The knuckle boom crane is quite similar to a standard crane with one main difference. The boom could fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This enables the machine to be able to transform into a compact size for maneuvering and storage.
Typically, the arm on a knuckle boom crane is somewhat a bit lighter compared to boom truck cranes. The crane arm is designed to enable more payloads to be lifted 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.
Smaller models of knuckle boom cranes can be used without a certified crane operator, if the load capacity of the machinery is less than 15,000 pounds or if the boom's maximum 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, seated and stand up control. The radio remote systems are capable of running the crane and starting it. Moreover, numerous models come equipped with a computer readout system which immediately 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 carry out tasks at elevated heights. These lifts are portable, inexpensive, lightweight 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, offers great lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that just one individual is needed to operate the equipment. These machinery could be transported easily. They can easily pass through a regular 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 really are an efficient option to scaffold towers.
