Shaft steelwork-conveyance interactions are present in the literature on the subject avail-
able in Poland, these problems have been extensively studied by the research teams from
AGH-UST, the Central Mining Institute and the Silesian University of Technology. Despite
novel and original solutions in this field, fresh problems tend to appear which have to be solved
promptly. In this context an attempt to determine the force of steelwork-conveyance interac-
tion due to irregularities of the guiding string might prove useful in the strength analysis of
the conveyance or the shaft steelwork.
This study attempts to determine the steelwork-conveyance interaction force and carrying
elements stresses based on the dynamic analysis of the hoist operation, taking into account the
irregularities or misalignment of the guiding string and their random occurrence. To validate
the model some experiment on a real object were done.
