Presently the hoisting installation operated in the Wieliczka Salt Mine is mostly used for transporting visitors to the underground mine sections. It comprises two elevators which are able to effectively transport groups of up to 42 people during a single ride. Design objectives developed prior to its mounting at the shaft bottom and observations made by maintenance engineers clearly indicate that the guiding system in the shaft is very stiff and so deformations are in fact negligible. The components of the guiding system which have the highest stiffness are bunton beams, designed in accordance with pertinent regulations having relevance to hoisting installations.To verify the rationale of implementing the stiff steelwork frame, the digital model of the steelwork frame was created and numerical procedures were applied, taking into account the maximal design loads and operational loads. Numerical results were validated through measurements of real stress values at selected components of the guiding system in the hoisting installation operated in the shaft “Regis’, under variable operating conditions. The analysis of measurement data allows a preliminary evaluation of structural parameters of the car frame, highlighting the potential of reducing the mass of components selected to be optimised.
