The HiViz Lift Shaft Tower conforms to BS.EN. 1004 European Standard. Built with the 3T (Through the Trapdoor) method the lift shaft tower is a great working at height solution for a confined space problem, such as a lift shaft. The tower has a wide range of heights available reaching up to 30.95m in platform height. By using our standard single width ladder frames, you can utilise your existing current stock. For optimum stability we have created specialized Lift Shaft Tower Props to help stabilize the tower while in the lift shaft.
