Lift for building work - has pre-assembled shaft with cabin of cast parts and has manual operation if power fails

摘要

The lift has a pre-assembled shaft. This allows interior or exterior mounting for building work. The cabin is made up partially of castings. The lift is power driven, the power assembly being of reduced height. The drive uses driven gullies and an idler at the top. The shaft has sliding bearings between which the cabin moves. In case of failure, a manure drive can be used from inside the cabin to lower to base.
