The knuckle boom crane is somewhat like a standard crane with one key difference. The boom could 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 storage and maneuvering.
Normally, the arm on a knuckle boom crane is quite a bit 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 entire bed of the truck empty.
Interestingly enough, smaller kinds of knuckle boom cranes could be utilized without a certified 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, stand up and seated control. The radio remote systems can run the crane and starting it. Moreover, lots of 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 contractors and maintenance professionals perform tasks 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 PAM Series and UL Series Personnel lifts have been designed and built so as to be easy for one person to operate. These machinery could be transported easily. They can easily pass through a regular sized doorway and be pushed into position smoothly. These lifts can be erected in minutes and can provide working heights of up to 46 feet, they are an efficient alternative to scaffold towers.
