ABSTRACT:
A wellhead puller is positioned in a support on an excavated well exposing a wellhead cover having mounting nuts positioned thereon. A threaded shaft having first and second ends is mounted for vertical movement in the support with the first end extending above the support and the second end which contains the puller extending downwardly near the wellhead cover. The puller has a cross piece mounted thereon with two rigid legs extended downwardly therefrom, each leg of which has a right angled foot extending therefrom adapted to fit under and engage a loosened wellhead cover. A tightener is mounted on the first end of the threaded shaft above the support for elevating the shaft and the puller attached thereto for lifting the wellhead cover from the top of the well. The right angled feet are slotted to fit under loosened mounting nuts of the wellhead cover or are trapezoidal to engage the underside of a loosened cover.
