ABSTRACT:
A jacking crane supported by four telescoping hydraulically powered legs is used to erect a two spaced apart parallel column drilling derrick. Each column is composed of a number of identical column sections which are assembled on site using the jacking crane which is supported in the space between the columns. The two parallel columns are erected by the jacking crane lifting sections one on top of the other. As soon as these newly added sections are secured to the previous sections, the legs of the jack which are supported from column sections are actuated to move the platform of the jack upwardly where it is attached to an upper portion of the partially completed columns and the legs are then released and then raised to a higher point where they are again attached. The crane lifts additional sections and is "walked-up" by stages between the two partially completed columns until the columns reach the desired height.
