The paper is a continuation of the issue of the technical solution of a mast type jib crane for handling sludge pumps. It serves for the use in Building no. 900, Block V2, of the nuclear power plant Jaslovské Bohunice. It is an optimization of the original, in-service damaged handling device with manual control of lift and rotation. The overloading of the device has an insignificant effect on the lifting force on a crank handle. It was found that the lifting force permanently falls within the recommended range of 120 to 160 N for convenient operation by a single worker. Inasmuch as there is a complete absence of bearings in the slewing gear in the original design, it is the solution to this issue that is the subject of the paper. The problem of pulling out the sludge pumps, which was established in the course of using the jib crane, ingeniously provided the opportunities to further design changes on the original design. The solution offered was to scrap the original design of the carrier inserted into the support and replace it with a fixed mast on which the boom would rotate. Accordingly, it would potentially be feasible to increase the load capacity of the jib crane, and thus the issue of the sludge pumps attached to the tank bottom would be solved. Moreover, it is attainable to extend the scope of this crane in this way.
