The knuckle boom crane is somewhat like a standard crane with one key distinction. The boom could fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machinery to be able to transform into a compact size for maneuvering and storage.
Typically, the arm on a knuckle boom crane is somewhat a bit lighter than 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 entire bed of the truck empty.
Interestingly enough, smaller models of knuckle boom cranes are capable of being utilized without a licensed crane operator, so long as the maximum capacity is less than 15,000 lbs. or if the maximum boom 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 are capable of running the crane as well as starting it. Additionally, numerous models come equipped with a computer readout system which instantly 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 lightweight, portable, inexpensive work platforms made to be utilized indoor. 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 can be transported easily. They could easily be pushed into position smoothly and pass through a standard sized doorway. These lifts can be erected in minutes and being able to provide working heights of up to 46 feet, they truly are an effective alternative to scaffold towers.
