Real easy.
Somebody bought the old telephone company line truck and converted it to a spudder rig for well drilling.
Axel mounted across the rear winch was used as a capstain to raise and drop the bit by the driller applying and letting go of tension on the bit line wrapped around the wheel.
It's a home made version of how to rig a 2½ ton with rear winch for well drilling from an old version of the US Army manual of well drilling.
