A knuckle boom crane looks similar to a standard crane. The key distinction is that the boom could fold back like a finger because the boom articulates at the "knuckle" near the center. This allows the equipment to be able to transform into a compact size for storage and maneuvering.
Typically, the arm on a knuckle boom crane is quite a little lighter than 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 at the rear of the cab. This leaves the whole bed of the truck empty.
Smaller types of knuckle boom cranes can 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 kinds 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 are capable of running the crane and starting it. Moreover, lots of models come outfitted 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 jobs at elevated heights. These lifts are portable, inexpensive, lightweight 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.
Snorkel's UL Series Personnel and PAM Series lifts are made so that just one person is required to operate the machines. These machines are easy to transport. They could easily pass through a regular sized doorway and be pushed into position smoothly. These lifts are capable of being erected in minutes and being able to provide working heights of up to 46 feet, they are an efficient alternative to scaffold towers.
