A knuckle boom crane looks similar to a regular crane. The key distinction is that the boom is capable of folding back similar to a finger since the boom articulates at the "knuckle" near the center. This allows the machine to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are quite a bit lighter compared to boom truck cranes. These crane arms are made to enable more payloads to be carried on the back of the vehicle it is mounted on. 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 kinds of control systems for the cranes. Like for example, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems are capable of running the crane as well as starting it. Moreover, many models come equipped with a computer readout system which provides system readouts immediately reporting if the crane is overloaded or not.
Personnel lifts designed by Snorkel have been made to help contractors and maintenance professionals perform tasks at elevated heights. These lifts are lightweight, portable, affordable work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers superb flexibility and excellent reach. This system, utilized in the UL Series, provides great lift capacity.
The Snorkel UL Series Personnel and PAM Series lifts have been designed and built in order to be easy for one person to operate. These machines are easy to transport. They could easily be pushed into position smoothly and pass through a regular sized doorway. These lifts could be erected in minutes and could provide working heights of up to 46 feet, they are an efficient alternative to scaffold towers.
