This diploma thesis is a kind of continuation of my bachelor's thesis, which deals with auxiliary equipment for excavators focused primarily on recycling operations, especially crushing of stones, residual concrete, and similar suitable construction waste. Such accessories have certain advantages over their counterparts of other types. The main advantages are their mobility, lower set-up costs, space saving. They are an ideal choice for processing small amounts of construction waste at the point of origin. The use of such recyclates is more economically and environmentally advantageous than the use of primary materials. In this work, a brief overview of the current state of the market with additional equipment for crushing stone and residual concrete is made. According to the specified criteria, the basic parameters of the crushing bucket were selected, from which the further design of the device was derived.
