ARTICULATED SUPPORT FOR A HANDLING APPARATUS SUCH AS A CRANE, AND FORESTRY TRACTOR COMPRISING A CRANE ROTATING ON SUCH AN ARTICULATED SUPPORT FIXED ON A TRACTOR CHASSIS

摘要

The invention relates to a support (10) for a handling device such as a crane (3), articulated support intended to be fixed on a mobile frame (1) such as a forest tractor chassis, support comprising: • a platform (20) defining a main plane, • a plate (30) intended to support the handling device, the plate being secured to the platform by means of a first ball joint (40) comprising a ball (41) secured to the platform and cooperating with a ring (46) fixed under the plate so that a center of the ball forms a center of rotation of the ring on the ball, and • anti-rotation means to prevent rotation of the ball. ring on the roture along an axis perpendicular to the plate. The support according to the invention is characterized in that the anti-rotation means comprise a flange (50) of which: • a first end (51) is secured to the ring (46) of the first ball joint connection, • a second end ( 52) is secured to the platform (30) via a second ball joint (60). The invention also relates to a tractor comprising an articulated support as described below.
