INSTRUCTIONS FOR USE
YTONG wall
panels are shipped horizontally on their edges, and installed vertically or
horizontally.
The clamp has a
constant clamp force lock (torque wrench principle).
Every day before
using the clamp, check the clamp pressure with the aid of the pressure cylinder
and record the reading on the log sheet (Appendix 1). Pressure should be as
follows:
110 < Pressure < 140 bar (WKV 15-20 US FL & WKV 20-25 US FL)
130 < Pressure < 160 bar (WKV 24-30)
Vertical lifting and installation:
Attach clamp to
crane hook.
Move the clamp
to the end of the wall panel to be lifted.
Open the clamp sufficiently, depending on the
thickness of the wall panel, by turning the hand
wheel counterclockwise.
Rotate the clamp
90o on the handle so that the jaws of the clamp point toward the
wall
panel. The jaws of the clamp must be placed in the
center of the wall panel.
Set the clamp with the inner side of the clamp fully
against the wall panel. (see drawing below).
Apply pressure
to the clamp by turning the hand wheel of the clamp clockwise until you feel a
click and the green windows are visible (do not turn it any further after
this).
Now carefully
hoist the wall panel up and maneuver it into position.
When the wall
panel has been positioned correctly, the clamp can be removed from the panel by
opening the
clamp sufficiently. Do this by turning the hand wheel counterclockwise.
Attach clamp to
crane hook.
Four safety
strap suspension points are located on the (2) plates mounted to the clamp
jaws.
Attach the
straps with hooks to one side of the clamp and with triangles to the other
side.
Mark the center
of the wall panel to be lifted.
Open the clamp
sufficiently, depending on the thickness of the wall panel, by turning the
handwheel counterclockwise.
Lower the clamp
completely on the panel at the marked centerline.
Apply pressure
to the clamp by turning the hand wheel of the clamp clockwise until you feel a
click and the green windows are visible (do not turn it any further after
this).
Lift clamp and
panel ± 12” (300mm) above the ground and attach the safety straps under
the panel.
Connect both safety hooks to the opposite triangles.
Now carefully
hoist the wall panel up and maneuver it into position, disconnecting the safety
hooks from the triangles just prior to setting.
When the wall
panel has been positioned correctly, the clamp can be removed from the panel by
opening the clamp sufficiently. Do this by turning the hand wheel counterclockwise.
IMPORTANT
- Check the
clamp pressure with the special test-cylinder every day before using.
- Tampering
with the clamp is not permitted. The clamp has been calibrated in the factory.
- It is strictly forbidden at any time for
persons to be under the load during lifting !
- Handle the
clamp with care.
- The
maximum load-bearing capacity of the clamp may never be exceeded.
- Never
put hands, arms, feet, head or legs under the load, or between the jaws of the
clamp.
-
The load must always be hoisted;
it may not be dragged along the ground.
-
Avoid sudden movement to prevent
accidental release of the load.
- No alterations may be made to the clamp without the manufacturer's written permission. Any breach of this condition automatically invalidates all warranties.
- If the
lifting eye on the clamp is attached directly to the crane hook, the crane hook
must be able to move freely in the lifting eye. If not, use an extension.
- In
freezing weather, do not attempt to lift panels on which ice has formed.
Daily
- Check the clamp pressure with
the special test-cylinder every day before using.
- Check the clamp to insure it
is in good condition and working properly.
-
Any parts showing defects or
wear must be replaced by an authorized service representative.
The clamp must be serviced and checked by an authorized service
representative every (6) months.
If the pressure is not according to Appendix 1, return the clamp to an
authorized service representative for repair.
Transport/Storage
Keep the clamp,
with the jaws closed, in a dry storage area (stress-free) to prevent damage and
to keep dirt out. Keep the wall panel clamp clean. The pressure cylinder must
be stored in the box provided and kept with the specified clamp at all times.
APPENDIX 1
Instructions for checking
the clamp pressure of clamp type 12.99.52A - 12.99.60 – 12.99.80
This type of clamp is designed specifically for the vertical and
horizontal installation
of YTONG wall panels. Every day before using the clamp, check the clamp
pressure with the aid of the pressure cylinder and fill record the reading in
the log.
Method
1. Place the clamp on a solid
surface and open it at least 8“ (200mm).
2. The lifting eye must be at
the top of the clamp (see drawing).
3. Place the cylinder between the
clamp rubbers and carefully place the manometer on the surface.
4. Apply pressure to the clamp
until you feel the click and the green windows are visible.
5. Check the working pressure
using the manometer. Pressure should be as follows:
110 < Pressure < 140 bar (WKV 15-20 US FL &
WKV 20-25 US FL)
130 < Pressure < 160 bar (WKV 24-30)
If the pressure is either lower or higher than the values in the range, the clamp must be checked by an authorized service representative.
If the manometer shows the correct pressure, you may use the clamp. Record the details in the log and keep the
log with the manometer and the clamp.
The pressure must be recorded in the log daily.
