A knuckle boom crane looks similar to a regular crane. The main distinction is that the boom could fold back like a finger because the boom articulates at the "knuckle" near the center. This allows the equipment to be able to transform into a compact size for storage and maneuvering.
Usually, the arm on a knuckle boom crane is quite a little lighter compared to 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 rear of the cab. This leaves the entire bed of the truck empty.
Smaller kinds of knuckle boom cranes could be utilized without a certified 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.
Control systems for these cranes are usually different. Some could control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane as well as starting it. In addition, 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 maintenance professionals and contractors perform jobs at elevated heights. These lifts are lightweight, portable, inexpensive work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers excellent reach and superb stability. 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 required to operate the machines. These machinery can be transported easily. They could easily pass through a standard sized doorway and be pushed smoothly into position. These lifts could be erected in minutes and being able to provide working heights of up to 46 feet, they are an efficient option to scaffold towers.
