Transcript Ker-Thob Installation

A new solution
for an old problem…
Does your mine have
this problem? If it
does, you need to get
the Ker<><Thob
implemented into
your roof control
plan!
Ker<><Thobs can be put directly over beltlines.
Ker<><Thob
Application
&
Installation Process
Any steel pipe, stronger than the roof bolt can be used
with the Ker<><Thob, as long as it’s inside diameter is
between (2.125 to 2.6 inches for our 2 1/8 inch unit) or
(2.25 to 3 inches for our 2 1/4 inch unit).
One miner can carry a
temporary roof jack, a
shoulder bag containing
a few Ker<><Thobs,
two channel locks, and
a selection of pipe cut to
different lengths. This
is all that is needed to
allow one man to repair
several loosened roof
bolt plates.
Make the area
safe before
proceeding to
install the
Ker<><Thob.
Install
temporary
supports!
Do not work
under
unsupported
roof.
Raise the loosened
roof plate up to
the roof and
measure the
distance from the
plate to the flange
of the bolt head.
Subtract two inches
from the measurement
to get the correct
length of pipe needed
to be used with the
Ker<><Thob.
(5”– 2” = 3”)
pipe length needed
Select the
precut pipe
from the
shoulder bag.
Set the split
halves of the
Ker<><Thob
onto the flange
of the bolt head.
Make sure
that the
notched
ends of the
split halves
are resting
on the
flange of the
bolt head!
Slide the spacer
pipe over the
bolt head and
the split halves.
Start the
nut up over
the bolt
head and
thread onto
the split
halves.
Push the
spacer pipe
against the
split halves to
aid in the
threading of
the nut onto
the unit.
Grasp the
notched
end of the
split halves
while
tightening
the nut.
Two
Channellock
Pliers (one 420
and one 460),
and a tape
measure are the
only tools needed
for the
installation of a
Ker<><Thob!
The Ker<><Thob
was tested by
MSHA on 10/3/96
and 9/3/97. Both
times it was
subjected up to
60,800 pounds of
pressure with no
failure.
