Description
шем подъеме стрелы преодолеваетс как сос . тавл юща силы т жести противовеса 10, так и усилие деформации пружины 14, стрела плавно выходит в вертикальное положение , инерционное запрокидывание стрелы исключаетс .This boom lift is overcome as sos. The pressing force of the weight of the counterweight 10, as well as the force of deformation of the spring 14, the boom smoothly goes to the vertical position, the inertial dropping of the boom is eliminated.
При эксплуатации крана стрела, как правило , сохран ет посто нное положение относительно обоймы 4, положение ее центра т жести относительно башни 1 определ етс только углом наклона стрелы, поэтому предлагаемое устройство обеспечивает достаточно надежное уравновешивание стрелы,During operation of the crane, the boom, as a rule, maintains a constant position relative to the yoke 4, the position of its center of gravity relative to the tower 1 is determined only by the angle of the boom, therefore the proposed device provides a sufficiently reliable balance of the boom
При наращивании крана, когда стрела, установленна в вертикальное или близкое к нему положение, выдвигаетс в обойме 4, положение ее центра т жести относительно башни соответственно не измен етс или измен етс незначительно; при выдвижении стрелы смещени упорной тележки 8 не происходит , контакт ее ролика 9 со стрелой сохран етс , соответственно противовес 10 сохран ет посто нное положение, и уравновешивающий изгибающий момент не измен етс .When increasing the crane, when the boom installed in a vertical position or close to it, is advanced in the holder 4, the position of its center of gravity relative to the tower does not change or change slightly; when the boom extends, the thrust carriage 8 does not move, its roller 9 keeps contact with the boom, respectively, the counterweight 10 maintains a constant position, and the balancing bending moment does not change.
