The knuckle boom crane is quite similar to a regular crane with one main distinction. The boom is capable of folding back like 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 storage and maneuvering.
Normally, the arm on a knuckle boom crane is somewhat 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. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes could be used without a certified crane operator, as long as the maximum capacity is less than 15,000 lbs. or if the maximum boom length is less than 25 feet long.
There are various types of control systems for the cranes. For example, there is control from the ground, radio remote control, stand up and seated control. The radio remote systems can operate the crane as well as starting it. Additionally, numerous models come equipped with a computer readout system that 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 jobs at elevated heights. These lifts are portable, inexpensive, lightweight work platforms made for interior use. The patented Girder Lock mast design by Snorkel provides excellent reach and superb stability. This system, utilized 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 machines. These equipment are easy to transport. They could easily pass through a regular sized doorway and be pushed into position smoothly. These lifts can be erected in minutes and being able to provide working heights of up to 46 feet, they are an efficient option to scaffold towers.
