<p>A hooking and stabilising device for a lift work platform, comprising: a support body (2), predisposed for associating to a work platform (30) rotatably about a first rotation axis (X1) and for constraining to an end of a lift arm which can displace the work platform (30) between an initial position and a determined work position; a double-acting hydraulic cylinder (3), provided with a base (4), solidly constrained to the support body (2), which closes two chambers separated from one another by a sliding piston constrained to a stem (5) associable to the work platform (30) rotatably about a second rotation axis (X2) parallel to the first rotation axis (X1). The chambers of the cylinder (3) are in mutual fluid communication via a conduit along which a check valve (6) is arranged. This check valve (6) is predisposed to assume an open configuration, in which the chambers of the cylinder (3) are in mutual communication and the work platform (30) can oscillate with respect to the support body (2) about the first rotation axis (X1), and a closed configuration, in which the chambers are not in mutual communication and the work platform (30) cannot oscillate with respect to the support body (2).
