A knuckle boom crane looks like a typical crane. The key difference is that the boom can fold back like a finger since the boom articulates at the "knuckle" near the center. This enables the equipment to be able to transform into a compact size for maneuvering and storage.
Knuckle boom crane arms are somewhat a little lighter compared to boom truck cranes. These crane arms are made to allow more payloads to be carried on the back of the vehicle it is mounted on. Nearly all knuckle boom cranes are mounted at the back of the cab. This leaves the whole bed of the truck empty.
Smaller kinds of knuckle boom cranes could be utilized 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 usually different. Some could control from the ground, radio remote control, stand up and seated control. The radio remote systems could operate the crane and starting it. Furthermore, many models come equipped with a computer readout system that 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 lightweight, portable, affordable work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers superb flexibility and excellent reach. This system, used in the UL Series, offers great lift capacity.
The Snorkel PAM Series and UL Series Personnel lifts have been built and designed so as to be easy for one individual to operate. These equipment are easy to transport. They could easily pass through a regular sized doorway and be pushed smoothly into position. These lifts are capable of being erected in minutes and can provide working heights of up to 46 feet, they truly are an efficient alternative to scaffold towers.
