Description

Стойка 2 пойериетс против Часовой Стрелки и через тросовую отт жку 5 Поднимет стрелу 1. Блок 12 крюковой подвески при этом останетс почти на том же уровне, так как ветви грузового троса И сократ тс , а блок 12 онуститс . Опускание стрелы 1 происходит при выпуске жидкости из штоковой полости гидроцилиндра 7 из-за сил т жести стрелы 1 и груза, а при необходимости - и путем нагнетани жидкости в поршневую полость. При этом блок 12 будет подниматьс за счет удлинени троса 11 уравнительного полиспаста.Hour 2 will work against the Slow Hour and pull the boom through the cable lanyard 5. The hook suspension unit 12 will remain almost at the same level, since the branches of the cargo cable I will shorten and the weight loss 12. The lowering of the boom 1 occurs when the fluid is discharged from the rod end of the hydraulic cylinder 7 due to the force of gravity of the boom 1 and the load, and, if necessary, by injecting fluid into the piston cavity. In this case, the block 12 will rise due to the lengthening of the cable 11 of the equalizing polyspast.
Предлагаема схема подвески стрелы позвол ет устранить воздействие изгибающего момента от силы т жести груза на конструкцию стрелы и сделать ее существенно легче. Уменьшаетс и вертикальное перемеш,ение груза при подъеме стрелы, что снижает расход энергии на подъем стрелы.The proposed boom suspension scheme makes it possible to eliminate the effect of the bending moment on the force of the weight of the weight of the load on the boom design and make it substantially easier. The vertical mixing of the load when the boom is raised also decreases, which reduces the energy consumption for boom lifting.
Экономический эффект от внедрени изобретени в среднем составит 300 руб. в год на одну машину.The economic effect from the implementation of the invention is on average 300 rubles. per year per car.
