Abstract

Изобретение относитс  к подъемно-транспортному машиностроению, а именно к опорным устройствам стрел автокранов. Цель изобретени  - повышение надежности. В стойки 1 вмонтированы гидроцилиндры, штоки 6 которых несут опоры 3. Между опорами 3 и упорами 11 стоек 1 установлены пластины 5, соединенные ст жками 8. При подъеме стрелы при технологическом осмотре автокрана на штоках 6 креп т пластины 5 дл  исключени  самопроизвольного опускани  стрелы. 3 ил.FIELD OF THE INVENTION The invention relates to hoisting and transport machinery, in particular to supporting devices of booms of truck cranes. The purpose of the invention is to increase reliability. Hydraulic cylinders are mounted in racks 1, the rods 6 of which carry supports 3. Plates 5 are mounted between supports 3 and supports 11 of racks 1 and connected by straps 8. When lifting the boom during the technological inspection of the crane, 5 plates are attached to the rods 6 to prevent spontaneous lowering of the boom. 3 il.
