The purpose of the work is to increase a capacity of a single-bucket excavator at the expense of bucket shape improvement. The improved bucket design offered will allow scooping a large soil volume without hydraulic drive characteristics changing. The effect mentioned is achieved at the expense of a cylindrical shape of a bucket rear wall. There is presented a design diagram of forces affecting an improved bucket. The computations of the improved bucket of the excavator based on tractor UMZ-6AKL allowed drawing an outline for the supposed design and obtaining dependences of a resistance moment on the bucket during scooping upon the angle of a bucket turn.
The dependences of the resistance moment for the buckets with the volume of 0.25; 0.35; 0.45; 0.55; 0.65 m 3 .
The improved design of the bucket will allow increasing the volume of soil scooped. In such a way, the increase of the capacity of single-bucket hydraulic excavators without hydro-drive characteristics changes is achieved.
