A knuckle boom crane looks like a regular crane. The key distinction is that the boom is capable of folding back like a finger as 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.
Typically, the arm on a knuckle boom crane is quite a little lighter compared to 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 at the rear of the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller types of knuckle boom cranes can be used without a certified 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.
Control systems for these cranes are normally different. Some could control from the ground, radio remote control, stand up and seated control. The radio remote systems can run the crane and starting it. Additionally, many models come equipped with a computer readout system which instantly 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 lightweight, portable, inexpensive work platforms made for interior use. The patented Girder Lock mast design by Snorkel provides excellent reach and superb stability. This system, used in the UL Series, offers excellent lift capacity.
The Snorkel PAM Series and UL Series Personnel lifts have been built and designed in order to be easy for one individual to utilize. These machinery are easy to transport. They can easily be pushed into position smoothly and pass through a regular sized doorway. These lifts are capable of being erected in minutes and can provide working heights of up to 46 feet, they are an efficient option to scaffold towers.
