Abstract: A lift frame for conducting wireline or coiled tubing operations on an oil rig comprises a main frame and a substantially cylindrical lift sub for lifting the lift frame assembly by means of a block. A pivot is provided between the main frame and the lift sub. The lift frame is provided with skids for supporting the assembly in an undeployed position with the main frame being substantially parallel to a resting surface such as a rig floor. In the undeployed position, the lift sub extends vertically upward from the resting surface. When the lift sub is engaged by elevators coupled by links to the lifting block, the lift frame assembly can be raised into a deployed position wherein the main frame pivots relative to the vertical lift sub to be substantially perpendicular to the resting surface. Difficulties in engaging a horizontally-oriented lift sub are therefore eliminated.
