The knuckle boom crane is somewhat similar to a regular crane with one key difference. The boom is capable of folding back like a finger. In essence, the boom articulates at the "knuckle" near the middle. This allows the machinery to be able to transform into a compact size for storage and maneuvering.
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 behind the cab. This leaves the entire bed of the truck empty.
Interestingly enough, smaller models of knuckle boom cranes are capable of being used without a licensed crane operator, as long as the maximum capacity is less than 15,000 pounds or if the maximum boom 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 operate the crane and starting it. Additionally, numerous models come equipped with a computer readout system that immediately 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 perform 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 delivers excellent reach and superb stability. This system, used in the UL Series, offers excellent lift capacity.
Snorkel's UL Series Personnel and PAM Series lifts are made so that only one person is required to operate the equipment. These machinery could be transported easily. They can easily pass through a standard sized doorway and be pushed smoothly into position. These lifts can be erected in minutes and being able to provide working heights of up to 46 feet, they are an efficient option to scaffold towers.
