PURPOSE:To contrive to secure safety in a testing operation, by using an anchor chain as a load for testing. CONSTITUTION:When loading a cargo, a length of the anchor chain 2 is suspended from a crane, and is gradually bottomed starting from the lower end thereof while lowering a hook 1. Accordingly, even in the case of a roofed boat 11, the chain 2 can be dropped to the bottom 5 of the boat 11 through an entrance 11a. When using the anchor chain 2 as a load, the shape of the load is flexible, and can easily conform to the shape of the place where the load is placed, so that the load can be placed on the floor of the boat 11 while uniformly distributing it. |
