Источники информации, прин тые во внимание при экспертизе 1.ABTOjpcKoe свидетельство СССР № 540322, кл. В ббс 13/12, 1975. This section is provided with a shaft 3. The longitudinal channels 4 from the highlander shaft 3 are closed by plugs 13. On the housing 1 a hydraulic motor 14 is mounted, which is connected to the ZG shaft 3 in the lower part by means of a mechanical transmission 15 and connected to the 1T gvdromotor 17 for livodg mechanisms of gyu rosopathic organ. The motor 17 is connected to channels 4 by means of sleeves 18. Case 1 is connected to a boom 19 of a crane. The device works as follows. The energy source (not shown) is connected to the cargo body 16 through the pipes 9, the side channels 7 of the Shugs; niQno: these 8 sleeves, side channels 5 of the shaft, longitudinal channels 4 and sleeves 18. Shaft 3 receives rotation from the hydraulic motor 14. Thanks to sealing rings 10-12, nozzles 9 can move from the housing 1, and the sleeve 6 to the housing 1 and the shaft 3. Phase 6 is held 6 tons round. In the case of deformation or biennial of the shaft 3, its upper part can be moved relative to the sleeve, and the sleeve and the sleeve 9 can move relative to the body 1, which increases the reliability of the device. The invention of the Device for the supply of energy to the lifting body of the crane, containing the cylinder; 14 casing, in which a shaft is installed on the under-heads, made with longitudinal channels that are connected in the upper part of the shaft with the side channels of the shaft located at different levels relative to each other, as well as branch pipes and additional rings The reason is that, in order to improve its reliability in operation, it is equipped with plugs and a sleeve, which is located in a cylinder case on the upper part of the shaft and is filled with side channels and internal annular cavities located in response to the side channels sedynennymi a and the side channels of the sleeve, P {ri this pshotnitelnye ring mounted mkkpu spigots and the body, between the sleeve and the casing and between the sleeve and the shaft, the longitudinal channels with the shaft end stoppered patrz ki rigidly connected with the side channels gnpzy.
