[0060] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.
[0061] The present invention is applicable to the straight-arm type rescue and wrecker vehicle 1 working on horizontal roads, and does not consider the influence of special weather conditions such as strong wind and rainfall on the rescue and wrecker vehicle 1, and ignores the rotation of the earth. And make the following reasonable assumptions: during the operation of the rescue wrecker 1 boom 3, the rope 5 is stretched straight, the plane where the rope 5 and the boom 3 are located is perpendicular to the horizontal plane, and the distance between the boom 3, the rope 5 and the hook 8 is perpendicular to the horizontal plane. Movement is slow and can be considered stationary for short periods of time.
[0062] Such as figure 1 As shown, a kind of rescue wrecker boom overload early warning method of ...
