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
