[TowerTalk] TowerTalk Digest, Vol 35, Issue 48

[Jim Smith]

Take another look at the Thern website where they talk about pulling and 
lifting.  http://www.thern.com/basics.php?loc=main&section=2  It appears 
that when they talk about pulling a load they are talking about the 
weight of the load, which is, of course, at right angles to the 
direction in which the load moves.

This would explain the derating applied to use with an inclined plane.

No expert on this.  I just read what they said on the site.
