2.1: General instructions for installation of rails
All rails, including primary and secondary rails in a (x-y)/traverse system, must be installed horizontally. The ceiling or
floor alone is not accurate enough as a reference to horizontal. True to spirit level is required.
Overhang
Free span
Straight and true to spirit
The rails must be installed horizontally. In case of uneven surfaces, the mounting base must be straightened out by
means of washers, blocks, shims or similar.
The rails must be installed observing maximum free span and overhang limits. It is also essential for the performance
that deflection of the rails is avoided. The deflection for a fully loaded system must be less than 5 mm per running
meter. Reduce the distance between fixing points to achieve this.
For detailed information about maximum free span
and overhang for different rail profiles installed on different types of ceilings and walls using different types of fixtures,
please consult the ”MilkyWay Technical information” document; Span details.
The inside of the rails must be completely clean after installing. Even small filings or borings can affect the
performance, making traversing uneven.
The ends of all rails must be fitted with endstops. If there is a risk that the endstop may fall out, the endstop must be
installed with secure screws.
