Dokumentation des Hauptaltares


Ziel der Arbeiten war die Untersuchung und Dokumentation vom Zustand und der Schäden an den polychromen Figuren und Verzierungen des Hauptaltares im Kloster Bronnbach.


Hier war die Höhe mit 16 Metern deutlich geringer als bei anderen Projekten, die  Möglichkeit des PHOTOLIFTER, eine Kamera unmittelbar unter die Decke zu bringen, stand hier im Vordergrund.

Der ruhige Schwebezustand des PHOTOLIFTER ermöglichte es dabei, den Figuren sehr nahe zu kommen und gefährliche Luftbewegungen - und somit auch das Aufwirbeln von Stäuben - sicher

zu vermeiden.

Monastery BRONNBACH - Main Altar


August 2019 we had the chance to monitor and photograph the main altar of the Bronnbach Monastery in Baden Wuerttemberg, Germany. Here you read about the operating procedure, the necessity to apply a special technical construction - and the realization with our adaptive aerial system PHOTOLIFTER. Please enjoy the close look at beautiful historical artwork from 1712.


The target of this project was the disturbance-free, fast as cost-efficient monitoring and documentation of the actual status, detecting unknown damages and hidden details, which are not visible from the ground. The 15 meters hight of the Bronnbach alter were just a quarter of the altitude the PHOTOLIFTER had been operated before - but not less demanding.

The Bronnbach altar´s close proximity to the ceiling draw a special technical demand.

It required the highest possible camera position that only expensive and disturbing scaffolding could have enabled - there is just a hand between the top end of the alter

and the arched ceiling.

Drones fail here in multiple ways. First of all, the authorities ban free-flying objects

from sensible historic buildings, due to their potential danger - proven costly several times before. Secondly, due to the need for free air movement, drones have to keep a safe distance to walls, obstacles, and especially the ceiling. Fatal, as their general disruption of unavoidable air turbulences that create a long-lasting fall-out of disturbing and often pollutant dust.

The aerial systems we develop, build and operate

on location are customized

and adaptive prototypes.

They are no free-flying

blimps, helicopters, drones

or comparable loose flying obstacles. They do not have rotating parts or any other element, which cause a hazardous situation or create irritating turbulences.


Our patented LIFTERs remain connected to the ground, tread- and steering strings provide a calm and steady hovering position to work scientifically in calm accuracy.

For the photographs, taken so close to the ceiling, our cameras were attached above the balloons and leveled horizontally. As the top end of a high interior room is always full of air movement we had to upgrade the positioning system for the balloons to reach the necessary calm poise. Especially the high-resolution cameras respond sensible to any motion, as the dense pixel pattern intends to deliver immediately unsharp photos.

At altars only the highest possible camera position enables to capture the actual degree

of partial damage. In this case the camera had to be positioned just below the ceiling.

A working group of our customer - the Landesamt für Denkmalpflege of Baden Wuerttemberg - followed the camera view from the ground. In real-time, they led

us to the specific details they were looking for. Please ask for original photographs to illustrate the high resolution and the amount of details.


We gained a lot of experience that exciting day - as a very satisfying result.
