Mobile bearing 8 is connected with the lever 5 through a flexible rod 10, providing interaction of the lever 5 with the movable support 8 through the bypass unit 11 mounted on the frame 1. Flexible rod 10 zapasowa to bypass the block 11 and the fixed ends on the lever 5 and the movable support 8.The mechanism works as follows.In h is by the overturning moment about the axis of attachment of the hinge arm 5 to the frame 1 (Fig. 1). Component of the specified time through the slider 6 moves the object 4 from the horizontal to the vertical position relative to the axis of the hinge connection 3 of the frame 1 and the object 4, and the slider 6 is moved in the guide rails 7, and the movable support 8 is moved in the guide rails 9 by means of the efforts transmitted flexible shaft 5 (Fig. 2). The stability of the object 4 in a vertical position provided by the position of the RAM 6 in the guide 7, the maximum length of the lift cylinder 2 and the tension of the flexible rod 10, and the position of the movable support 8 in the guide 9 (Fig. 2).The translation of the object 4 in a horizontal position is in the reverse order. Initial position (Fig. 1) is provided by the horizontal component of the weight of the object 4 and the length of the lift cylinder 2. The lifting mechanism of the long-length object in the upright position, containing a frame, a lifting hydraulic cylinder, one end of which is pivoted on the frame, a hinge connection object with a frame and a lever, one end of which is hinged to the frame, and the second on the RAM that is installed in the mounted object guides, characterized in that the hinge connection of the object with the frame placed on the movable Sol on the specified lever, which is connected with said movable support by a flexible rod, zapasovany through the bypass unit and the fixed ends to the lever and the movable support.
