The analysis of existing methods of water use when applied galvanic coatings in the automobile transport sector. It is established that under the existing schemes of water use in the galvanic production wastewater after cleaning goes into the sewer, keeping the risk of contamination of open reservoirs. In such circumstances, the most effective is the use of system of the closed water cycle, which with the help of automatic control allows to take into account changes in the concentration of substances laundered in the washing baths providing the required quality of washing parts with a minimum consumption of water resources.

The article discusses the possibilities of using forklift trucks (stacker-reach trucks) for mechanized installation of dividing walls, when cast-in-place slabs are assembled or manufactured. It is emphasized that in the early 1980s similar equipment that didn’t have a series production, was used in the construction of buildings by the lift-slab method. Some technical characteristics of the old equipment and modern warehouse equipment are compared, the advantages of the modern are revealed. It is noted that the simultaneous use of warehouse equipment on several floors of the erected frame building can lead to a significant reduction in the construction time. It is also indicated that the stacker-reach trucks used at the construction site are multifunctional, since they can not only transport construction cargo but also serve as an auxiliary equipment for safe work at a certain altitude when performing welding operations and fixing joints.
