Patent FR-2313230-A1 (FR)
IPC: B60P1/64
Filed: 1976-06-03
Abstract: An inner loading arm component (3) of the device can be pivoted about a tilting axis (5). A first section (2a) of an outer loading arm component (2) can be displaced telescopically in the inner loading arm component (3), it being possible to block the said first section (2a) in the extended position by means of a stop (8) which can be drawn in. At the free end of the inner section (2a), an outer section (2b) of the outer loading arm component (2) is pivotably mounted. At the outer section (2b), a hydraulic cylinder (10) which is supported on the supporting surface (1) engages. In the extended position of the telescope, a hook (7) which engages in an eyelet (13) on the container (11) prevents the outer loading arm component (2) from bending. Therefore, the container can be tilted about the tilting axis (5). In the drawn-in position of the telescope, the bending movement of the outer loading arm component (2) serves to set down and pull up the container (11). In the bent position, the telescope is automatically blocked by the engagement of a second hook (9) in an engagement element (14). By means of this design, both types of movement of the container can be carried out with a single hydraulic cylinder, which reduces the constructional outlay.
