    Assembly, which is particularly strained and vulnerable to failures is the mining system of multibucket excavators, especially the buckets and the bucket wheel. The paper presents a strength analysis of bucket wheel at the assumed, required performance. The analysis was conducted for the various categories of land, for a specified number of buckets, velocities and power of transmission system. This issue is particularly important at changing the mining conditions and possibilities of increasing efficiency while maintaining the required stability. An analysis of the forces encountered during excavation was conducted. The total resistance of the mining, cutting resistance torque and power at the assumed resistance of the mining efficiency were determined. These data are included in the carried out strength calculations according to PN-G-47000-2 standard, which allowed to assess the applicability of the assumed productivity.
