Concrete Ceiling With Suspended Ceiling - Invacare EC-Track Installation & Technical Description

1. Drill holes with a 15 mm hammer drill to a depth of
54 mm. Blow holes clean.
2. Insert M12 stroke anchors into the hole (e.g. Hilti
HKD-S M12 or equal).
When using a setting tool (e.g. Hilti HSD-G M12x50
or equal), the anchor will be correctly fastened in the
concrete.
3. Mount the quick fitting by screwing the pre-mounted
threaded rod 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.
In order to ensure the achievement of max.
strength, the threaded rod should be screwed min.
14 mm into the anchor.
When using a stroke 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, push the hoist trolley
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.
Mounting with Standard Ceiling Bracket
The ceiling brackets are pushed onto the rail and
distributed with max. 2 m between each bracket and 200
mm from the last bracket at the end of the rail. Use at
least three brackets per rail. It is recommended to use an
uneven number of brackets, if only one person is installing
the rail. Thus, one bracket is placed on the center creating
balance when the rail is hung in the first bolt.
In at least one end of the rail, use a bracket with
locking screw to be secured to the rail.

1. Measure for the hole for the one expansion bolt of
the center bracket.
Drill the hole to a depth of approx. 80 mm with an
8 mm. impact drill bit. The hole is deeper than the
expansion bolt length to facilitate dismounting later
on. For dismounting, you can then drive the bolt fully
in instead of pulling it out.
2. Drive an expansion bolt M8x75 (e.g. Hilti HSA or
equal) in, leaving sufficient room for the bracket
thickness (6 mm), the locking washer (2 mm) and the
nut (7 mm) plus a little allowance. When you have
driven in the bolt, remove the nut and the washer.
3. Insert the hoist trolley in the rail. The trolley can be
oriented in both directions.
4. If you are installing the traverse trolley, make sure that
it is correctly oriented for the subsequent installation
of the traverse rail.
5. Install end stops at both ends of the rail. Insert the
adjustable end stops in the rail with the rubber plug
side first and the steel plate towards to the bottom of
the rail. Finger tighten the screws.
6. Lift the rail in place, mount the washers and nuts and
tighten them lightly. Adjust the rail lengthwise and
angle wise, and tighten the nut.
7. Drill the hole for the bracket in the one end of the
rail but on the opposite side of the rail. Drive in
the expansion bolt, make the final adjustments and
tighten.
Next, drill the remaining holes at one end of the
bracket slot. If the drill bit hits a reinforcement bar
before the hole is (50 mm) deep, simply drill at the
other end of the slot. If the drill hits the reinforcement
bars again, move the bracket approx. 20-25 mm along
the rail. The bracket will then cover the failed holes.
If the hole depth is between 50-70 mm, use
an extension bolt M8x57.
8. Drive in the remaining expansion bolts, place the
washers and nuts and tighten.
9. Position the adjustable rail stops correctly and tighten.
Make sure to position the end stops so that the hoist
does not hit the wall.
When installing parallel rail in a traverse system, be
sure to position the end stops at the exact same
points to ensure that the traverse trolley hit the end
stops simultaneously.

3.2.2 Concrete Ceiling with Suspended Ceiling

For rooms with suspended ceilings which are difficult to
dismount, it is recommended to choose a solution with
wall-mounted or wall support mounted rails.
If the false ceiling can be easily removed or in case of a
new mounting of a fixed suspended ceiling, we recommend
an installation with lowering brackets for aesthetic reasons.
For this solution, use the lowest rail profile S.
Mounting with Pendling Brackets
In the case of ceiling mounting, it may often be necessary
to pendle the rail downward. This need may arise in the
even of mounting in a room with a suspended ceiling,
where you have to pendle between the original ceiling and
the suspended ceiling, or if the ceiling is so high that you
have to pendle the rail down in order to ensure that the
hoist's lifting intervals are used as well as possible.
There are more possibilities when carrying out a mounting
with pendles:
