Service and Maintenance

Regular maintenance increases the safety of the crane system and minimises the risk of possible operational failures with high downtime costs. To comply with this safety aspect, we recommend that you subject GIS products to periodic maintenance. We offer maintenance work to our Swiss customers directly on site or in our service department at the Schötz site.


The installation of GIS crane systems has been carried out in Switzerland and neighbouring countries since 1969 mainly by the company Röhner in Gettnau. The long-standing cooperation with our service partners guarantees professionally installed and perfectly functional crane and vacuum handling systems.


After your crane system has been professionally assembled, we recommend commissioning by our service technicians. They will ensure the safe and flawless operation of your new or converted crane system. At the same time, training for operation and necessary maintenance work can be carried out for the operating personnel.
