The Research On New Crane Rail-Clamp Anchor Used In Ship-making And Ship-repairing

A rail-clamp anchor is the necessary unit that provides security guarantee against strong wind for crane, especially for those used in ship-making and ship-repairing field, which usually are located at seashore and which often are subjected to typhoons, cyclone or flurry. When they are attacked by these kinds of strong winds without the protection of reliable anchors to fix them with the rails, the cranes would run along the rails out of control and lead to definitely economic and life lost. It has been proposed significantly in the crane security stipulation that cranes working outside, especially being located at seashore, which is subjected to the greater wind-load, have to fix a rail-clamp anchor.Based on a series investigation and analysis, and on the real requirement of the author's department---a harbor, the author gives a compare in detail between different schemes, choose tow of them to design with traditional methods, and present a manual operated rail-clamp anchor and an electrical driven one. The parameters and the structures of the anchor are aimed at the real requirement. The designed rail-clamp anchors have a better performance, such as enabling to adjust their anchor_force following wind_load and having the self-lock ability.Some expectations of research are proposed for future.
