The knuckle boom crane is quite like a typical crane with one main distinction. The boom could fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This enables the equipment to be able to transform into a compact size for storage and maneuvering.
Normally, the arm on a knuckle boom crane is quite a bit lighter compared to boom truck cranes. The crane arm is designed to allow more payloads to be carried on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes are capable of being 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 types of control systems for the cranes. Like for example, there is radio remote control, control from the ground, seated and stand up control. The radio remote systems can run the crane and starting it. In addition, lots of models come outfitted with a computer readout system which 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 tasks 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, used in the UL Series, provides great lift capacity.
Snorkel's UL Series Personnel and PAM Series lifts are made so that only one individual is needed to operate the machines. These machinery could be transported easily. They could easily be pushed into position smoothly and pass through a standard sized doorway. These lifts are capable of being erected in minutes and can provide working heights of up to 46 feet, they truly are an efficient option to scaffold towers.
