The roping (R) travels from the aforementioned rope pulley or rope pulley stack (4) down to an elevator unit (1, 2), in connection with which is a first rope pul­ ley or rope pulley stack and a second rope pulley or rope pulley stack, which are dis - posed non- coaxially in relation to each other, their rotation axes being separate from each other in the lateral direction, and in that the first part (a) of the ropes of the rop - ing (R) traveling from the rope pulley or rope pulley stack (4) down to the elevator unit (1, 2) travels, to the elevator unit (1, 2), to the first rope pulley or rope pulley stack that is in connection with the elevator unit (1, 2), under the pulley or stack, and onwards back up to a rope anchorage arrangement, and the second part (b) to the second rope pulley or rope pulley stack in that is, connection with the elevator unit in question, under the pulley or stack, and onwards back up to rope a anchorage arrange­ ment. The invention also relates to corresponding guidance of compensating roping, as well as to a method wherein the service range of the elevator car is increased. i-H o CJ o & WO 2013/175054 A11 lllll llllllll II llllll III lllll lllll lllll lllll III III III lllll lllll lllll llll llll lllllll llll llll u ls e ' — before the expiration of the time limit for amending the — with international search report (Art. 21(3)) claims and to be republished in the event of receipt of amendments (Rule 48.2(h))
