FEATURES OF THE ANCHORING DEVICES AND BRACKET ASSEMBLY
The materials and minimum thicknesses required according to the type of roof on which the anchoring
devices in the INBRKT.XNrange are installed are given below. The following table refers to the roof profile, on
which fixings must be done exclusively using the rivets supplied by HARKEN.
FEATURES
STEEL SANDWICH PANELS MINIMUM THICKNESS 0.4 mm
ALUMINIUM SANDWICH PANELS MINIMUM THICKNESS 0.6 mm
STEEL SHEET MINIMUM THICKNESS 0.6 mm
The INBRKT.XNbrackets are supplied with rivets and standard fixing feet and relative fixing bolts.
Using:
• standard fixing feet,
• the fixing bolts between these and the other components of the device,
• the rivets supplied by HARKEN,
on corrugated sheet and sandwich panels of suitable thicknesses, for which fixing between the anchoring
device and the corrugated sheet and sandwich panel is suitable.
Check the seal between the sandwich panel or corrugated sheet and the underlying structure, as well as the
ability of the latter to resist the forces transmitted by the anchoring system.
The system has been tested in compliance to:
- UNI 11578:2015 type D for use by 4 operators at the same time
- EN 795:2012 type D
- CEN/TS 16415:2013 type D for use by 4 operators at the same time.
For some corrugated sheet the standard fixing feet shape may not be suitable. In these cases it is possible to
design and use non-standard support bases/fixing feet: these must be sized by the designer qualified for
structural calculations as they are a part of the anchoring device fixing system. The project also includes the
calculation of the fixing sizes: the type of rivet/screw, their number and arrangement (in this case there is no
obligation to use rivets supplied by HARKEN as the sizing is done by an external designer).
The situation described below refers to the field tests for connection between sandwich panel/corrugated
sheet and the underlying structure.
As shown in the following figure (Fig.1) the tests were carried out on 2 portions of roof, each measuring d1=
2 m and d2=1 m, coupled together to form a surface area of 2 m x 2 m. The distance between the fixing rows
was, for the purpose of safety, the maximum permitted by the corrugated roofing manufacturer, i.e. d3=1.5
m. The fixing used met the requirements of the corrugated roof manufacturer’s technical data sheet, for
fixings on iron omega profiles, as this was the type of underlying structure: the fixing was chosen according
to the underlying structure (wood, steel, reinforced concrete, etc., and their characteristics). A fixing was
installed on every corrugated angle, both in the upper and lower fixing row in relation to the device
positioning: during the test, the omega profiles were found to be solidly fixed to the test field structure. The
device fixed on the corrugated roof using the rivets supplied did not overlap or cross a fixing row.

ANCHORING DEVICE TO RAIL R27 LS + INBRKT.XN
The fall protection system consisting of the rail R27.LS + brackets for sandwich panel or corrugated sheet is:
- Certified UNI 11578:2015 type D for use by 4 operators at the same time
- Conforming to EN 795:2012 type D
- Conforming to CEN/TS 16415:2013 type D for use by 4 operators at the same time.
Figure 1
The maximum number of users at the same time can be decreased by the designer or inspector/maintenance
operator for motivated reasons which many not have been envisaged during the design and manufacture of
the device, for example linked to the place of installation or the resistance of the fixing and the support.
Single- and multi-span device used to obtain lines of indefinite length. The maximum span is 3 m. For lines
consisting of 2 or more rails, install intermediate supports, which will form spans of maximum 3 m length
(measures taken from the plate centre to the adjacent plate centre, see Fig.2).

FEATURES
FALL PROTECTION SYSTEM

16/01/2020 ENGLISH 11
The anchoring line to connect to is the rail R27 LS (Fig.5), from which it is possible to work when using
suitable PFPE (Personal Fall Protection Equipment) to protect from falling in restraint, work positioning and
fall arrest. It is possible to connect to the rail directly using one or more trolleys in the Access Rail System
series (see R27 Long Span Instruction Manual).
The maximum number of operators working on the rail at the same time, each with their own trolley, is 4 per
span. These operators must have maximum weight 100 kg each.
To use the system for human suspension system, the line must be stiffened using the stiffening brackets
INBRKT.X4, to create spans of MAX 1.5 m (Fig.6).

INSTALLATION METHODS
INSTALLATION ON CORRUGATED ROOFS OR SANDWICH PANELS
Before fixing the anchoring devices to the sandwich panels or corrugated sheet, check that these supports
comply with the minimum conditions set out in the table in the previous chapter.
INSTALLING THE SEALS
Remember that before proceeding with the installation of each device or element, apply the anti-infiltration
seal supplied for each foot. The following diagram shows the procedure to be followed for installation
(Fig.30):
ANCHORING DEVICE
Having pre-assembled the end and middle brackets, without fully tightening the bolted joints, to allow the device
to remain mobile and be adapted when installing the feet on the panel corrugations, proceed to install it on the
profile crown of the corrugated roof. When installing the end and middle brackets on the roof, make sure that
the system is straight and there are no bends in the rail when seen from above. Before proceeding with
installation, check that there are no impediments (obstacles such as roof windows, chimneys, etc.) which could
interfere with the correct operation of the rail or prevent the correct positioning of the devices according to the
design. If deformities are found which do not allow the design to be followed or the installation to be performed
correctly, stop installation immediately and consult the designer. Having correctly installed the end and middle
brackets, proceed to install the rail components (rail, connectors, endstops, etc.).
Figure 30

20 ENGLISH 16/01/2020
END BRACKETS (CODE INBRKT.X5)
Position the device on the profile crown of the corrugated roof: the standard tie-rod arm fixing foot must be
installed above the sheet where the roof portions overlap, in the opposite direction to the starting direction of
the rail, but on the same axis. Having positioned the device on the sandwich panel or corrugated sheet, check
that the fixing feet adhere to the roof profile crown, i.e. that the foot angle coincides with that of the corrugations.
After checking this, fix the feet to the corrugation using the rivets (9 for each standard foot, for all 5 feet). Before
inserting the rivets, using the installation feet as a template, pre-drill a 5.4 mm hole. Install the rivets using a
suitable riveting tool for 5.2 mm diameter rivets.
Having riveted the fixing feet into position, tighten the bolted joints to a tightening torque of 60 Nm (figure 31).
Figure 31
INSTALLATION METHODS
WARNING!
Ensure anchoring feet are fully compressed to the roof sheet and that pressure is maintained
during rivet forming process, to ensure deployment of the rivets back to the roof sheet.
