Disclosed is a hoisting system (10) for hoisting a vertically-suspended object (50), the hoisting system (10) having a winch (20) having a winch drum (21) with a hoisting rope (25), wherein a first part (25-1) of the hoisting rope (25) has a first diameter (d1) and a second part (25-2) has a second diameter (d2) being larger than the first diameter (d1), the first part (25-1) being connected with a first end (25fe) of the second part (25-2), wherein the first part (25-1) is an inner part (20i) on the winch drum (21) when the winch drum (21) is completely wound, wherein the second part (25-2) has a further end (25se) that is connectable to the object (50) for hoisting the object (50), wherein a ratio between the first diameter (d1) and the second diameter (d2) is chosen such that the minimum breakable load of the first part (25-1) differs less than a factor of four from the minimum breakable load of the second part (25-2), and preferably less than a factor of three. Further disclosed is a method for hoisting a vertically-suspended object (50) with such hoisting system (10) and a winch (20) for such hoisting system (10). A much more compact and less-costly hoisting system is thereby obtained.
