DESCRIPTION

The object of the invention relates to a compact hydraulic slewing ring.

As is well known, the term “slewing ring” in the mechanical field refers to a large-scale rolling-element bearing designed to transmit rotary motion from one mechanical component (fixed part, such as a crane structure or the fixed base of a rotary table) to another mechanical component (mobile part, such as a crane arm, its rubber-tired wheel carrier, or the upper part of a rotary table).

The slewing ring has therefore become a consolidated and established mechanical device capable of withstanding radial loads, axial loads, and tilting moments resulting from its specific applications.
