User Instructions - Part 2
1. Safety Instructions
Please take into consideration extreme circumstances or
shock loads when choosing components.
The ICE-Balancer must not be used under load with an
inclination angle of greater than 10° (see pic 11).
The inclination angle ß must not exceed 45° (90° internal
sling angle) refer pic 13 and 14.
ICE-Balancers must only be used by designated and trained
persons by observing the BGR 500 requirements, chapter 2.8,
and outside Germany acc. to the country specic regulations.
For Australia, please refer to AS 3775.2.
2. Intended Use
ICE-Balancers are installed into 4-leg sling assemblies (2
x 2-leg), to achieve an equal load distribution to all 4 legs
(pic 17). The length tolerances of the single legs will be
compensated by the disposition of the ICE-Balancer.
Please ensure that the ICE-Balancer does not exceed the
limit inclination angle of 10° (pic 11). By the special shape of
the ICE-Balancers you can easily realise the limit inclination
angle of 10°.
During use ensure that the 2-leg sling with the balancer is not
used separately.
Observe the safety instructions: “Lifting means used for lifting
of loads must especially avoid that loads shift unattended or
drop in free fall.”
ICE-Balancers must only be used in the conditions stated in
this instruction.
You can calculate with 4 load bearing strands if the following
criteria are followed (BGR500):
• Two 2-leg slings, one sling with a balancer.
• Both 2-leg slings attached to one hook (single or double
crane hook)
• Symmetrical load spreading/sharing
• Max. inclination angle ß 45° (90° internal sling angle)
WARNING
The 2-leg sling with the balancer should not be used
seperatly as a 2-leg sling. Lifting means for lifting of
loads must avoid that loads can shift unintentionally.
3. Assembly and Instruction Manual
3.1 General Information
• Capability of temperature usage:
When used at temperatures higher than 200°C the working
load limits (WLL) of the ICE-Balancer must be reduced as
follows:
-60°C up to 200°C no reduction
200°C up to 250°C minus 10 %
250°C up to 300°C minus 40 %
Temperatures exceeding 300°C are prohibited!
• ICE-Balancer must not be used with aggressive chemicals
such as acids, alkaline solutions and their vapours.
• The balancer head consists of the following components:
• IAK-Master Link
• VV-SCH / VC-SCH
• ICE-Balancer
• IVS ICE-Connecting Link
3.2 Assembly Instructions
3.2.1 Assembly of masterlinks and shackles
Please observe the correct sizing of masterlinks, shackles
and balancers during assembly and repairing (see table 2).
During the assembly of the balancer sling please proceed as
follows:
1. Align the components to be assembled (Pic 1).
2. Attach shackle bow into IAK-Master Link.
3. Move shackle bow and IAK Master link over the top hole of
the balancer plate.
4. Close shackle by placing the shackle pin through the
balancer plate connecting hole.
5. Turn shackle pin completely in and secure it always with a
cotter or a sleeve pin. The shackle must now be securely
connected to the balancer.
NOTE
The bow of the shackle must always be secured:
Cotter pin for VC-SCH 5.0 and VC-SCH 6.0
Sleeve pin for VV-SCH 10, 13 and 16

4. Assemble both parts of the connector ensuring all
components are aligned (Pic 7).
5. Install load pin into the bore of the eye (Pic. 8). Both bow
parts are now connected with each other.
6. Secure the assembled connecting link (Pic. 9):
• Position the securing pin.
• Knock sleeve pin in with a hammer.
7. Finally check the correct assembly (see section 4
inspection criteria).
3.2 Assembly Instructions
3.2.2 Assembly of chain strands (using connectors)
The chain strands are connected to the balancer using IVS
ICE-Connecting Links.
Sequence of assembly:
1. Install last chain link into the nose (Pic. 3).
NOTE
At the beginning of the bow rounding, the chain link
can be turned 90° within the bow (Pic.4).
2. Position chain strand to the bottom of the bow part (Pic. 5).
3. Assemble the second bow part of the connector into the
balancer plate (Pic. 6).

3.3 Usage (limit of inclination angle)
• Before each use please ensure the correct assembly of the
ICE-Balancer.
• Observe that the inclination angle of the ICE balancer does
not exceed 10° (see pics 10 to 12).
NOTE
The maximum allowed balancer skewing of 10°
can be recognised by the specic shape of the ICE
balancer. The limit skewing angle of 10° can be easily
recognised.
User Instructions - Part 2
10° -edge
Pic 10: In the ideal case no skewing of the balancer
should occur 10° edge.
• A skewing of the balancer under load by more than 10° is
prohibited (Pic. 12)!
The 10° edge is no longer aligned horizontal!
The skewing of the balancer is too big.
WARNING
Skewing of the balancer by more than 10° is
prohibited Should the limit skewing angle
exceed 10°, either an ICE-CURT-GAKO length
adjustment has to be installed into the 2-leg
balancer sling or a shortening element must
be used. Make the chain strand either longer
or shorter until the balancer is within the 10°
range.
Pic 11: Limit skewing inclination of 10° reached

3.4 Usage (Inclination angle β)
• Pay attention that the inclination angle ß will not exceed
45° (90° internal sling angle) refer pic 13 and 14.
• Ensure the load is transferred without twists or kinks in the
chains or components.
• Before each use, the complete ICE-Balancer assembly,
including all components shall be throughly inspected (see
section 4 inspection criteria). Refer to AS 3775.2 for care
and use.
ATTENTION: Please inspect all components prior to
use. Damaged, incorrect assembly or improper use may
result in serious injuries and/or material damage.
• Leave hazardous area when possible.
• Always monitor attached components or lashed loads.
• Read all relevant safety instructions/user instructions.

3.4 Regular inspection
An annual inspection or sooner if conditions dictate should
be carried out by a competent person examining the
continued suitability. Also, inspect after damage and special
occurrences.
4 Inspection criteria
Check and control the following points before each initial
operation, in periodical periods after the assembly and after
special incidents:
• The ICE-Balancer should be complete
• Deformation of component parts
• Complete, readable WLL statements as well as
manufacturers identication
• Mechanical damage, such as strong notches, particulary in
high stress areas
• Reduction of cross-section due to wear >10 %
• Evidence of corrosion (pitting)
• Evidence of cracks
5 Repairing
• Repair can only be carried out by the manufacturer or by
competent person.
• Only RUD original spare parts must be used and all
repairing and overhauling operations must be documented
in the chain card le (of the complete lifting mean) or the
RFID-System®.
RUD VIP and ICE chains and components are designed for
a dynamic load of 20.000 cycles according to DIN EN 818
and 1677 standard. The German Employer´s insurance
Association (BG) recommends:
• When high dynamic stress combines with high number
of load cycles, the bearing stress must be reduced to
Mechanism group 1Bm (M3 acc. to EN 818-7).

ICE-BALANCER
User Instructions - Part 3
ATTENTION
When using two 2-leg slings at a symmetrical load
distribution, one with a balancer, and both slings
are attached into the same hook, 4 load bearing
legs can be assumed. The inclination angle ß
must not exceed 45° (90° internal).
Example ICE 10 mm:
When using a standard 4-leg sling in the worst case scenario,
the user can calculate with only 2 load bearing legs.
Refer AS 3775.2 / BGR 500, chapter. 2.8 clause 3.5.3:
When lifting with multiple strands only two strands can be
assumed to be load bearing.
This is not valid if it is guaranteed that the load will be
distributed equally to 2 additional legs.
By using the ICE-balancer, the load distribution of a 2 x 2-leg
sling will be forwarded to all 4 chain legs.
ICE 16 mm standard 4-leg sling:
WLL = 21.6 t @ 60° inclined sling angle.
With ICE-Balancer:
WLL = 43.2 t @ 60° inclined sling angle.
