Live-Line Work Minimum Approach Distances
Distances agree with OSHA
guidelines in Table R-6 of the
Federal Register published
1/31/94. These distances
take into consideration the
highest switching surge an
employee will be exposed to
on any system with air as the
insulating medium and the
maximum voltages shown.
The clear live-line tool dis-
tance shall equal or exceed
the values for the indicated
voltage ranges.
*Avoid contact.

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

WORKING LOADS FOR CHANCE WIRE TONGS*
NOTE:
(1) SUPPORTS Maximum recommended load for Saddles
is 800 pounds. The Lever Lift will exceed the strength of
Wire Tongs when load is properly applied in line with the
pole.
(2) WORKING LOADS Any elevated structure requires
an analysis in determining the load. When calculations are
impractical or unnecessary and a pole is slightly higher
than neighboring poles, it may be sufficient to use the total
weight of the span on each side as the maximum working
load. This does not apply to hilltop structures where special
analysis must be made to determine the load.
When the 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 a
larger Wire Tong.
(3) EPOXIGLAS
®
WORKING LOADS The maximum
working loads given for Epoxiglas Wire Tongs are based on
a pole deflection of approximately one inch when used in the
manner shown. The cantilever values, with a safety factor of
more than two, are: 1

Wire Tongs
Chance Wire Tongs have many applications for moving and holding live conductors clear of the
working area, for flat crossarm and/or ridge pin-construction, on horizontal post insulator struc-
tures, all types of suspension insulator lines, as auxiliary arm braces, and in EHV construction
for brace pole or ladder positioning guides.
A whole family of clamps, attachments, saddles and lever lifts allow the wire tongs to be adapted
specifically to the mechanical requirements of various maintenance jobs.
Chance Wire Tongs are made with Epoxiglas
®
poles. The castings are made of heat treated alu-
minum alloy, separated by bronze wear rings.
The wide range jaws on the head can be clamped tightly on the conductor by turning the stick from
a position beyond the minimum working clearances (see page 2202). A large head is available on
two sizes of tongs where extremely large conductors are encountered.
