Yes. We carry out expert inspections and expert tests of designated and specified technical lifting equipment in accordance with Act No. 124/2006 Coll. and Decree of the Ministry of Labour, Social Affairs and Family of the Slovak Republic No. 508/2009 Coll. We hold a valid authorisation from the Technical Inspection of the Slovak Republic as well as an authorisation under the Mining Act.
