Abstract
A suspension structure is disclosed for use in running well hardware such as a pumping assembly by cable into a well and pulling the hardware from the well, the structure including two suspension masts. One of the masts is a lightweight mast having a working height sufficient to suspend the hardware above a well platform or the like on which the masts are mounted but not having a load capacity sufficient to withstand the forces required to pull the hardware from the well. The other mast is a short mast of high-load capacity capable of withstanding such forces but not of sufficient height to suspend the hardware. The two masts are used alternatively for running and pulling operations.
