Abstract
Cette invention concerne un système de pic pour haveuses et machines de forage. Ce système comprend un pic muni d'une queue cylindrique qui peut être insérée amoviblement et de façon rotative dans un alésage cylindrique d'un porte-pic, son immobilisation axiale étant assurée au moyen d'une bague de verrouillage. Celle-ci est adaptée sur une bague de portée qui est elle-même montée à rotation sur le décolletage de la queue du pic. La bague de verrouillage est constituée par une bague écrasable telle qu'une bague torique pressée contre la paroi cylindrique du logement de réception. Un agencement de ce type est utilisable notamment sur les machines de creusement et d'abattage.
