to be easy for one individual to utilize. These machinery are easy to transport. They could easily pass through a standard sized doorway and be pushed into position smoothly. These lifts can be erected in minutes and could provide working heights of up to 46 feet, they really are an efficient option to scaffold towers.
