A knuckle boom crane looks similar to a typical crane. The main distinction is that the boom could 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 maneuvering and storage.
Typically, the arm on a knuckle boom crane is somewhat a little lighter compared to boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the whole bed of the truck empty.
Smaller kinds of knuckle boom cranes can be utilized without a licensed 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.
Control systems for these cranes are often different. Some could control from the ground, radio remote control, stand up and seated control. The radio remote systems are capable of running the crane as well as starting it. Furthermore, many models come outfitted with a computer readout system which 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 perform tasks at elevated heights. These lifts are lightweight, portable, inexpensive work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers superb flexibility and excellent reach. 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 machinery. These machinery could be transported easily. They could easily be pushed into position smoothly and pass through a regular sized doorway. These lifts are capable of being erected in minutes and could provide working heights of up to 46 feet, they are an effective option to scaffold towers.
