A knuckle boom crane looks like a regular crane. The key difference is that the boom is capable of folding back like a finger because the boom articulates at the "knuckle" near the center. This enables the equipment to be able to transform into a compact size for maneuvering and storage.
Knuckle boom crane arms are somewhat a bit lighter compared to boom truck cranes. These crane arms are made to allow more payloads to be lifted on the back of the vehicle it is mounted on. Nearly all knuckle boom cranes are mounted behind the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes could be utilized without a licensed crane operator, so long as the maximum capacity is less than 15,000 pounds or if the maximum boom length is less than 25 feet long.
There are various types of control systems for the cranes. For instance, there is radio remote control, control from the ground, seated and stand up control. The radio remote systems could run the crane and starting it. Furthermore, many models come equipped 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, utilized in the UL Series, provides excellent 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 machinery are easy to transport. 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 can provide working heights of up to 46 feet, they truly are an effective alternative to scaffold towers.
