Abstract:
In combination;a roadway trailer having a pair of spaced generally parallel side frames and a floor secured between said side frames;a coiled tubing rig mounted on struts on said trailer for movement between an operable position for the injection of coiled tubing in a borehole and an inoperable stored position for transport; said coiled tubing rig including a coiled tubing reel mounted on said trailer for rotation of said reel and having a pair of opposed spaced end flanges for retaining the coiled tubing on the reel, a mast mounted for pivotal movement on a rear end of said trailer and having a pair of spaced longitudinally extending parallel mast posts, and an injector mounted on said mast for injecting coiled tubing in the borehole;said mast posts being spaced from each other a distance greater than the length of said coiled tubing reel between said end flanges, said mast posts when moved to stored position on said trailer fitting alongside said end flanges and receiving said reel therebetween thereby to minimize the projecting height of said mast on said trailer when in stored position;mounting means adjacent a rear end of said trailer mounting said mast for pivotal movement;each of said side frames having a rear end section including upper surfaces inclined upwardly from said rear end, said mast posts when moved to a stored position being supported on said upper surfaces.
