FIELD: salvage equipment. ^ SUBSTANCE: invention may be used to rescue people in emergencies, for instance in case of fire in high-rise building. Device comprises rope interacting with fixed sliding roller providing for the main support, and "grid" made of crosspieces laid onto rods of U-shaped bracket. Device is equipped with base in the form of T-shaped profile. Holes are made in base wall with the possibility of fixation to clasp. Axis of hole is arranged in plane passing via middles of rods and parallel to them. On plane of base there is a fixed roller, where chute for rope and holes are made to fix ends of U-shaped brackets, at least two, arranged back-to-back along rope. At the other side of plane there is a fork fixed, between adjacent teeth of which there is a central part of rounded section of U-shaped bracket. ^ EFFECT: proposed device makes it possible to continuously evacuate large groups of people in critical situations; to do braking on non-loaded branch, which considerably improves conditions of operation; to quickly release the rescued as soon as landed; to provide for circular use of rope or cord, by connection of branch ends; to use opposite branch to control lowering in case of self-rescue; to remove rounded rope aside to provide for landing in safe area. ^ 3 cl, 7 dwg |
