The knuckle boom crane is quite like a regular crane with one key distinction. The boom can fold back similar to a finger. In essence, the boom articulates at the "knuckle" near the middle. This allows 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 little lighter than boom truck cranes. The crane arm is designed to allow more payloads to be lifted on the back of the mounted vehicle. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the whole bed of the truck empty.
Smaller types of knuckle boom cranes can be used without a licensed crane operator, if the load capacity of the equipment is less than 15,000 pounds or if the boom's maximum length is less than 25 feet long.
Control systems for these cranes are often different. Some can control from the ground, radio remote control, stand up and seated control. The radio remote systems are capable of running the crane and starting it. Furthermore, numerous models come equipped with a computer readout system that 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 portable, inexpensive, lightweight work platforms made to be used indoor. 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.
The Snorkel UL Series Personnel and PAM Series lifts have been built and designed in order to be easy for one person to operate. These equipment are easy to transport. They can 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 efficient option to scaffold towers.
