The knuckle boom crane is quite similar to a standard crane with one main difference. The boom can fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the center. This allows the machine to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are somewhat a little lighter than 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 entire bed of the truck empty.
Interestingly enough, smaller models of knuckle boom cranes could be utilized without a licensed 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 different types of control systems for the cranes. For instance, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems can operate the crane and starting it. Additionally, a lot of models come equipped with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.

Snorkel Personnel Lifts are designed for facilities maintenance professionals and contractors. These lifts are portable, inexpensive, lightweight work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers superb flexibility and excellent reach. This system, utilized in the UL Series, provides excellent lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that only one individual is required to operate the machines. These machines could be transported easily. They could easily pass through a standard sized doorway and be pushed into position smoothly. These lifts could be erected in minutes and being able to provide working heights of up to 46 feet, they truly are an effective alternative to scaffold towers.
