(54) | Rotation device for working units in lift trucks or the like |
(57) The present device is provided with conceptually new means which allows an angular
displacement of the fork-carrying or tool-carrying plate, which means are very advantageous
in comparison with the known solutions as the conventional system of rotation on ball
bearings is no longer necessary. In general, such means comprises a rotation device (1) which is obtained by a fixed element or casing (2) on the rear side of which there are fixing clamps (2') which are to be coupled with corresponding front clamps (3) which are fixed to the self-moving lift truck. The fixed element or casing (2) is provided with a hollow seat in which a crown (4) is inserted. The crown (4) represents the rotating part on which an outer fork-carrying unit is mounted. A supporting plate (5) is included in the fork-carrying unit. |
