Calculate minimum crane wheel diameter.
Permissible pressure coefficient
$$ c_1 = 0.5 \:
$$
Speed coefficient
$$ c_2 = 1.09 \:
$$
Operating time coefficient
$$ c_3 = 1.25 \:
$$
Effective rail width
$$ w_{rail_{ef}} = 65 \:
mm $$
Minimum wheel diameter
$$ D_{wheel_{min}} = {{R_{wheel_{mean}} \over \left({ 5.6 \cdot c_1 \cdot c_2 \cdot c_3 \cdot w_{rail_{ef}} }\right)}} \:, mm $$
