Figure 4— Three Phase Lift Set where all three wires
are lifted at once.
Figure 3— Wire Tongs, lever lift, link stick, and rope
blocks used on heavy conductors.
NOTE:
(1) Supports
• Maximum recommended load for Saddles with exten-
sions is 800 lbs.
• Lever Lift will exceed Wire Tong strength when load is
properly applied in line with pole
(2) Working Loads
• Any elevated structure requires an analysis in deter-
mining the load
• When calculations are impractical or unnecessary, and
a pole is slightly higher than neighboring poles, con-
sider total weight of span on each side as maximum
working load
• Does not apply to hilltop structures where special
analysis must be made to determine load
• When working load is greater than that given in the
table for a particular Wire Tong, it will be necessary
to use double Wire Tongs with double-type lever lift,
or use larger Wire Tong
(3) Epoxiglas® Working Loads
• Maximum working loads are based on a pole deflec-
tion of approximately one inch when used in man-
ner shown
• Cantilever values, with a safety factor of more than
two, are: 1-1/2” – 375 ft.-lb.; 2” – 900 ft.-lb.; 2-1/2” –
1500 ft.-lb.; and 3” – 2500 ft.-lb.
• Tensile strength values, with a safety factor more
than two, are: 1-1/2” – 1500 lb.; 2” – 2000 lb.; 2-1/2”
– 2500 lb.; and 3” – 3000 lb.
