The Tanner Hill Estate is a public housing estate dedicated to elderly people in the immediate vicinity of the city centre of Hong Kong. A curved SafeAccess rail enables a traversing SafeLadder to roll along the façade. The ladder is equipped with footrests and an integrated fall arrest rail for the highest level of safety. The traversing SafeLadder is a good choice for fragile facades or green walls that can’t support pressure points on all the surface.
