A knuckle boom crane looks like a regular crane. The key distinction is that the boom could fold back similar to a finger since the boom articulates at the "knuckle" near the middle. 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 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 behind the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes can be used without a licensed 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 usually different. Some can control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane and starting it. Additionally, a lot of models come equipped 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 maintenance professionals and contractors carry out tasks at elevated heights. These lifts are inexpensive, lightweight, portable work platforms made to be utilized indoor. 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.
The Snorkel UL Series Personnel and PAM Series lifts have been designed and built so as to be easy for one individual to use. These machinery can be transported easily. They could easily pass through a standard sized doorway and be pushed smoothly into position. These lifts can be erected in minutes and could provide working heights of up to 46 feet, they truly are an efficient alternative to scaffold towers.
