Abstract

See full text

A method for forming a guide for a top drive unit includes connecting a lower track member to a lower mast section and connecting an upper track member to an upper mast section and telescoped with the lower track section. A slider is slidably positioned about the upper track member so the slider is movable along the upper track member. The slider has a lateral cross-sectional profile substantially the same size and shape as a lateral cross-sectional profile of the lower track member. The skate is slidably positioned about the lower track member to be movable along the lower track member and onto the slider. The skate travels along the upper track member via the slider. The skate is connectable to a top drive unit so the top drive unit is movable along the lower track member and the upper track member.
