Currently, cranes are used as transportation equipment in various industries such as construction, distribution, and manufacturing. Materials and products are transported indoors using overhead cranes and mainly using large crawler cranes at outdoor construction sites. In the construction field, work involving suspended materials and products by attaching multiple lifting tools and chain blocks to a crane hook is called lifting work.Then, the material or product suspended from the crane hook is called a suspended load.Basically, if the product is traveling, the suspended load is moved up, down, left and right by the operation of the crane operator. Conversely, in high and narrow places, the suspended load must be rotated to avoid collision with surrounding interference. However, the crane hook is a free Development of a suspended-load rotation-control device for cranes with gyroscopic damper and control by wind force (concept, modeling and experiments)
