The article presents a variant of improving the design of the working equipment of a single-bucket excavator. The proposed technical solution allows the development and sampling of solid and frozen soil without changing the working equipment from the bucket to the hydraulic hammer. The result is achieved by installing two hydraulic hammers on the front part of the bucket. Presents calculations of the hydraulic system of the excavator and hydraulic hammers, allowing to confirm the performance of the proposed solution. The methodology of technological operations is determined taking into account the use of the proposed technical solution.
