A heavy duty trailer hitch for coupling a trailing vehicle to a towing vehicle comprising: a tapered sleeve means rigidly secured to said haulage vehicle and having an extended tapered portion with an enlarged bellmouth opening at one end thereof and a reduced dimension opening at a second end thereof; said bellmouth opening having opposed faces diverging outwardly from said extended tapered portion, a winch means positioned adjacent said tapered sleeve means and including a cable drum being rotatably supported at said second end of said tapered sleeve means; a cable means having one end thereof extending through said second end of said tapered sleeve means and being windable on said cable drum, said cable means having a second end extendable outward through said enlarged bellmouth opening of said tapered sleeve means; means to wind up said cable means on said cable drum; and a trailer connector means secured to said second end of said cable means and having tapered faces thereon adapted to nest within said tapered portion of said tapered sleeve means in a complementary orientation and including spaced stop means having limited abutting surfaces to abut complementary spaced portions on said opposed faces of said bellmouth opening to provide a predetermined non-binding, nesting penetration of said trailer connector means into said tapered sleeve means wherein a coupling pin is installed to retain said trailer connector means in said nesting relationship with said tapered sleeve means in a rigid towing assembly and further adapted to be outwardly extensible from said tapered sleeve means whereby said trailer connector means may be coupled to said trailing vehicle by unreeling said cable means from said cable drum to position said trailer connector means in a coupling orientation with said trailing vehicle and thereafter said trailer connector means is drawn into the nesting relationship with said tapered sleeve means by reeling in said cable means on said cable drum whereby said bellmouth serves to guide said cable means, and said trailer connector means into said tapered sleeve means to provide said rigid towing assembly.
