5.2 Ceiling mounting system
5.2.1 Concrete ceiling
Quick ceiling bracket
When using quick ceiling fittings, all ceiling fittings are to be mounted in the ceiling. Then the rail may be mounted
in these. At least 3 ceiling fittings shall be used per rail. There must subsequently be max. 700 mm between each
fitting. There must be max. 200 mm from the end of the rail to the first fitting.
Measure up to all fittings at the same time. It is important that the drilled holes are on a straight line. The precise
marking for the holes is to be carried out using laser technique, chalk line, etc.
When referring to mounting in concrete ceilings, we differentiate between the following:
Massive concrete: (Factory moulded concrete elements, prestressed concrete surfaces, armoured concrete)
Hollow surfaces:
Mounting in massive concrete and hollow surfaces
The holes are drilled with a 15 mm hammer drill to a depth of 54 mm. The holes are blown clean and Hilti HKD-S
M12 stroke anchors are hammered into the holes. When using Hilti running tools HSD-G M12x50, the anchor will
be correctly fastened in the concrete. When using other materials than this, the Hilti fastening equipment shall be
inspected, to make sure these are of the same quality and strength.
When the anchor is correctly mounted, the quick fitting is also mounted by screwing the threaded rod that is
premounted to the fitting in the stroke anchor. It is important that an adhesive is used on a fitting and nut when
the threaded rod is mounted to fitting.
Note! In order to ensure the achievement of max. strength, the threaded rod should be
screwed min. 14 mm into the anchor.
Note! When using HKD anchor in combination with the quick bracket, optimum accuracy
is a requirement. As an alternative, two component adhesive mortar for concrete can be
recommended.
When all fittings are mounted, the hoist trolley is pushed into the rail. The hoist trolley may face both ways. If
the traverse trolley is to be mounted into the rail, it is important that this faces correctly in connection to the
following mounting of the traverse rail.
The end stop is mounted in both ends of the rail. The end stop is pushed into the rail with the rubber plug first,
and fastened initially loosely with your fingers.
Lift up the rail, adjust the length of it and fasten it into all ceiling fittings.
Place the adjustable end stops correctly and tighten appropriately. It is important that the end stop is placed so
that the hoist does not hit the wall.
For parallel rails in a traverse system, it is important that the end stop is placed so that the traverse trolleys hit the
end stop at the same time.
