A coiled tubing transport unit includes a coiled tubing reel unit, a guide sleeve coupled to the coiled tubing reel unit, and a corresponding arm coupled to the coiled tubing transport unit, wherein the arm is retractable or extendable from the guide sleeve, and a hydraulic cylinder coupled between the coiled tubing reel unit and the transport unit. The arm retracts or extends from the guide sleeve when the hydraulic cylinder is actuated to push or pull against and move the coiled tubing reel unit along a length of the coiled tubing transport unit.

A coiled tubing transport unit includes an injector head affixed to the coiled tubing transport unit at one or more movable mount points, and at least one actuator mounted between the coiled tubing transport unit and the injector head, wherein the actuator is configured to move the one or more movable mount points and the injector head in a longitudinal direction along a length of the transport unit.

A coiled tubing transport unit includes a coiled tubing reel unit, a first mechanism for shifting the coiled tubing reel unit lengthwise along the coiled tubing transport unit, an injector head, and a second mechanism for shifting the injector head lengthwise along the coiled tubing transport unit.
