FIELD: transport.
SUBSTANCE: invention relates to devices for chuting people and cargo under action of gravity, in particular to life saving equipment for self-evacuation during fires and for descending mountain-rescue men and spidermen. Device for gravitational chuting people and cargoes includes body, flexible load carrier made as resilient steel band placed on drum, movable and immovable pins between which the load carrier is moved. According to the invention the device contains speed limiter located between two immovable pins and consisting of plank set on axis, right and left pins located on the plank at different sides from axis, rod with piston which rod is shifted down by left pin, spring squeezed by piston and bolt serving to adjust spring flexibility. To stabilise speed the device additionally contains a gear set transmitting rotation from drum to gear wheel interacting via balancer axis with pendulum and pendulum weight, herewith the balancer can also be of spring type.
EFFECT: improved safety of device for gravitational chuting people and cargoes at constant speed in automatic braking mode.
