5.7 Mounting traverse system
The parallel rails are mounted in ceiling or wall as described
in the previous section on the current mounting conditions.
Either if the two parallel rails are mounted using quick or
standard fittings, it is important that any deviation of parallelism
of the two rails does not exceed +/- 2mm.
When mounting parallel rails, it is important to take into account whether it must be possible to insert a traverse
trolley later on or not. If not, the rails may run all the way out to the wall (minimum distance from rail to wall
must always be 60 mm). In this case it is important that the traverse trolley and end stop are pushed into the rail
before the rail is mounted. However, if it should be possible to insert the trolley later on, it is important that there
is a minimum distance between the one end of the rail and the wall of 350 mm.
Remember that the end stop in the parallel rails is to be placed so that the two traverse trolleys hit the end stops
simultaneously.
The distance between two parallel rails is always measured from centre to centre of the two rails.
Generally, the following applies to the traverse rail with reference to the free span between the parallel rails as
well as the max. protrusion a rail can handle.
•
Rail profile S:
Max. free span 2000 mm, max. protrusion 200 mm
•
Rail profile M:
Max. free span 4000 mm, max. protrusion 400 mm
•
Rail profile L:
Max. free span 8000 mm, max. protrusion 500 mm
Note! When a rail is mounted as partially between-hung, it is always the max. protrusion for the
S-profile that is applicable.
When mounting the traverse rail, there are three possible methods:
The traverse rail is between-hung
The measurement for the traverse rail is always the distance between the two parallel rails minus 86 mm.
When the traverse rail is mounted between-hung, the hoist trolley is inserted in the traverse rail and the end stops
are placed loosely in each end of the traverse rail. Remember that the rubber plug on the end stop always should
face inward toward the hoist trolley. Lift the rail on top of the traverse trolley, so that the end stop's 2 bolts align
with the two holes in the traverse trolley, then secure it with washers and lock nuts. Before the rail is securely
fastened, it is important that the distance between the traverse rail and each of the parallel rails is equal in both
ends. When the rail is secured, install the cover plugs on lock nuts and in the rails.
