FIELD: mining industry.
SUBSTANCE: group of inventions relates to the mining industry, in particular to ground-engaging tools for ladles. Ground engaging tip comprises a ground engaging portion and a coupling portion. Coupling portion is in opposing relationship to the ground engaging portion along a longitudinal axis. Coupling portion includes an interior surface defining a coupler pocket, and an interlock tab extending along the longitudinal axis in a direction away from the ground engaging portion. Interlock tab terminates at a proximal end and has an inner and outer lateral surface. Inner lateral surface has a proximal planar portion and a concave portion. Proximal end of the interlock tab has a proximal end width measured along a lateral axis from the outer lateral surface to the proximal planar portion. Concave portion has a radius of curvature greater than the proximal end width. Ground-engaging tool system comprises a ground-engaging tip and a clutch.
EFFECT: technical result is an increase in the durability of the equipment.
