    • A method of fabricating a tall multi-stage work piece. A vertical shaft is provided extending below ground at a permanent fabrication facility. An elevator platform is provided in the shaft. The elevator platform is adapted to lower a work piece into and lift the work piece out of the shaft. At least one above ground work station is provided at the upper end of the shaft. A work piece is placed on the elevator platform. The elevator platform is then lowered as each stage of the work piece is completed, in order to maintain a desired working height for workers at the above ground work station. The elevator platform is raised and the work piece is removed from the elevator platform, when fabrication is complete.
    • 一种制造高级多级工件的方法。 在永久性制造设施处提供在地下延伸的竖直轴。 在轴上设有升降平台。 电梯平台适于将工件降下并将工件从轴上提升出来。 地面工作站至少有一个位于轴的上端。 工件放在电梯平台上。 随着工件的每个阶段的完成,电梯平台被降低,以便为上述地面工作站的工人保持所需的工作高度。 当制造完成时,升降机平台升起,工件从电梯平台移开。
