Abstract: The present invention provides an improved cantilever (10) for skidding on a platform (30) of a drilling rig. The cantilever (10) has two longitudinal members (12) while an edge (32) of the platform (30) has two transverse members (14,14a). The longitudinal and transverse members are connected at each interposition by a sliding and swivel assembly (20, 20a, . . . 20d). Each sliding/swivel assembly (20, 20a . . . 20d) is connected by an actuator (24, 24a) to the longitudinal or transverse member so that the cantilever (10) is operable to be displaced on the platform (30) by translation, rotation or a combination of translation and rotation.
