A knuckle boom crane looks like a regular crane. The key distinction is that the boom is capable of folding back like a finger since the boom articulates at the "knuckle" near the middle. This allows the equipment to be able to transform into a compact size for maneuvering and storage.
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 at the rear of the cab. This leaves the whole bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes are capable of being used without a certified crane operator, as 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 different kinds 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 are capable of running the crane as well as starting it. In addition, numerous models come outfitted with a computer readout system that provides system readouts at once reporting if the crane is overloaded or not.

Personnel lifts designed by Snorkel have been made to help contractors and maintenance professionals carry out tasks 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 superb flexibility and excellent reach. This system, utilized in the UL Series, offers excellent lift capacity.
The Snorkel PAM Series and UL Series Personnel lifts have been designed and built so as to be easy for one person to use. These equipment are easy to transport. They could easily be pushed into position smoothly and pass through a regular sized doorway. These lifts are capable of being erected in minutes and could provide working heights of up to 46 feet, they truly are an effective alternative to scaffold towers.
