An injector arrangement for use in a rig has a movable carrier, a derrick tiltably mounted to the carrier, and a trolley capable of sliding along the derrick. An injector cradle is movable along the trolley in at least a plane perpendicular to the derrick and is pivotally mounted beneath the trolley. An injector is supported at its upper end from the cradle. At least two hydraulic cylinders are supported at one end by the derrick and are engaged at an opposed end to a lower end of the injector for rotating and tilting the injector relative to the trolley and derrick.
