La liaison châssis/tourelle. On ne saurait évoquer les porte-grues sans consacrer deux lignes à ce point combien important et délicat. En effet, ce rôle de liaison, et donc de transmission des efforts incombe à la seule couronne d'orientation et à son mécanisme d'entraînement. Là encore on compte deux écoles principales : celle de ceux qui soudent le porte-couronne sur le châssis; la couronne est alors boulonnée ou goujonnée sur le porte-couronne et celle de ceux qui boulonnent directement le porte-couronne sur la plaque de base. 2, record 1, French, - roulement%20%C3%A0%20billes%20de%20couronne%20d%27orientation
