Casos prácticos (Inglés)
DLR work plattform
1. The Customer
Deutsches Zentrum für Luft- und Raumfahrt
The Flight Operations department of the German Aerospace Centre (DLR) in Brunswick tests new developments on and inside aircraft under actual (non-virtual) conditions. The range includes aerodynamic studies, in-flight simulators as well as the testing of navigation systems and air traffic management systems. The research contracts come both from the DLR itself and from external universities, national authorities, industry or external research institutes.
In preparatory sessions, often lasting several weeks, the six aircraft and two helicopters are modified to cater for the requirements of the relevant research contract, components are fitted and modifications undertaken. It is only once extensive ground tests have been completed that the operation takes to the skies.
The main medium for conducting the research is a VFW 614 ATTAS (this stands for Advanced Technologies Testing Aircraft System) that is now over 20 years old. For more than two decades it has been flying throughout Europe on DLR test contracts.
2. The mission
Seitenleitwerk des Flugzeugs
For working on the lateral control system of the VFW 614 ATTAS a height-adjustable working platform needed to be designed. As regards the size requirements for the platform two factors were specified: 1) the width of the height controls that had to fit under the platform and 2) the need for an unencumbered projection distance of at least 1 metre.
The requirements on load capacity were particularly demanding because, in addition to two technicians, material and spares frequently also need to be accommodated on the platform. At the same time, weight savings were called for because the working platform needed to be light enough to be moved by two people without difficulty. This meant a full design specification which was duly drawn up by the DLR.
3. The Solution
In close collaboration with the DLR, ZARGES Aluminium Systems GmbH (ZAS) developed a concept that promised to meet the difficult and sometimes conflicting requirements. Repeated discussions and agreement with everyone involved in the project were called for until the optimum result was finally achieved – in particular as far as the height adjustment facility was concerned. “This was one of the most important pre-requisites for us, to enable us to carry out work on the whole of the side rudder easily and comfortably”, explained Stefan Schröder, the engineer at DLR responsible for new research contracts as well as for technical support inside the aircraft hanger.
The ZARGES height-adjustable working platform replaces the rigid scaffolding previously used, thus considerably simplifying the work. A graduated height adjustment facility means that the height of the 2,20 m x 4,50 m platform can be varied between 3,50 and 7,00 metres.
Maximum load capability has been increased to 300 kilograms so that two people and a wide range of materials can be accommodated on the platform. In the future, the development engineers and technicians will be able to carry out their work on the lateral control system of the ATTAS aircraft conveniently and safely.
„ZARGES has done a precision job here in translating our high requirements into reality.“

4. Special Technical Features
Height adjustment facility:
- Multi-level adjustment facility between 3,50 m and 7,00 m.
- Notches every 50 centimetres.
- Height-adjustable by means of hand crank with corresponding transmission action.
- Specially developed guide profi les for simultaneous increase in stability.
Weight:
- As light a weight as possible was one of the important criteria in the design specifi cation.
- Can be operated by two people without any diffi culty.
- Empty weight of 1260 kg with a load capacity of 300 kg. (Only 40 % of the weight of a steel construction)
Large platform with high load capability and 1,00 metre projection:
- Particularly large working platform (2,20 m x 4,50 m) featuring ample space for spares and tooling.
- Approx. 1,00 m unencumbered projection for maximum possible reach.
- Optimum tilt safety assured due to a broad crossbeam underneath the aircraft.

ZARGES Profi-Forum: What factors made it necessary to source a new working platform for the research aircraft?
Stefan Schröder: In the past few years we have used rigid scaffolding for work on the lateral control system on our VFW 614 ATTAS but we found that this was no longer meeting requirements. For instance, the scaffolding was not height-adjustable and it was not possible to reach all points of the lateral control system in such a way as to be able to work on them satisfactorily.
ZARGES Profi-Forum: So the height adjustment facility was one of the most important points?
Stefan Schröder: This was definitely an important factor as far as we were concerned. Thanks to its width, the new working platform can be moved into position via the height control and a height adjustment of between 3,50 metres and 7,00 metres can then be carried out in successive stages. Another factor that was important to us was a high load capability on the working platform because, in addition to two staff members, materials often need to be taken up on to the platform as well. However, at the same time we wanted to keep the weight as light as possible so that the platform could be moved by two members of staff without difficulty.
ZARGES Profi-Forum: How did the collaboration with ZARGES come about?
Stefan Schröder: We already knew ZARGES from many other projects and working platforms that we use on our aviation instruments. Both during the project stage and at the implementation stage we found that, with ZARGES, we had identified a good partner for a special solution of this nature. The team has managed – always in close cooperation with ourselves – to find the best possible solution for the demanding requirement.
Aircraft Docking Systems
Equipment, working platforms and docking systems for civil and military aircraft and helicopters, weapon systems and space technolog. Fitting to complex contours of engines, rotors and tail units. Safe, optimum and swift access. High flexibility and variabilty. Reduction of downtimes.
Most often a docking system is made of dozens of individually moved modules or docks to be placed around an aircraft to perform its maintenance.
But the user needs that all these modules or docks be perceived as one single overall station with coordinated shapes around the aircraft and movements designed to reduce the time lost for getting out and entering into the docking station.
So project management is organized in the following phases:
- Overall system design and breakdown into modules,
- Functional design of the modules or docks by means of an experienced and specialized design office using a 3D CAD software and standard elements library,
- Design review with the customer to verify that his need has been perceived in all details,
- Detailed design,
- Manufacturing, including factory pre-assembly for technological and safety quality control,
- Partial de-assembly, transportation and final assembly at the customer’s premises,
- Final acceptance tests, training and documentation.
