Popis: The article deals with the advantages and disadvantages of cable backhoe excavators in comparison with the hydraulic ones. It was stated that the main cause of the slow performance of rope excavators was a rigid attachment of the bucket to the handle. The authors of the article conduct the synthesis of the structure of rotation mechanism of the bucket, which does not require additional drive. The authors also developed the design of cable excavator bucket rotation mechanism where the bucket rotation is carried out with the help of additional kinematic connection of variable length between the bucket and the handle or the bucket and the boom and implementing the internal forces due to the mutual arrangement of the boom and the arm. The authors consider the trajectory of the working process, where the rotation of the handle is carried out relative to the boom while turning the bucket relative to the handle. The parameters of the mechanism influencing the position of the bucket during the digging relative to the horizon are stated. The authors report the algorithm of search optimization of rotation mechanism geometrical parameters providing the required law of the bucket rotation with the given constraints.
