The Genesis Shaftway Model fits inside a vertical runway (also known as a hoistway or shaftway) that is built by others in accordance to Garaventa Lift specifications. This vertical platform lift consists of a drive mast, passenger platform, doors and gates. The hoistway at the uppermost landing can be protected by a gate and surrounding hoistway walls that are only 42″ tall. Another alternative is to put a full height door (80″ tall) on the lift entrance and extend the surrounding walls to the ceiling. In cases where children or teens may be frequenting the area, it is advisable to enclose the uppermost landing completely, even if this exceeds minimum code requirements.
