Weight support capacity
(Min)
Unit Element fenders can support a lot of weight. The table
is a guide to the permitted weight of front panel before
additional support chains may be required.

E1 W H ≤ n × 690 × H × L W V ≤ n × 1230 × H × L
E2 W H ≤ n × 900 × H × L W V ≤ n × 1600 × H × L
E3 W H ≤ n × 1170 × H × L W V ≤ n × 2080 × H × L
n = number of element pairs
W H = panel weight – elements ‘V’ on elevation
W V = panel weight – elements ‘V’ on plan

Fenders in tension
There must be enough space around and between Unit
Element fenders and the steel panel to allow them to
deflect without interference. Distances given in the above
diagram are for guidance. Please ask if in doubt.
* Always check edge distances to suit concrete grade and reinforcement.
† Dimension does not allow for bow flares, berthing angles or other
effects which may reduce clearances.
If the tensile load exceeds the rated reaction then tension
chains may be required. Please ask for advice on the
design of tension chains.
Standard manufacturing and performance tolerances apply. Refer to Design and Testing Manual. M1100-S01-V1-3-EN © Trelleborg AB, 2013
