A tubing injector unit for use in inserting and withdrawing coiled tubing from a well bore hole having in its structure a tubing injector component, a gooseneck component and a mounting component for connection of the overall unit to a supporting structure such as a mast. The mounting component has an upper area for carrying the gooseneck component thereon and a lower underside area forming an injector component supporting structure. The unit in operation thereby supports the injector component in a suspended condition beneath the mounting component so that the working forces which develop in inserting and withdrawing tubing in a bore hole are transferred separately to the mounting component by the injector component and the gooseneck component and thus directly to the supporting structure by the mounting component.
