A knuckle boom crane looks similar to a standard 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 middle. This allows the equipment to be able to transform into a compact size for maneuvering and storage.
Usually, the arm on a knuckle boom crane is quite a bit lighter compared to boom truck cranes. The crane arm is designed to allow more payloads to be lifted on the back of the mounted vehicle. Most knuckle boom cranes are mounted at the rear of the cab. This leaves the entire bed of the truck empty.
Smaller types of knuckle boom cranes could be utilized without a licensed crane operator, if the load capacity of the machine 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 usually different. Some could control from the ground, radio remote control, stand up and seated control. The radio remote systems could run the crane and starting it. Additionally, many 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 perform tasks at elevated heights. These lifts are lightweight, portable, inexpensive work platforms made to be used indoor. The patented Girder Lock mast design by Snorkel provides superb flexibility and excellent reach. This system, utilized in the UL Series, provides excellent lift capacity.
Snorkel's UL Series Personnel and PAM Series lifts are made so that only one individual is needed to operate the equipment. These machinery are easy to transport. They can easily pass through a standard sized doorway and be pushed smoothly into position. These lifts can be erected in minutes and being able to provide working heights of up to 46 feet, they really are an effective alternative to scaffold towers.
