Lifting Lugs for Steel Constructionsfinnish_translation.jpg

Nostokorvat teräsrakenteisiin

These lifting lugs are not to an angle lifting. Sharp edges removed.
Use to equipment and structures assembly. These are not lifting equipment.

 Material  S235JRG2

The variables are the material thickness and stress in relation to the load.

Capacity     Plate       Width       Height       D         Weight

   kg             mm          mm         mm         mm          kg             Calculation

 1 500            8            100           90           58           0.30         Known weight

 3 000          12            100           90           58           0.52         1.253 x 0.30 = 0.58 kg

 5 000          20            100           90           58           0.87         1.255 x 0.30 =  0.91 kg

D = 40 mm from the bottom

1.6 - 2.0 - 2.5 - 3.15 - 4.0 - 5.0

How About the Lifting Lug 6 300 kg?

 

1.6 - 2.0 - 2.5 - 3.15 - 4.0 - 5.0 - 6.3

                                                   1.     2.      3.       4.      5.     6.

1.256 x 0.30 =  1.14 kg

 

0.3 -  0.4 -  0.5 -  0.63 -  0.8 -  1.0 -  1.12    kg

                                  1.5    2.0    2.5    3.15    4.0     5.0     6.3    x 1000 kg

                                             1.      2.       3.       4.       5.       6.

The sixth step exceeds the proportionality and must often therefore be crossed out. In this case the sixth step is quite accurate value of the lifting lug. Still take material S355 for this product, because the material cost difference is small.
