The knuckle boom crane is somewhat like a regular crane with one key distinction. The boom could fold back like a finger. In essence, the boom articulates at the "knuckle" near the middle. This enables the machine to be able to transform into a compact size for maneuvering and storage.
Normally, the arm on a knuckle boom crane is somewhat a bit 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. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the whole bed of the truck empty.
Smaller kinds of knuckle boom cranes can be utilized without a licensed crane operator, if the load capacity of the machine is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
There are different kinds of control systems for the cranes. For example, there is radio remote control, control from the ground, seated and stand up control. The radio remote systems are capable of running the crane and starting it. Furthermore, 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 tasks at elevated heights. These lifts are affordable, lightweight, portable work platforms made to be used indoor. The patented Girder Lock mast design by Snorkel delivers excellent reach and superb stability. This system, used in the UL Series, provides great lift capacity.
Snorkel's UL Series Personnel and PAM Series lifts are made so that only one person is needed to operate the machines. These machines can be transported easily. They could easily pass through a regular sized doorway and be pushed smoothly into position. These lifts are capable of being erected in minutes and being able to provide working heights of up to 46 feet, they are an effective option to scaffold towers.
