Abstract: Based on the review of leading manufacturers of grabs, features of bucket buckets for excavation work are presented. It is determined that, in general, the resistance of the ground to cutting is the largest fraction. Having agreed to consider the initial ground surface as flat, and the current trajectory of cutting as circular, the dependence of the soil resistance on digging from the angle of rotation of the jaw of the grapple is determined by the formulas of Dombrovsky-Goryachkin and A. Zelenin. Numerical comparative analysis of these formulas is carried out.
Keywords: grab, bucket, cutting, soil.
