Description
Предметом изобретени вл етс .механизм дл автоматического перемещени противовеса стрелового крана при изменении момента от вееа груза и стрелы.The subject of the invention is a mechanism for automatically moving the counterweight of the boom crane when the torque changes from the weight of the boom and the boom.
Известные того же пазначени устройства, выпол1 енные в виде подвижной но наклонной направл юи1ей , несущей противовес, тележки , перемещаемой канато,;, закрепленным соосно с улиткой, огибаемой грузовым канатом крана, обладают тем недостатком, что не могут реагировать на изменени момеита, возникаюнию вследствие подъема и онуеканн стрелы.The devices of the same meaning, made in the form of a movable but inclined direction carrying a counterweight, of a trolley being moved by a rope, fixed coaxially with a cochlea, bend around the cargo rope of a crane, have the disadvantage that they cannot react to changes in momeite caused by lifting and one arrow.
В описываемом ниже нзобретсиии этот иедостаток устраиеи телг, что канат, закренлеииьи па соосио с улн1т ой блоке, охватьизает блок, прикренле1Н1ЫЙ к тележке нротивовеса , и закренлеи на стреле.In the description below, this deed and the rest of the cable, that the rope, close to the coaxial side with the upper block, covers the block attached to the counterbalance cart and the arrow on the boom.

At the same time, the distance between the counterweight and the axis of the edge varies so that the weight of the counterweight remains equal to the moment of the weight of the lifted load and stretch.
