The knuckle boom crane is quite like a standard crane with one main difference. The boom could fold back like a finger. In essence, the boom articulates at the "knuckle" near the middle. This allows the machinery to be able to transform into a compact size for maneuvering and storage.
Knuckle boom crane arms are quite a little lighter compared to boom truck cranes. These crane arms are made to allow more payloads to be carried on the back of the vehicle it is mounted on. 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 could be utilized without a licensed crane operator, as 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 instance, there is control from the ground, radio remote control, seated and stand up control. The radio remote systems could operate the crane and starting it. Furthermore, lots of models come outfitted 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 maintenance professionals and contractors carry out tasks at elevated heights. These lifts are portable, inexpensive, lightweight work platforms made to be used indoor. 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 PAM Series and UL Series Personnel lifts are made so that only one individual is required to operate the equipment. These machines could be transported easily. They could easily pass through a standard sized doorway and be pushed smoothly into position. These lifts could be erected in minutes and could provide working heights of up to 46 feet, they are an effective option to scaffold towers.
