  • Patent number: 7249629
    Abstract: A mobile vehicle for inserting jointed pipe into a well, having a derrick and hydraulic rams to raise and lower same, adapted to conduct additional operations which will allow a well to be completed by this vehicle alone. Three winches are provided, a first to raise and lower power tongs to manoeuvre and thread jointed pipe, a second situate on the bed of the vehicle to raise and lower jointed tubing, and a third likewise mounted on the bed of the vehicle on which a conductive wireline is wound, for raising and lowering logging and swabbing devices in the well. Levelling jacks are provided at four corners of the vehicle to permit levelling of the vehicle and alignment of jointed pipe with the borehole of the well. Each of the rams, power tongs, levelling jacks, first, second, and third winches are hydraulically powered, preferably by a single pump, as each of the aforementioned devices are not operated at the same time but sequentially.
