ELEVATOR CABIN MOTION CONTROL ASSEMBLY (VERSIONS) Russian patent published in 2012 - IPC B66B5/04 B66B1/26 

FIELD: transport.

SUBSTANCE: proposed assembly 20 comprises pulley 18, first weight, second weight, and detachable joint between said weights. Pulley 18 revolves at the speed corresponding to that of elevator cabin. Said first and second weights are coupled with pulley 18 at first and second points of turn spaced radially from pulley rotational axis. Connector that ensures inelastic joint between said first and second weights inhibits turn of weights at pulley angular speeds lower than the first speed and allows their turn at speeds higher than said first speed. Said connector comprises magnetic connector furnished with first element to be displaced by first weight and second element to be displaced by second weight. Note here that first element comprises permanent magnet while second element includes magnetic material.

EFFECT: higher reliability.
