A thin levelling layer ensure a stable placement of the base

until an initial tensile force of approx. 30
kN is reached
Tightening torque for nuts to reach an initial tensile force of approx. 30 kN:
Swiss GEWI NG 28
Swiss GEWI NG 32
Tightening torque
400 Nm
400 Nm
Frost and icing-salt resistant mortar has to be used
Reinforcement: 12 mm-rod diameter in distance of 150 mm
If requested an installation template can be supplied.
It is important to ensure that the anchors have sufficient contact with the mortar and make good bond,
and a sufficient area to the surrounding material.
Further information about the anchoring of the base plate can be found on the anchor forces date sheet.
The forces that occur during a rockfall event are not to be underestimated. The civil engineering and in-
stallation work must therefore be carried out by professionals.
