when raising a lee c. moore and most jacknife derricks you have to tail them in the last couple of feet by tieing the forklift onto the geronimo or some such line, this line is usually tied to the derrick on the drillers side, leave the forklift tied to the line while pinning, start pinning the derrick on the off driller side, if one off the pins doesnt line up you can pull on the derrick with the forklift to adjust this, if you pin the drillers side first pulling on the derrick does no good
