Abstract
Une machine de havage de reef est divulguée, comprenant un support mobile, généralement monté sur des chenilles; un cadre de lancement; et un ensemble tête de havage s'étendant à partir du cadre de lancement, vers et dans le gisement à haver pour définir une cheminée. Le cadre de lancement est incliné par rapport au support, pour incliner l'ensemble tête de havage à l'angle correct afin d'aligner l'ensemble tête de havage avec l'angle du gisement à haver. Dans un mode de réalisation, le cadre de lancement (et l'ensemble tête de havage) est monté transversalement au support, de telle sorte que le cadre de lancement et l'ensemble tête de havage s'étendent à angle droit par rapport au support mobile. Dans un mode de réalisation, l'ensemble tête de havage comprend en outre une tête de havage extensible (relativement plate) comportant des stabilisateurs latéraux pour venir en contact avec les parois latérales de la cheminée havée, des vérins de poussée étant prévus pour déplacer la tête de havage à distance et vers le corps de poussée, lors de l'utilisation.
