In Low Headroom models, the C-dimension depends on the wheel-gauge of the trolley!
When the B-dimension increases, the fleet angle of the ropes with the hook in the upmost position
changes accordingly. To avoid overloading the ropes, overload device, return sheaves and other
structures, the minimum C-dimension may not be smaller than the dimensions as below.
