FIELD: machine building.
SUBSTANCE: method of fork lug (18) manufacturing for hoisting devices with, in principle, horizontal in the work position fork blade (5), and adjacent to it via fork bend, in principle, vertical fork back (20), that is equipped with connecting elements (2, 3) for transportation devices, at that fork lug contains several connected parts means that at least some parts are welded with each other. At that parts of the fork lugs are welded by means of the electronic beam welding and/or laser welding. Weld between the adjacent surfaces of the parts is made from both sides over surface to minimum depth 15 mm.
EFFECT: increased lug strength.
