Abstract:
The invention relates to a method for replacing the hoisting ropes of an elevator. By the method of the invention, the hoisting ropes (4) are replaced by first joining the old and new hoisting ropes (4a, 4b) together by their one ends by splicing the ends together around a common core strand (17), whereupon the new set (4b) of hoisting ropes is pulled into place by means of the old set (4a) of hoisting ropes.
