R27LS RAIL
The anodized aluminium R27LS rail (INR27.LS) must be fastened to a supporting structure using suitable
brackets. A low friction trolley, is to be installed to the rail, providing a mobile anchorage point. This assembly
includes a rigid fall arrest system. By installing and using this system correctly, the risk of the operators falling
whilst working at height can be eliminated or significantly reduced.
Furthermore, the R27LS rail in horizontal installation (0°±5°) can be used as a Rope Access Anchorage
System, to provide a safe anchorage for twin rope working (rope access & work positioning), with good
anchor mobility under load.
COMPONENTS
The R27LS rail must be used with the following components:

Bent rail with a minimum radius of curvature of 15m (valid for all trolleys)
The straight rail can be installed on bent surfaces, which have a minimum bending radius of 15m.
The bending rail can be done manually in the 3 directions during the installation procedure and to do this, it is
necessary to install the rail using a minimum of four brackets with a maximum distance of 1m between a bracket
and another. See paragraph Installation Layout – bent rail 1, 2 and 3.
