A knuckle boom crane looks similar to a standard crane. The key difference is that the boom is capable of folding back like a finger since the boom articulates at the "knuckle" near the middle. This enables the machine to be able to transform into a compact size for maneuvering and storage.
Normally, the arm on a knuckle boom crane is quite a bit lighter than boom truck cranes. The crane arm is designed to allow more payloads to be lifted on the back of the mounted vehicle. Most knuckle boom cranes are mounted at the rear of the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes are capable of being 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 different kinds of control systems for the cranes. 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 and starting it. Moreover, numerous models come outfitted 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 jobs at elevated heights. These lifts are lightweight, portable, affordable work platforms made to be utilized indoor. The patented Girder Lock mast design by Snorkel provides superb flexibility and excellent reach. This system, utilized in the UL Series, offers excellent lift capacity.
The Snorkel UL Series Personnel and PAM Series lifts have been designed and built so as to be easy for one individual to use. These machinery are easy to transport. They can easily be pushed into position smoothly and pass through a regular sized doorway. These lifts can be erected in minutes and being able to provide working heights of up to 46 feet, they truly are an efficient option to scaffold towers.
