The knuckle boom crane is somewhat like a typical crane with one main difference. The boom can fold back like 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.
Knuckle boom crane arms are quite a little lighter compared to boom truck cranes. These crane arms are made to enable more payloads to be carried on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted behind the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller models of knuckle boom cranes could be utilized without a certified 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 can control from the ground, radio remote control, seated and stand up control. The radio remote systems could run the crane as well as starting it. Moreover, lots of models come equipped with a computer readout system which 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 contractors and maintenance professionals carry out jobs at elevated heights. These lifts are inexpensive, lightweight, portable work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers excellent reach and superb stability. This system, utilized in the UL Series, provides great lift capacity.
The Snorkel UL Series Personnel and PAM Series lifts have been built and designed in order to be easy for one individual to utilize. These machinery could be transported easily. They could easily be pushed smoothly into position and pass through a regular sized doorway. These lifts could be erected in minutes and could provide working heights of up to 46 feet, they are an efficient option to scaffold towers.
