A knuckle boom crane looks similar to a regular crane. The key distinction is that the boom could fold back like a finger since the boom articulates at the "knuckle" near the middle. This enables the machine 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 than 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 could be utilized without a certified crane operator, if the load capacity of the machinery is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
Control systems for these cranes are usually different. Some could control from the ground, radio remote control, stand up and seated control. The radio remote systems could run the crane as well as starting it. In addition, numerous models come outfitted with a computer readout system that provides system readouts at once 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 inexpensive, lightweight, portable 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, provides great 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 utilize. These machines are easy to transport. They could easily be pushed smoothly into position and pass through a standard sized doorway. 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 option to scaffold towers.
