Pulling Force Limitations
When determining the amount of pulling force required through
the LineTamer, consideration must be given to the amount of drag
on the pipe. The amount of drag can be negligible or more than
the safe pulling strength of the pipe, depending on the terrain
and conditions at the job site.
Nominal pulling force through LineTamer.
3" pipe = 1,250 lbs
4" pipe = 1,800 lbs
5" pipe = 2,000 lbs
6" pipe = 2,400 lbs
Total Force = N Friction
NOTICE:
Total pulling force should never exceed the pipe
manufacturer's safe pulling strength. Exceeding these pulling
forces can damage both pipe and equipment. It may be
necessary to include a force monitoring device or a fusible
link to ensure safe pulling forces are maintained. Slings
and ropes should be of a load rating in excess of the loads
noted above. Do not exceed the rated loads of any pulling
assembly.
