The knuckle boom crane is quite similar to a standard crane with one key distinction. The boom can fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machine 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 than boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Most knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller models of knuckle boom cranes are capable of being utilized without a certified crane operator, so long as the maximum capacity is less than 15,000 pounds or if the maximum boom length is less than 25 feet long.
Control systems for these cranes are normally 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 and starting it. Moreover, numerous models come outfitted with a computer readout system which immediately 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 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 excellent reach and superb stability. This system, used in the UL Series, provides excellent lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that only one person is required to operate the equipment. These equipment can be transported easily. They could easily be pushed into position smoothly and pass through a standard sized doorway. These lifts are capable of being erected in minutes and could provide working heights of up to 46 feet, they are an efficient alternative to scaffold towers.
