Turning effects of forces — practice question

The diagram illustrates a crane carrying a load $L$. A mass acts as a balancing load $W$. The load is positioned so that the system is exactly in equilibrium, with $Wx = Ly$. The ground exerts a reaction force $R$. The distance $x$ stays unchanged. If the load is moved further away so that the distance $y$ becomes larger and the crane does not topple, which statement is correct?
