Efter placering af koblingshovedets overpart 1 på kuglen 13 trykkes bøjlen 7 ned til vandret position, hvor den låses til bøjlen 8 ved hjælp af en låsepind 12. Ved denne bevægelse af spændegrebet føres spændekæberne 4 ind under og omkring kuglen 13 og halsen 14, hvor-5 ved der opstår et træk af koblingshovedets overpart 1 ned mod kuglens centrum, samtidig med at der opbygges et tryk mellem spændekæberne 4 og undersiden af kuglen 13 af en sådan størrelse, at friktionen mellem kuglen og koblingshovedet fastlåser de to komponenter indbyrdes. Som en ekstra sikkerhed mod vertikal vinkeldrejning ju-10 steres de fire stilleskruer 5 til berøring mod den cylindriske hals 14. Denne justering foretages en gang for alle, når koblingshovedet anvendes på samme anhængertræk.After placing the upper part 1 of the coupling head on the ball 13, the shackle 7 is pushed down to the horizontal position where it is locked to the shackle 8 by means of a locking pin 12. In this movement of the clamping grip, the clamping jaws 4 are inserted under and around the ball 13 and the neck 14, 5, there is a pull of the upper part 1 of the coupling head down towards the center of the ball, while at the same time creating a pressure between the clamping jaws 4 and the underside of the ball 13 such that the friction between the ball and the coupling head interlocks the two components. As an added security against vertical angular rotation, the four adjusting screws 5 are adjusted to contact against the cylindrical neck 14. This adjustment is made once and for all when the coupling head is used on the same towbar.
