ELEVATOR CATCHER Russian patent published in 2017 - IPC B66B5/20 

FIELD: machine building.

SUBSTANCE: catcher is installed on elevator (100a) load lifting device (2a) and comprises braking device (300), which interacts with load lifting device (2a) rail conductor (7). Braking device (300) comprises disc cam (55) capable of turning about axis, which is for activation of catcher is induced to turn on turning angle leading to activation. Due to rotation on turning angle leading to activation disc cam (55) comes in contact with rail conductor (7), due to which rail conductor (7), displacing at load lifting device (2) moving relative to catcher, turns disc cam (55) into position, in which braking device (300) and, thus, catcher create provided braking action relative to rail conductor (7). Catcher actuates electrically controlled activation mechanism (45) with activation lever (47) installed with possibility of turning and activation spring (52), which in case of necessary, via activation lever (47) results in disc cam (55) rotation on leading to activation turning angle. Elevator contains said catcher. Catcher actuating method includes stages, leading to disc cam contact with rail conductor.

EFFECT: invention enables reduced power consumption.
