Claims (1)

Подвижный противовес грузоподъемного крана, состоящего из рычага, закрепленного на шарнире, противовеса, закрепленного на одном плече рычага, канатной тяги, соединяющую стрелу крана с другим плечом рычага, отличающийся тем, что, с целью уменьшения высотного габарита, противовес состоит из двух половинок, закрепленных к двум рычагам, расположенным по бокам поворотной платформы, с целью увеличения момента от противовеса, рычаги шарнирно закреплены к поперечной балке, соединяющей две подвижные тележки, перемещающиеся по ездовым балкам, расположенным по бокам поворотной платформы, имеющие консоли вдоль балок длиной, равными другому плечу рычага и соединенными с плечом рычага полиспастами, имеющими общий канат, объединенным со сбегающей ниткой грузового полиспаста уравнительным блоком из двух роликов так, чтобы две ветви общего каната подходили к трубчатой балке, соединяющих обе консоли, с противоположных сторон, чтобы не препятствовать перемещению тележек по ездовым балкам и не создавать дополнительные нагрузки на тележки, причем рычаги имеют два упора для ограничения поворота от максимального до минимального вылета противовеса относительно шарнира, с целью уравновешивания не только стрелового момента но и грузового, тележки перемещаются по наклонным ездовым балкам с помощью полиспаста, сбегающая нитка которой соединена со стрелой крана, если кран в стреловом исполнении, или с треугольной стойкой маневрового клюва, если кран в башенно-стреловом исполнении, причем тележки перемещаются независимо от величины вылета противовеса относительно шарниров.A movable counterweight of a crane consisting of a lever mounted on a hinge, a counterweight mounted on one arm of the lever, cable traction connecting the arrow of the crane with the other arm of the lever, characterized in that, in order to reduce the height, the counterweight consists of two halves, fixed to two levers located on the sides of the turntable, in order to increase the moment from the counterweight, the levers are pivotally attached to the cross beam connecting two movable trolleys moving along the riding beams, races laid on the sides of the turntable, having consoles along the beams of a length equal to the other shoulder of the lever and connected to the lever of the lever with pulleys having a common rope, combined with a runaway thread of the pulley block with an equalization block of two rollers so that two branches of the common rope fit the tubular beam, connecting both consoles, from opposite sides, so as not to impede the movement of the trolleys along the riding beams and not create additional loads on the trolleys, and the levers have two stops to limit the gates from the maximum to the minimum outreach of the counterweight relative to the hinge, in order to balance not only the boom moment but also the load moment, the carts are moved along the inclined driving beams using a chain hoist, the run-off thread of which is connected to the crane arm, if the crane is in the boom version, or with a triangular shunting rack beak, if the crane is in a tower-boom design, and the trolleys move regardless of the size of the counterweight offset relative to the hinges.
