The knuckle boom crane is somewhat like a typical crane with one key difference. The boom could fold back like a finger. In essence, the boom articulates at the "knuckle" near the middle. This allows the machine to be able to transform into a compact size for storage and maneuvering.
Typically, the arm on a knuckle boom crane is quite a bit lighter compared to boom truck cranes. The crane arm is designed to allow 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.
Interestingly enough, smaller types of knuckle boom cranes could be utilized without a certified crane operator, as long as the maximum capacity is less than 15,000 lbs. or if the maximum boom length is less than 25 feet long.
Control systems for these cranes are normally 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. In addition, numerous models come equipped with a computer readout system that immediately provides system readouts reporting if the crane is overloaded or not.

Personnel lifts designed by Snorkel have been made to help contractors and maintenance professionals carry out tasks at elevated heights. These lifts are affordable, lightweight, portable work platforms made for interior use. The patented Girder Lock mast design by Snorkel provides excellent reach and superb stability. This system, utilized in the UL Series, offers great lift capacity.
The Snorkel UL Series Personnel and PAM Series lifts have been built and designed in order to be easy for one individual to operate. These machines can be transported easily. They could easily pass through a standard 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 effective alternative to scaffold towers.
