When aligning machinery, why is it important to perform vertical alignment first?

Performing vertical alignment first is critical because it simplifies the alignment process. When adjusting machinery, vertical alignment often sets a stable reference point for subsequent adjustments, particularly for horizontal alignment. By establishing proper vertical positioning, technicians can ensure that equipment components, such as shafts or pulleys, are at the correct vertical height before addressing horizontal positioning. This sequential approach reduces the complexity of the alignment task and minimizes the chances of misalignment that may arise when attempting to adjust both vertical and horizontal positions simultaneously.

Achieving vertical alignment first can also help in identifying other alignment issues that might not be as apparent when only assessing horizontal alignment. Once vertical alignment is confirmed, it becomes easier to focus on achieving precise horizontal alignment, ensuring overall machine efficiency and performance.
