4 (16) CLT Lifting Guideline
4-leg gear with a load distributor:
(examples)
Each lifting point is loaded equally with 1/4 of the total load if
center of gravity and lifting points are lifted symmetrically.
In other cases, load-bearing capacity has to be reduced at
4-leg gear without a load distributor:
(example)
* Despite symmetrical alignment the total load is not
distributed equally to all 4 lifting points. Therefore load-
bearing capacity has to be reduced at least by 25 %.
This can be reasoned because not always each chain has
exactly the same length and because there are also always
3-leg gear:
There are two conditions to distribute the total load equally to all
3 lifting points:
• All lifting points must have the same distance from center of
gravity.
• The angle between lifting points must be always 120°.
The lifting points are aligned within a relatively small area.
Having long panels this will cause higher deflection during
lifting. Therefore, three lifting points are only useful for quadratic
or small panels.
Wall panels are delivered in most cases horizontally. To upright such panels it has to be checked whether the load-bearing capacity of the
lifting device works in both directions.
