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.
