A knuckle boom crane looks similar to a standard crane. The main distinction is that the boom is capable of folding back like a finger as the boom articulates at the "knuckle" near the middle. This enables 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 little 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 at the back of the cab. This leaves the entire bed of the truck empty.
Smaller kinds of knuckle boom cranes can be used without a licensed 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 example, there is control from the ground, radio remote control, seated and stand up control. The radio remote systems can operate the crane and starting it. Furthermore, a lot of models come equipped with a computer readout system that immediately 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 carry out jobs at elevated heights. These lifts are lightweight, portable, affordable work platforms made for interior use. The patented Girder Lock mast design by Snorkel provides excellent reach and superb stability. This system, used in the UL Series, offers excellent lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that only one individual is required to operate the equipment. These equipment are easy to transport. They can 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 option to scaffold towers.
