The invention provides a tension test device and a tension test method thereof.The tension test device comprises a floating crane, a stable hook and/or a stable cargo winch and at least two sets of securing and redirection devices, the stable hook and/or the stable cargo winch are/is installed on the floating crane, and the securing and redirection devices are fixed to a ship deck; and the fastening redirection device is connected with a first steel wire rope, is in butt joint with two winding steel wire ropes of the stable hook and/or the stable cargo winch, and is connected with the winding steel wire ropes into a whole to form a closed loop, so that a tension test is carried out by a closed-loop opposite pulling method of the stable hook and/or the stable cargo winch. According to the invention, two groups of fastening redirection devices are arranged on a ship body, two winding steel wire ropes for stabilizing hooks or goods are connected into a whole to form a closed loop, and a tension experiment is carried out by using a closed-loop opposite-pulling method of a stable hook or a stable goods winch. Meanwhile, the head of the connecting steel wire rope is connected with the dynamometer for displaying the tension value of the tension test in real time, so that the tension value is controllable.

本发明提供了一种拉力试验装置及其拉力试验方法，拉力试验装置包括浮动起重机、稳钩和/或稳货绞车和至少两组系固改向装置，所述稳钩和/或稳货绞车安装在所述浮动起重机上，所述系固改向装置固定在船体甲板上；所述系固改向装置连接第一钢丝绳与所述稳钩和/或稳货绞车的两根缠绕钢丝绳对接，和所述缠绕钢丝绳连接为整根形成闭环，用于所述稳钩和/或稳货绞车闭环对拉的方法进行拉力试验。本发明通过在船体上安装两组系固改向装置，将稳钩或稳货的两根缠绕钢丝绳连接为整根形成闭环，用稳钩或稳货绞车闭环对拉的方法进行拉力实验。同时在连接钢丝绳绳头连接测力计，用于实时显示拉力试验的拉力值，保证拉力值可控。
