The diameter of rope drum is usually determined by standardized line of diameters for drums and it is dependent on diameter of wound rope. The groove for rope, executed as continuous spiral along the shell, ensures the correct winding of rope to drum, when dimensions of this groove are determined in dependence on rope diameter.
