The knuckle boom crane is quite similar to 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 middle. This enables the machinery to be able to transform into a compact size for maneuvering and storage.
Typically, the arm on a knuckle boom crane is quite a little lighter compared to boom truck cranes. The crane arm is designed to enable more payloads to be carried on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller kinds of knuckle boom cranes can be utilized without a licensed crane operator, so long as the maximum capacity is less than 15,000 pounds or if the maximum boom length is less than 25 feet long.
Control systems for these cranes are normally different. Some can control from the ground, radio remote control, seated and stand up control. The radio remote systems can operate the crane and starting it. Furthermore, numerous models come equipped with a computer readout system which provides system readouts immediately 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 tasks at elevated heights. These lifts are lightweight, portable, inexpensive work platforms made to be used indoor. 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 PAM Series and UL Series Personnel lifts have been designed and built in order to be easy for one person to operate. These equipment can 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 can provide working heights of up to 46 feet, they truly are an effective alternative to scaffold towers.
