Threaded rod
Articulated girder
The ceiling-mounted bracket 2LP/M16 or M20 is bolted onto two cup square bolts. The cup square bolts are inserted through holes in a concrete element and secured on the other side with counter plates.

The figures show the installation of a ceiling-mounted bracket 2LP/M16 or M20 with projecting threaded rod (with normal suspension, short suspension and normal stiffener). The installation of a ceiling-mounted bracket 2LP/M16 with bolted-on articulated girder (with normal stiffener, inclined suspension, inclined stiffener and V-suspension) does not differ significantly from this. |

The figures show the installation of a ceiling-mounted bracket 2LP/M16 with bolted-on articulated girder. The installation of ceiling-mounted bracket 2LP/M20 does not essentially differ. |
|
|
The installation of the ceiling-mounted bracket 4LP/M20 is described in the product manual "Installing the ceiling-mounted bracket 4LP/M20 and craneway suspension M20". |
On every ceiling-mounted bracket 2LP/M16 or M20:
|
|
Where and at what intervals the ceiling-mounted brackets are fixed to the supporting structure is specified in the planning documents. |
The specified dimensions, positions and clearances must be followed exactly.
|
Ceiling-mounted bracket centred in relation to HB profile rail |
Ceiling-mounted bracket perpendicular to HB profile rail |
|
| |
|
Later-installed HB profile rail |
Suspension distance LB |
Position the drilled holes so that the
ceiling-mounted bracket will later be exactly centred in relation to the
later-installed HB profile rail.
This is necessary so that the HB profile rail can later be aligned.

On the other side of the concrete
element, press a wooden beam (for example) against the exit point of the drill.
This ensures the concrete element does not crumble as much during the
drilling.
Observe occupational safety
regulations and use a suitable impact drill (appropriate for the material of the
concrete element) to drill two thru-holes in the concrete element:
─ Drilled hole diameter: 20 mm
─ Drilled hole spacing: 190 mm
On every ceiling-mounted bracket 2LP/M16 or M20:

Counter plate |
Cup square bolt |
|

|
|
Concrete element |
Insert cup square bolts (2x) with
counter plate (1x each) through the concrete element from above.
This section only applies to the ceiling-mounted bracket 2LP/M16 with bolted-on articulated girder (with normal stiffener, inclined suspension, inclined stiffener and V-suspension)
On every ceiling-mounted bracket 2LP/M16 with articulated girder:
The articulated girders can be mounted lengthwise or crosswise to the ceiling-mounted bracket 4LP/M20 as appropriate for the alignment of the supporting structure.

Articulated girder |
Insert M16x35 rib screw through
articulated girder.
Insert articulated girder with rib
screw in ceiling-mounted bracket.
Screw the M16 rib nut loosely onto the
rib screw from the back.
Shift the articulated girder
lengthwise or crosswise to the ceiling-mounted bracket as necessary.
Screw the rib nut on. 300 Nm.
On every ceiling-mounted bracket 2LP/M16 or M20:
|
Retaining plates |
Cup square bolt |
|
| |
|
Clamping plates |
|
Insert retaining plates (2x),
ceiling-mounted bracket (1x) and clamping plates (2x) on the cup square bolt
from below.
Loosely screw on the ceiling-mounted
bracket with the M16 rib nuts (2x).
Position the ceiling-mounted bracket
so that it is exactly centred in relation to the later-installed HB profile
rail.
This is necessary so that the HB profile rail can later be aligned far enough to the left or right. The ceiling-mounted bracket can later be shifted 12 mm to the left or right.
Screw on the M16 rib nuts (2x)
initially hand-tight.
The rib nuts will later be tightened to the correct torque (after aligning the HB profile rail).
If final alignment of the ceiling-mounted bracket 2LP/M16 or M20 can now be done:
Screw the rib nuts tight.
90 Nm.
