BRAKE BUFFER SYSTEM TO PREVENT FALL FOR HIGH-SPEED SHAFT ELEVATOR Russian patent published in 2016 - IPC B66B5/22 B66B5/24 

FIELD: machine building.

SUBSTANCE: present invention relates to braking buffer anti-falling system for high-speed shaft elevator. System comprises brake cable (2) fixed on both sides of cabin (5). One end of brake cable (2) is fixed on top of shaft (6), and other end of brake cable (2) is fixed at bottom of shaft (6). At cabin (5) bottom there is lever mechanism (11). On top of brake cable (2) there is buffer (1), and at bottom of brake cable (2) there is tension connector (4). At cabin (5) bottom there is safety mechanism (3) of above braking cable fixed on brake cable (2) and connected to lever mechanism (11). Buffer (1) comprises smooth safety mechanism (8) of brake cable with buffer rope (9) connected with brake cable (2). On buffer rope (9) there is clamp (10) of buffer cable. System is easily installed, damping force of brake cable is constant and controlled.

EFFECT: system performs braking function to prevent fall, considerably improves safety of high-speed operation, directed non-rigid guide rail, and also increases safety of high-speed operation of elevator shaft.
