Изобретение относитс к подъемно транспортному машиностроению, а именнр к стреловым кранам с телескопической / башней, и может быть использовано как грузоподъемное устройство.The invention relates to a lifting machinery industry, and specifically to telescopic / tower jib cranes, and can be used as a lifting device.

Известно грузоподъемное устройство, содержащее стрелу, шарнирно закрепленную на вьщвижной секции телескопической колонны, установленной на основании, гидроцилиндр; расположенный внутри теле скопической колонйы и соединенный с выдвижной секцией, на которой закреплен блок, охваченный органом, один конец которого закреплен на основании, и элемент креплени стрелы, шарнирно j соединенный со стрелой fl Недостатком известного устройства вл етс сравнительное неудобство его эксплуатации.A lifting device is known, comprising an boom hinged on a sliding section of a telescopic column mounted on a base, a hydraulic cylinder; located inside a telescopic colony and connected to a sliding section, on which a block is fastened, covered by an organ, one end of which is fixed on the base, and a boom fixing element hinged j connected to a fl boom.

Цель изобретени - повышение удоб- ства эксплуатации устройства.The purpose of the invention is to improve the usability of the device.

Цель достигаетс тем, что .устройство снабжено ползуном с направл ющей, за- кре.плен ой с внешней стороны телескоп -The goal is achieved by the fact that the device is equipped with a slider with a guide, which is stored on the outside of the telescope.

ческой колонны, а затем креплени стрелы представл ет собой упор, шарнирно соединенный с ползуном, на котором также закреплен другой конец гибкого орга- на.A boom column and then a boom attachment is an anvil hinged to a slider on which the other end of the flexible body is also attached.

На чертеже изображено грузоподъемное устройство, общий вид.The drawing shows a lifting device, a general view.

Claims

The lifting device comprises a boom 1 hinged on the sliding section 2 of the telescopic 3 mounted on the base 4. The hydraulic cylinder 5 is controlled from the command station 6, is located inside the column 3 and is connected to section 2, on which the block 7 is engulfed by a flexible organ 8, the ends of which are fixed on the base 4 and the slider 9, co1C) with the guide 1O located on the outer side of the column 3. The fastening element of the boom 1 is a stop 11 that is connected to the boom 1 and the slider 9. On the boom 1 there is a bar y zoo-gripping body 12. Lifting device works: in the best way. When lifting hydraulic section 5 sections Z of column 3, boom 1 and slider 9 are raised, which results in a change in the lifting height of the load gripping body 12. The lifting device just in a constructive relationship allows changing the lifting height of the load, it is convenient to use and easy to maintain, in general, improves the convenience of its operation. Claims of Invention A lifting device comprising an boom, an uiapHHpHif fixed to an intermediate section of a telescopic column mounted on a base, a hydraulic cylinder; located inside the telescopic column connected to the mobile section, on which the block is fastened, covered by a flexible organ, one end of which is fixed to the base, and the boom fastening element pivotally connected to the boom, characterized in that it is equipped with a slider to increase the ease of operation on the outside of the telescopic column, and the boom mounting element is a stop pivotally connected to the slide, the other end of the flexible member is also attached to KOTqpOM.
