FIELD: electrified railways.
SUBSTANCE: proposed dropper is made of hinge-connected links. It contains additionally spring elements installed on opposite ends. Each link of dropper is curved and provided with slot. When pairs of links are interconnected, they can be bent only in one direction. In particular case, each link of dropper is made in form of metal curved plate with slots providing easy assembling of links into chain, narrow part of each link being fitted in slot of adjacent link. Each link of dropper can be made nondetachable, provided with additional slot in wall and projection. Spring elements can be made in form of coil springs consisting of two-three turns.
EFFECT: increased service life of suspension owing to use of flexible link dropper featuring reduced wear of articulated links and action on contact wire at passing of current collector, simplified adjustment of height of suspension.
