1 Basic Specifications
Attachments using chemical anchors FHB dyn may only be carried out in accordance with the provisions of
the general building approval Z-21.3.1748. Non-compliance with the provisions leads to the exclusion from
responsibility and liability of the anchor manufacturer, supplier, and technician.
The transfer of loads from crane operation to the component via the anchor attachment must be verified by
the building contractor or his representative. Possible damage to the ceiling or floor reinforcements due to
drilling work, which has a static effect on the building structure, must be taken into account. If necessary, the
permitted position of the drilled holes for mounting must be indicated.
Schmalz will only perform mounting if all requirements have been met by the time of mounting and the mounting site
has been prepared accordingly. If the requirements are not met, alternative solutions must be found. If, during
mounting, it is determined that the requirements have not been fulfilled as stated in this confirmation, additional
costs will be charged to the client.
