Ladder set (10) for hoisting rescue vehicles with a plurality of telescopically extendable ladder parts, including a base part (12) mounted on a vehicle, an end part (18) and a number of connecting parts (14,16) disposed inbetween, an extension cable (22) for extending ladder parts (12,14,16,18), a traction device (28) mounted in the region of base part (12) for extension cable (22) and a roller arrangement for guiding the cable, with roller pairs (32,34) mounted on connecting parts (14,16), of which each front roller (36,38) of pairs (32,34) is disposed on the end of a connecting part (14,16) pointing in the direction of extension, and a rear roller (40, 42) of pairs (32,34) is disposed on the opposite end of this connecting part (14,16), and a deflecting roller (44) on the end of base part (12) pointing in the direction of extension, via which extension cable (22) is guided in the direction of the traction device (28), characterised in that extension cable (22) is secured to end part (18) by its end opposite traction device (28) and is guided from fixation point (30) to deflecting roller (44) then via roller pairs (32,34) of connecting parts (14,16) in their connecting order, in such a way that extension cable (22) first passes the first (36,38) and then the rear rollers (40,42) of a pair (32, 34).
