Abstract

L'invention concerne un élément d'usure comprenant : une patte supérieure ayant une surface de mise en prise avec le sol sur un côté externe de celle-ci et une surface de montage sur un côté interne de celle-ci, et une patte inférieure espacée de la patte supérieure et ayant également une surface de mise en prise avec le sol sur un côté externe de celle-ci et une surface de montage sur un côté interne de celle-ci. Les surfaces de montage définissent une cavité de montage entre elles et les pattes se rejoignent au niveau d'une partie avant; la patte supérieure définit (i) une ouverture de verrouillage en son sein, (ii) un bord arrière, et (iii) un élément de levage situé de manière adjacente à l'ouverture de verrouillage et le bord arrière et entre ceux-ci; l'élément de levage définit (a) une surface avant inférieure à la surface de mise en prise avec le sol de la patte supérieure et est incliné par rapport à celle-ci, (b) une surface de support inférieure opposée à la surface avant, et (c) une surface de mise en prise arrière s'étendant entre la surface avant et la surface de support inférieure et étant en retrait par rapport au bord arrière; la surface avant, la surface de support inférieure et la surface de mise en prise arrière formant une partie rétrécie autour de laquelle un dispositif de levage peut être situé pour repositionner l'élément d'usure.
