BesonderheitenSpecial features outdoor glass elevator at a lighthouse, backpack suspension of the cabin counterweight not visibly covered, all steel parts hot-dip galvanized or V4A powder coated, cabin tight against rain, special measures due to exceeding of the conveyance height

Weber had already planned a small hotel in the disused Großer Vogel­sand light­house in the Deut­sche Bucht in 2003 and was thrilled by the view from there. With the very open loca­tion on the Baaken­höft point, the entre­pre­neur chose a very exclu­sive loca­tion for the Lighthouse.

Such an unusual buil­ding also had to be equipped with an extra­or­di­nary, free-running elevator, which is why we, as a specia­list manu­fac­turer of special systems, were chosen. Econo­mic­ally, the extra­va­gant order was diffi­cult to calcu­late. However, for Thoma the focus was not on busi­ness, but on the oppor­tu­nity to design and build an inno­va­tive, unique elevator system to match the building. 

Running a system outdoors is always tech­ni­cally much more complex. In the port of Hamburg, however, wind, rain and salty sea air are addi­tional factors. All compon­ents were ther­e­fore to be either hot-dip galva­nized or made of V4A stain­less steel to protect them from the risk of corro­sion. Where possible, the tech­no­logy was to disap­pear behind large-area clad­ding for archi­tec­tural reasons. We had already sealed the cabins at our plant in Frank­furt, trans­ported them “in one piece” and mounted them comple­tely prefa­bri­cated on the frame.

The eleva­tor’s height of 20 meters with only two stops presented a further diffi­culty: In the event of a possible malfunc­tion, where the elevator stops between the stops, an “emer­gency exit door” is normally prescribed for rescuing people. However, this was not desired for aesthetic reasons and would probably have been of only limited help in prac­tice. We ther­e­fore had to agree on an alter­na­tive safety concept with the TÜV expert.
