UNDER-CRANE PATH OF PROTECTIVE SHELL OF NUCLEAR POWER PLANT Russian patent published in 2022 - IPC B66C7/00 

FIELD: mechanical engineering; transportation.

SUBSTANCE: invention relates to the field of mechanical engineering and transportation, namely to under-crane paths of a protective shell of NPP. The under-crane path of the protective shell of the nuclear power plant contains console supports uniformly installed along the circumference and fixed at one level on an inner side of the protective shell with a gap to each other, and a rail installed on top of console supports, made in the form of circumference with a radius of the under-crane path and connected to console supports with fasteners. Each console support is made of upper and lower horizontal plates installed in parallel to each other, fixed to each other with vertical longitudinal and transverse ribs. Plates and transverse ribs are fixed with one end in a reinforced concrete structure of the protective shell, side slots are made at ends of plates, facing the protective shell, from both sides, and a protrusion is made in an upper part of the end of the console support, from a side opposite to the protective shell.

EFFECT: increase in the reliability of an under-crane path of a protective shell of NPP.
