Wire Tong Applications
The following information is intended to assist in the
selection of the proper Wire Tongs for a particular
application and greatest load. Four popular
application methods are shown on these pages.

tong band on lift stick.

*Based on Tong “B” substantially horizontal. The lower the top saddle is placed below the conductor level, the greater the strain
on Tong  “A” and therefore the less load it can support.

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.
