Since 1 January 2007, the revised crane regulations have been in force, setting out the requirements for the safe use of cranes. You can find more information at www.suva.ch under the section SUVA Pro, industry/specialist topics.
Die EKAS Directive 6511 stipulates daily and annual inspections:
Annual inspections by a specialist
We carry out the periodic, annual inspection of your crane professionally and at a competitive price, and if necessary we initiate the required steps to ensure the safe operation of your crane and compliance with legal regulations.
The daily checks can be carried out by the crane operator, but the annual inspections must be performed by a crane specialist!
