Mobile GIS slewing crane lifts space telescope CHEOPS

A special mobile slewing crane was developed for the University of Bern, which lifts the CHEOPS space telescope into a vacuum chamber for space simulations.

As part of the "Cheops” mission to investigate planets outside the solar system, GIS AG was able to provide the University of Bern with a very special slewing crane for the test lab. This was specially designed for use in a clean room environment and lifts the 65 kg space telescope CHEOPS in a vacuum chamber. In this chamber space simulations are carried out in the temperature range from -80°C to + 160°C. The mobile base of the slewing crane, movable on rollers was manufactured as a welded frame construction made of stainless steel. Also a corrosion resistant GIS electric chain hoist with a lifting capacity of 200 kg serves as a hoist. This was fitted with a two-stage, frequency-controlled drive for precise positioning of the space telescope. The electric chain hoist is operated via a remote control. Predefined temperature cycles are tested in the vacuum chamber by CHEOPS engineers in a first phase with a structural model (structural and thermal model), later with the space telescope. The deployment of the telescope in space is planned for the end of 2017.
