Above our heads: fascinating projection sphere in the Museum of the Future
We manufactured this projection sphere with a diameter of almost 3 m from GRP for the German Museum in Nuremberg. It was made from four segments and installed on site on the 8 m high concrete ceiling.
First, a mold for a ¼ ball segment had to be milled. This form was then molded with GRP in a thickness of 4 mm. Each of the four ball segments has an inner flange so that they could later be bolted together. A mounting opening with a diameter of 450 mm was provided.
Three chains are attached to the ball to prevent it from swinging back and forth. 3 movable eyebolts were mounted on the ceiling to move the sphere at intervals of 2 meters.
from the ceiling. Sling chains in accordance with DIN EN 812-2 quality class 8 with a load capacity of 1,120 kg were used for fastening.
The sphere was painted in RAL 7035. And weighs approx. 300 kg.
The projection sphere is intended as an oversized globe in the “System Earth” exhibition area. A simulation of the earth with its oceans, landscapes and cloud fields will be created by projecting 10 beamers.
