FIELD: salvage operations.
SUBSTANCE: ladder for evacuation of people from premises of multistory buildings and structures, comprising safety devices in the form of braking devices 11 with an endless rope 12 and made of two flexible side guiding branches 8 at one end, which have clasps for its fixation, and at the other end - there are transverse crosspieces-steps 9 threaded at side guiding branches of the ladder at the equal distance from each other through holes made at the end of crosspieces and fixed on side guiding branches against downward slippage in the unfolded working condition, besides, it is made was wound and unwound onto a reel made of sides 6 rigidly connected to a shaft 5, on which a bracket 7 is rigidly mounted with attached side guiding branches 8 with fixed tubular crosspieces-steps 9 by means of threaded fixators 10 screwed into end parts of tubular crosspieces-steps, at the same time the shaft 5 of the reel, together with the sides 6 is made with the possibility of rotation on a tubular axis 3, rigidly installed in side brackets, which in their turn, are rigidly attached to a base 1 and in the upper part are additionally connected to each other for stability by a rigid connection, at the same time a jacket 20 is hingedly fixed to the base, consisting of hingedly fixed parts that cover side brackets when closed and the ladder wound on the reel to form a closed portable reservoir.
EFFECT: improved quality and structural characteristics of ladders used for individual salvage of people from premises of high-rise buildings and structures in case of emergency situations and convenience of their usage in specified buildings and structures.
