The knuckle boom crane is somewhat like a standard crane with one key difference. 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.
Knuckle boom crane arms are somewhat a little lighter compared to boom truck cranes. These crane arms are made to allow more payloads to be carried on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted at the rear of the cab. This leaves the whole bed of the truck empty.
Smaller kinds of knuckle boom cranes could be used without a certified crane operator, if the load capacity of the machinery is less than 15,000 pounds or if the boom's maximum length is less than 25 feet long.
There are various types of control systems for the cranes. Like for instance, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems can operate the crane as well as starting it. In addition, a lot 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 portable, inexpensive, lightweight work platforms made for interior use. The patented Girder Lock mast design by Snorkel provides superb flexibility and excellent reach. This system, utilized in the UL Series, provides excellent lift capacity.
The Snorkel UL Series Personnel and PAM Series lifts have been built and designed so as to be easy for one individual to operate. These machines are easy to transport. They can easily pass through a regular 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 are an effective option to scaffold towers.
