Helicopter lifting beams
A helicopter lifting beam is a special type of cross beam with 4 load attachment points, which consists of two spreader beams that can be rotated around a central vertical axis. They are mostly used for boat transportation. As the support arms can rotate freely, the rectangular stop automatically adjusts to the load width (e.g. the boat hull). These lifting beams can also be telescoped. When folded and pushed together, they save space when storage.
