The knuckle boom crane is somewhat like a regular crane with one key difference. The boom could fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machinery to be able to transform into a compact size for storage and maneuvering.
Normally, 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 at the rear of the cab. This leaves the whole bed of the truck empty.
Smaller models of knuckle boom cranes can be used without a licensed 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 kinds of control systems for the cranes. Like for instance, 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. Additionally, numerous 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 carry out tasks at elevated heights. These lifts are lightweight, portable, affordable work platforms made for interior use. The patented Girder Lock mast design by Snorkel provides superb flexibility and excellent reach. This system, used in the UL Series, offers great lift capacity.
The Snorkel PAM Series and UL Series Personnel lifts have been built and designed so as to be easy for one individual to utilize. These machinery are easy to transport. They can easily pass through a regular sized doorway and be pushed into position smoothly. These lifts are capable of being erected in minutes and being able to provide working heights of up to 46 feet, they truly are an effective alternative to scaffold towers.
