A knuckle boom crane looks similar to a standard crane. The key distinction is that the boom can fold back similar to a finger as the boom articulates at the "knuckle" near the center. This allows the equipment to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are somewhat a little lighter compared to boom truck cranes. These crane arms are made to allow more payloads to be lifted on the back of the vehicle it is mounted on. Nearly all knuckle boom cranes are mounted at the rear of the cab. This leaves the whole bed of the truck empty.
Smaller types of knuckle boom cranes could be used without a certified crane operator, if the load capacity of the equipment 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. For example, there is radio remote control, control from the ground, seated and stand up control. The radio remote systems can operate the crane and starting it. Additionally, a lot of models come outfitted with a computer readout system that instantly provides system readouts 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 jobs at elevated heights. These lifts are lightweight, portable, affordable work platforms made to be used indoor. The patented Girder Lock mast design by Snorkel delivers excellent reach and superb stability. This system, utilized in the UL Series, offers great lift capacity.
The Snorkel UL Series Personnel and PAM Series lifts have been built and designed so as to be easy for one person to operate. These equipment are easy to transport. They could easily pass through a standard 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 are an effective alternative to scaffold towers.
