The knuckle boom crane is quite like a regular crane with one key distinction. The boom could fold back like a finger. In essence, the boom articulates at the "knuckle" near the center. This enables the machinery to be able to transform into a compact size for maneuvering and storage.
Normally, the arm on a knuckle boom crane is quite a little lighter compared to boom truck cranes. The crane arm is designed to allow more payloads to be lifted on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller types 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 different types of control systems for the cranes. For instance, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems could operate the crane as well as starting it. Additionally, many models come equipped with a computer readout system which instantly 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 perform jobs at elevated heights. These lifts are affordable, lightweight, portable work platforms made for interior use. The patented Girder Lock mast design by Snorkel provides excellent reach and superb stability. This system, used in the UL Series, provides excellent lift capacity.
The Snorkel PAM Series and UL Series Personnel lifts have been built and designed in order to be easy for one person to utilize. These equipment can be transported easily. They can easily be pushed into position smoothly 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 alternative to scaffold towers.
