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 equipment to be able to transform into a compact size for maneuvering and storage.
Normally, the arm on a knuckle boom crane is somewhat a little lighter than 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.
Smaller types of knuckle boom cranes could be used without a licensed crane operator, if the load capacity of the machinery is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
There are different types 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 run the crane and starting it. In addition, numerous models come outfitted 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 perform jobs at elevated heights. These lifts are lightweight, portable, inexpensive work platforms made to be utilized indoor. The patented Girder Lock mast design by Snorkel delivers excellent reach and superb stability. This system, used in the UL Series, offers great lift capacity.
The Snorkel UL Series Personnel and PAM Series lifts have been built and designed so as to be easy for one individual to utilize. These equipment can be transported easily. They could easily pass through a standard sized doorway and be pushed smoothly into position. These lifts are capable of being erected in minutes and could provide working heights of up to 46 feet, they are an efficient alternative to scaffold towers.
