1. Application

Millions of square meters of facade await renewal each year. Either the general state of the building demands urgent renovation, or echologially and economically practical insulation is lacking. A study stated about 75 million square meters of surface in urgent need of restoration in the new German states.
Additionally the cleaning and the preparation of thecnical surfaces, e.g. ships, tanks, has to be done.

2. Outline

The BIBER System consists of three components:
toolhead, a telescoping manned platform or another lifting unit, and a vacuum cleaner.

The toolhead is the most innovative part of the whole system. The principal application is the removal of roughcast or other old coating by means of a brush. For other areas - the scrubbing of brushing of large surfaces - appropriate applications are being developed. It is the attachment - and drive-housing for rapidly rotating tools, such as mills, brushes and cylinders.

A telescoping manned platform is the key to the optimal application of the system. In no time the work platform can be replaced by the BIBER System toolhead. The telescoping lift offers innumerable use, for example wherever and whenever a lack of space (or money) prevents the erection of scaffolding. Small repairs can be carried out, even at tremendous heights.

The vacuum opening is located behind the drive housing. The vacuum "swallows" the particles loosened from the treated surface, passing them through its hoses to a receptacle. The air is then filtered, and the remaining refuse divided among designated containers. The vacuum cleaner is also specially designed for the cleaning of large surfaces. Furthermore, it supports the logistics at the construction site by its ability to move large quantities of various building materials.
All components of BIBER System can be used independently of another. Backhoes, for example,
through the use of an adapter, can assume the guide function for the toolhead.

3. Characteristics and effects
  1. Removal, cleaning or preparation can be preformed with an accuracy higher than provided by skilled worker; moreover a uniform surface can be expected.
  2. Conventional manual work is reduced to a minimum, so the worker is relieved from the burden of hard and dusty work in uncomfortable positions.
  3. Work efficiency can be improved
  4. Removal, cleaning or preparation of surfaces in an urban area brought complains about noise and dust especially from the residents. The BIBER eliminates these complains.
  5. Overall the whole work is done by reduced costs.

4. Features of the robotization and automation

A key to the successful mechanisation of surface preparation is the use of BIBER System microelectronics. All components are using microprocessors for guidance, measurments and adjustment. The data are piped by a common data-bus and are available for each device of the system. In conjunction with the associated application program, the facade is measured, and the volume of surface to be removed is stated. The BIBER System application-software is IBM-compatible. The stored data can be used for further calculations.
The computer enables a gradual manipulation of the telescope arm. This parallel direction guides the machine head in perpendicular lines across the entire pre-measured surface.
At the end the System BIBER is a robot but did not work without an operator because of the demand for an outstanding security level on a public housing-construction site.

Through intelligent control panel manipulation, the operating of the BIBER System is easy. On a LCD all important data such as distance, angle of inclination are displayed. The data and the signals from the controls load the processor. The result is collision protection and automatic pressure regulation. At least the System is operated by one machinist. It substitutes five up to eight traditional workers. The mounting of the complete BIBER_System can be made be the operator and one handy man.

The BIBER System already offers the foundation for a more thoroghgoing control technology, which will enable the accomplishment of even more complexe tasks.
