The knuckle boom crane is quite like a regular crane with one main distinction. The boom can fold back like a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machinery to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are quite a little lighter compared to boom truck cranes. These crane arms are made to enable more payloads to be carried 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 entire bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes are capable of being utilized 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 types of control systems for the cranes. Like for example, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems are capable of running the crane as well as starting it. In addition, many models come equipped 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 inexpensive, lightweight, portable 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, provides excellent lift capacity.
The Snorkel UL Series Personnel and PAM Series lifts have been designed and built in order to be easy for one person to utilize. These machines could be transported easily. 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 are an efficient alternative to scaffold towers.
