Ratcheting tie-downs vs come-alongs?

I'm trying to use a ratcheting tie-down as a comealong to move an
aircompressor to a trailer.

I'm finding that as the webbing builds up on the ratcheting barrel, it
will eventually interfer with the prawling mechanism. This limits the
distance the tie-down can pull to about 3 feet. Useless.

I've taken up as much excess as I can at the load end, but the barrel
still fills too quickly.

Any suggestions or am I using the wrong tool for the job? - MIke
