FIELD: mining industry.
SUBSTANCE: invention relates to the mining industry, in particular to ground-engaging tools for ladles. Ground engaging tool system comprises a ground engaging tip. Ground engaging tip includes an interior surface with a coupler pocket having an opening. Interior surface has a base wall and a first and second side wall. Tip defines a first and second coupler face walls having a planar portion and a curved portion. Planar portion is adjacent the base wall, and the curved portion adjacent the opening. Ground engaging tool system includes a coupler movably connected to the ground engaging tip between a nominal position and a maximum rotated pitch position. Coupler includes a mounting nose with a first and second exterior face surface and is within the coupler pocket. Between the nominal position and the maximum rotated pitch position, the curved portion coupler face walls are in non-contacting, spaced relationship with the coupler.
EFFECT: technical result is an increase in the durability of the ground-engaging tool.
