WINCH Russian patent published in 2018 - IPC B66D1/36 

FIELD: transportation.

SUBSTANCE: invention relates to hoisting mechanisms, namely to hoists with a traction winch mechanism. Winch can be used to lift and move various loads. Winch consists of a housing, a traction sheave connected to the drive, and a pressing device, a slab movable with respect to the body, on which is mounted a traction sheave and a clamping device. Clamping device consists of a double-armed lever, on the one side of which a pressure roller is mounted, and on the other side there is a support platform for interacting with the fixed stop located on the housing. Bypass block can be installed on the movable plate, and the traction organ in the guide grooves is laid in such a way that the running branches from the pulley grooves are incident on the guide rails of the additional block and vice versa.

EFFECT: technical result of the claimed winch is to increase the reliability and simplify the design of the winch operation by reducing the number of parts, providing open access to structural elements, facilitating the laying of the rope on the traction sheave, and also by providing the possibility of laying the rope from any of its points.
