FIELD: mining.

SUBSTANCE: group of inventions relates to ground-engaging equipment, in particular, to a ground-engaging tool of bucket equipment. Ground engaging tip comprises a ground engaging portion and a coupling portion. Coupling portion includes an interior surface, a side wall, and an interlock tab. Interior surface defines a coupler pocket and has a base wall. Side wall and base wall define the coupler pocket. Interlock tab has a base end and a proximal end. Base end of interlock tab is contiguous with the side wall, and the interlock tab extends from the base end to the proximal end. Sidewall defines a retention orifice. Ratio of a first distance, measured from the centre of the retention orifice to the base wall and a second longitudinal distance, measured from the centre of the retention orifice to the proximal end is about 3:2 or less. Ground-engaging tool system includes a ground-engaging tip, a clutch and a locking mechanism.

EFFECT: technical result higher durability of the ground-engaging equipment system.
