Abstract

The bucket can be lifted from its work position, during which it is immediately above the front axle of the vehicle, as far as the maximum height while its inclination w.r.t. a horizontal axis remains unchanged. It can move forward and downward while its initial position w.r.t. a horizontal axis remains unchanged and can also tip forward by rotation w.r.t. a horizontal axis. The third movement is obtained by expansion of an hydraulic jack whose shaft (17a) is attached to the top edge of the bucket (1) and whose cylinder (17) is pivoted horizontally on a brace which comprises a pair of L-shaped arms (2).
