[TowerTalk] Come-along recommendation needed

[sabrams at nycap.rr.com]

If you read the materials that come with the come-along you will see that 
the rating is for pulling dead weight; i.e. dragging 2 or 4 thousand pounds. 
The force on the come-along is the coefficient of drag/friction needed to 
move the object.  It is NOT rated for lifting those weights where the full 
force of the 2 tons is on the cable.  73  Saul  K2XA
