CRANE HOOK UNIT Russian patent published in 2014 - IPC B66C1/34 

FIELD: transport.

SUBSTANCE: invention relates to hook suspensions for a crane. Crane hook unit contains pulley casing including pulleys, elongated areas each one of which has through hole, and casing frame with locking surface, crossbar having multiple brackets each one of which has a hole. Bracket has multiple surfaces matching multiple angles of relative position between casing and the first crossbar. Multiple surfaces match locking surface and form gap between them for each set of angles, shaft rotatably inserted into holes of elongated areas of casing and multiple brackets, deadlock made capable to be inserted into gap between locking surface and any of multiple surfaces to prevent pulley casing from moving relative to crossbar. Stabiliser can be mounted with possibility to rotate between two brackets. Limit stop is installed between two brackets to prevent its rotation by angle greater than 90° relative to crossbar when it stands vertically. The stabiliser contains flat area which naturally contacts with ground when the crossbar lays horizontally on ground to stabilise pulley casing in vertical position during reeving.

EFFECT: improvement of hook unit design to make it easier to reeve ropes and stabilisation of parts during cargo lifting.
