Are the frames on tow trucks reinforced for heavy pulling? I worked building winch trucks but think they were just heavy spec'd. trucks. Winch mounts were bolted and welded. Winches are rated with a bare drum too.
Some triple frame---Winch ratings very on manufacture of unit--a Holmes 750 for instance was
rated on a full spool at 25 tons. Holmes rated all on a full spool, a first wrap on a 750 would have
been 32 ton , but it's pretty rare anyone pays that much rope out, normally on the third or fourth
wrap or more. For the simple fact always want to be in close proximity of what your hooked to.
For something buried/stuck it takes several motions to move it, you want the boom line to pick
weight forcing wheel chocks or stiff legs in the ground and count on deck line to pull it ahead,
which my be only 4 to 5 feet, pull ahead and start the procedure over again. Recovering from
a long distance normally just drags the unit to wreck, plus more cable leaves the chance if a
cable decides to give up the ghost it has much less distance to whip.
