The invention discloses a determination method for a structural parameter of a moment limiter of a bent board matched with a tower crane and relates to a moment limiter of a tower crane for displaying the load moment in real time so as to pre-warn overload. The determination method particularly aims at a double-hanging-point upper rotary tower crane. The determination method aims at solving the problem that the precision is not high and the sensitivity is relatively low due to insufficient deflection variation because of ubiquitous insufficiency of magnifying power of the existing moment limiter of the bent board. The determination method is used for deducing specific analysis formulae of the magnifying power and the deflection by virtue of a mechanics analysis method and an analytical method, and a mathematical model that the moment limiter of the bent board is matched with the tower crane is established, so that the tower crane is matched with the structural parameter of the moment limiter of the bent board. The determination method disclosed by the invention has theoretical and application values in designing the moment limiter of the bent board and improving the sensitivity. After the model number of the tower crane is determined and the moment limiter of the bent board is initially selected, whether the magnifying power and the deflection meet the using demand or not is calculated by the determination method, so that the structural parameter of the moment limiter of the bent board is optimized and matched.
