WinGrip
AIO
®
1 General information
Instructions shall be retained and
provided to all Users of Latchways
WinGrip AIOs in the language of the
destination country, even when resold.
Failure to follow these instructions may
cause serious injury or death.
Users of Latchways WinGrip AIOs shall
be medically fit and formally trained
in the use of the system by MSA or
an appointed MSA training partner.
Latchways WinGrip AIOs shall not be
used by pregnant women, minors or those
under the influence of alcohol or drugs.
Latchways WinGrip is a temporary anchor
solution that utilises vacuum technology
to enable quick, temporary, safe access
to maintenance and construction
areas without permanently affecting
the interfacing substrate. Latchways
WinGrip may be used on surfaces similar
to aircraft wings that are even/flat, non-
porous, free from contamination and dirt.
Latchways WinGrip AIO is supplied with a
self-contained high pressure gas cylinder
and has a sealed vacuum area of 0.13 m
2 Intended use and product
limitations
Latchways WinGrip AIO is designed for
a single User per attachment point. The
maximum User weight (including tools
and equipment) is 140 kg. It is lightweight
(6 kg) and portable and may be used in
both wet and dry situations.
• Operated solely on compressed air
or nitrogen, no electrical requirement
making it intrinsically safe to use with
open fuel tanks.
• Working temperature range of -12°C
(10°F) to + 50°C (125°F)
• 20 minutes of safe use after vacuum
generation has ceased
• Latchways WinGrip may be used at
any angle between 0º and 90º. It is not
suitable to be used upside down.
• The device shall not be positioned such
that water could accumulate and create
a hazard, or used when there is a risk
of frost or freezing conditions where the
conditions create a hazard.
• The anchor device shall only be used
for personal fall protection not for lifting
equipment.
Designed to be used in restraint for
maximum safety and also arrest capable;
with a minimum nominal radius of 1.6 m.
The Latchways WinGrip AIO (Figure 1)
equips the User with a means of limiting
the dynamic forces exert on the User
during a fall to a maximum of 4 kN.
Latchways WinGrip AIO rubber seal
composition offers resistance against
aerospace fluid contaminants whilst
maintaining flexibility and a high shear
loading. The maximum loads transmitted
from the anchor to the surface is 89.1 kN
per m
2
; this force is horizontal.
3 Pre-use checks and periodic
examination

.
The safety of the User relies upon the
continued efficiency and durability
of the equipment therefore pre-use
checks shall be completed before each
use as specified in Table 1. Periodic
examinations shall be completed by
1
a Technician
, in accordance with the
manufacturer's instructions. The interval
will be dictated by the usage (Table 2),
local regulations or environmental
conditions and shall be at least annually.
It is recommended that the device is
marked with the date of next examination.
Records shall be kept of the results of the
examination (page 55).

1. Technician: a person, other than the User, who is trained by
MSA to examine, repair and recertify Latchways WinGrip AIOs,
in accordance with MSA's instructions.
Latchways WinGrip AIO shall not be
altered or added to and shall be repaired
by a Technician
1
in accordance with the
MSA's instructions.
Air Supply:
Latchways WinGrip AIO is designed to be
used with the Latchways WinGrip cylinder
or a clean, dry supply of compressed
air*, including outside of hanger with a
nitrogen trolley.
Whilst it is possible to use lubricated
compressors system, performance may
be affected due to the potential for liquid
or particle intake.
The use of an additional vacuum anchor
via a primary hose will greatly reduce the
working time of the cylinder. It is therefore
advisable to use shop air when a task
requires the employment of the flying
anchor. The cylinder may be stored on the
Latchways WinGrip AIO and used as an
additional supply in an emergency situation.
An additional cyclinder may be stored on
the Latchways WinGrip Flying Anchor for
use for system evacuation (Figure 6).
4 Installation and use
A written rescue plan and the means to
implement it shall be in place to deal with
emergencies that may arise during use.
Ensure PPE is suitable, worn correctly
and fulfills site specific criteria. For
*80 - 120 psi compressed air or nitrogen.
installation steps see Figure 2.
Installation of a vacuum anchor has
three phases - Surface, Installation and
Integrity.
Safe access
At all times access shall be achieved in
a safe manor; observing the hierarchy of
risk for fall protection.
At all times it is preferable to work in
restraint. When moving, restraint is
achieved through good rope discipline
Table 3. When working in restraint is
not possible and there is a potential to
fall (e.g. working at a wing tip), then fall
clearances shall be known and the fall
path kept clear. Minimum fall clearance
is indicated in Figure 1. The maximum
deflection of the anchor and energy
absorber during a fall is 1 m.
Careful consideration shall be given to
access to the wing. Where a suitable
anchor point is not available the flying
anchor shall be used to achieve safe
access (Figure 3).
5 Cleaning, maintenance and
storage
The system components may require
cleaning or disinfecting after use.
Components shall be thoroughly
rinsed, using warm water and domestic
detergent, and allowed to dry naturally,
away from direct heat. Methyl alcohol may
be used to remove heavy dirt deposits on
metal and rubber components only.
Solvents, thinners and chemical cleaning
agents shall not be used unless specified
by MSA.
When not in use the Latchways WinGrip
components shall be stored in the case
supplied; compressed air or nitrogen
vented and vacuum vented from the
anchors. Components shall be protected
from direct sunlight, excessive heat, high
humidity, sharp edges and corrosives.
The components shall not be subjected
to unnecessary stress, pressure or rough
handling. Wet components shall be dried
naturally away from direct heat.
