MSHA PROGRAM POLICY MANUAL VOLUME V
75.605 Clamping of Trailing Cables to Equipment
Section 18.40 requires insulated strain clamps or cable grips on
the trailing cables of permissible machines, except that mesh-wire
cable grips (e.g. Kellems grips) are not permitted on trailing
cable reels. Where mesh-wire cable grips are permitted, they
shall be installed in accordance with the following:
1. Sufficient slack shall be provided in the trailing cable
between the machine and the cable grip.
2. A hose clamp shall be provided on the outby end of the
cable grip to prevent slippage along the cable jacket.
A length of flame-resistant hose conduit is acceptable for
insulating a metal strain clamp.
75.606 Protection of Trailing Cables
Trailing cables shall be placed away from roadways and haulageways
where they might be run over or damaged by mobile equipment.
Where the method of mining requires that trailing cables cross
roadways or haulageways, the cables shall be securely supported
from the mine roof, or if the height of the coal seam does not
permit hanging the cables, the cables shall be installed in a
trench cut into the mine roof or mine floor. A substantial bridge
for the equipment to pass over the cables is also acceptable if,
in the opinion of the inspector, the cables are adequately
protected.
