The knuckle boom crane is somewhat like a typical crane with one main difference. The boom is capable of folding back similar to a finger. In essence, 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.
Typically, the arm on a knuckle boom crane is quite a bit lighter than boom truck cranes. The crane arm is designed to enable more payloads to be lifted on the back of the mounted vehicle. 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 could be 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 various kinds of control systems for the cranes. Like for instance, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems are capable of running the crane and starting it. Furthermore, numerous 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 contractors and maintenance professionals perform jobs at elevated heights. These lifts are lightweight, portable, inexpensive 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 PAM Series and UL Series Personnel lifts have been designed and built so as to be easy for one person to operate. These equipment are easy to transport. They can easily be pushed smoothly into position and pass through a regular sized doorway. These lifts could be erected in minutes and can provide working heights of up to 46 feet, they are an efficient option to scaffold towers.
