The knuckle boom crane is somewhat similar to a standard crane with one key distinction. The boom could fold back similar to 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 maneuvering and storage.
Knuckle boom crane arms are somewhat a little lighter compared to boom truck cranes. These crane arms are made to enable more payloads to be lifted 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.
Interestingly enough, smaller kinds of knuckle boom cranes can 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.
There are various kinds of control systems for the cranes. For instance, there is control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane as well as starting it. Additionally, a lot of models come equipped with a computer readout system that 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 perform tasks at elevated heights. These lifts are portable, affordable, 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 PAM Series and UL Series Personnel lifts are made so that just one person is required to operate the machines. These machinery are easy to transport. They could easily pass through a standard sized doorway and be pushed into position smoothly. 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.
