A knuckle boom crane looks like a typical crane. The main distinction is that the boom can fold back like a finger since the boom articulates at the "knuckle" near the center. This allows the machinery to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are somewhat a little lighter than boom truck cranes. These crane arms are made to enable more payloads to be carried on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted at the rear of the cab. This leaves the entire bed of the truck empty.
Smaller types of knuckle boom cranes could be utilized without a certified crane operator, if the load capacity of the equipment is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
There are various types of control systems for the cranes. Like for instance, there is radio remote control, control from the ground, seated and stand up control. The radio remote systems could run the crane as well as starting it. Moreover, numerous models come outfitted 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 portable, inexpensive, lightweight work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers superb flexibility and excellent reach. This system, utilized in the UL Series, provides excellent lift capacity.
Snorkel's PAM Series and UL Series Personnel lifts are made so that only one individual is needed to operate the machines. These machinery could be transported easily. They can easily pass through a standard sized doorway and be pushed into position smoothly. These lifts could be erected in minutes and could provide working heights of up to 46 feet, they are an effective alternative to scaffold towers.
