Maintenance of Taaie Tiller

2021-10-05 (V. van der Wijk)

For the Taaie Tiller at the University of Twente to work daily without problems, regular maintenance is needed. Once a month I clean the algaes, which can grow very quickly and then block the sensors and waterpumps. Also inspection is needed for components that wear out, to replace them in time. Maintenance is an essential part of moving systems, for kinetic art works as well.

The impact of the mass of 300 kg falling from 3 meters high onto the structure that 'catches' the mass underwater is enormous. This week I replaced all the rubber dampers on one side that were completely worn out...not so bad actually after more than 4 years since the opening of the sculpture and more than 3000 (!) splashes or cycles since. I also installed two bracket clamps that have to prevent the catching structure to jump up too much. Because of the large impact, despite its 280 kg of mass it could jump up more than 15 cm, risking to come out of the pantoon.
