DANGER of falling!
Work may be necessary directly at the edge of the pit during installation.
Carelessness or wearing inappropriate clothing could result in a fall. There is

• Thestructuralcomponentsandfoundationsmustbeofsufcientstabilityinorderto
allow the product to be anchored securely and functionally. The operator or the supplier
is responsible for the provision of the foundations and their suitability in terms of di-
mensions, stability and strength.
• Observe all regulations, rules and legal requirements for working with and underneath
heavy suspended loads.
• Please also observe the applicable national accident prevention regulations and trade
association safety provisions.
• Inspectthecoatingbeforeinstallation.Ifdefectsarefound,thesemustberectied
before installation.
5.1. Working steps
Installation takes place in the following steps:
1. Mounting the guide pipe bracket
2. Mounting the coupling base
3. Mounting the guide pipes
4. Mountingthecouplingange
5.2. Basic tasks
Various fastening systems are used when mounting the individual components.
Thefollowingsectiondescribeshowtoinstalltheindividualsystems.
5.2.1. Fastening with bolts and masonry anchors
1. Markoutthedrillholes:Makesurethereissufcientdistancetotheedge.Thismust
be at least twice the length of the anchor. This prevents the material from cracking or
chipping.
2. Drill the holes: The size of the hole depends on the size of the anchors. The size is
markedontheanchor.Forexample,asize6anchorrequiresaholediameterof6mm.
3. Hole depth: An anchor fastening will only hold if it is deep enough to take the bolt.
Thismeanstheholedepthdependsontheboltlength.Theholeshouldbe5mmdeeper
than the bolt length.
4. Clean the drilled holes: Masonry dust impairs the strength of the anchor. Therefore,
always blow or vacuum out the hole.
5. Putintheanchor:Puttheanchorintotheholeuntilitisushwiththewall.Takecare
not to damage the anchor when inserting it.
Damaged or used anchors must always be replaced.
