The present invention relates to a method and apparatus for the servicing or workover of a hydrocarbon well. The apparatus includes a pair of hydraulic cylinders pivotally mounted to a pair of base beams connected to each other. The cylinders are moveable from a horizontal position for transportation to a vertical position for operation in which position the two cylinders flank a wellhead and are adapted to lift the wellhead and attached production tubing using a workover beam and a lifting sub. The wellhead and production tubing can be rotated as or after they are elevated. A motor may be mounted to the workover beam to rotate the wellhead and the tubing. A calibrated pressure gauge may be used to indicate the weight being lifted. The apparatus can be wheel mounted and towed behind a crane truck. The advantage is a safe, economical and time-saving apparatus for performing jobs that previously required the setup and operation of a workover rig.
