Aluminum fire ladder, 4 m, 6 m, 9 m, 12 m, 15 m of four specifications. 


 Three TSL aluminum alloy pull the ladder, three in the previous section ladder into the middle ladder, mid-level ladder into the lower-level ladder, and the pressure angle limit. On the side panel of the intermediate ladder, slide the bottom of the side panels of the previous section ladder is equipped with guides to facilitate the lifting of the ladder to prevent skew the composition of the lifting devices of the three ladders from the pulley, rope and stop the axis
