A knuckle boom crane looks like a regular crane. The main distinction is that the boom can fold 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.
Normally, the arm on a knuckle boom crane is quite a bit lighter than boom truck cranes. The crane arm is designed to enable more payloads to be carried 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 models of knuckle boom cranes can be used without a licensed crane operator, if the load capacity of the machinery is less than 15,000 pounds or if the boom's maximum length is less than 25 feet long.
There are various kinds of control systems for the cranes. Like for example, there is radio remote control, control from the ground, stand up and seated control. The radio remote systems could run the crane and starting it. Furthermore, numerous models come equipped with a computer readout system which provides system readouts immediately reporting if the crane is overloaded or not.
Personnel Lifts
Personnel lifts designed by Snorkel have been made to help contractors and maintenance professionals perform tasks at elevated heights. These lifts are inexpensive, lightweight, portable work platforms made to be used indoor. The patented Girder Lock mast design by Snorkel delivers superb flexibility and excellent reach. This system, utilized in the UL Series, provides great 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 machines could be transported easily. They could easily pass through a regular sized doorway and be pushed smoothly into position. These lifts can be erected in minutes and can provide working heights of up to 46 feet, they truly are an effective option to scaffold towers.
