Adjusting machines laterally for alignment is best accomplished using horizontal jack screws because they provide precise control for fine-tuning the positioning of heavy machinery. When machines are misaligned, precision in adjustment is crucial to ensure optimal performance and prevent wear on components. Horizontal jack screws can easily be threaded in or out to raise or lower one side of the machine, allowing for adjustments that make lateral corrections without requiring excessive force or heavy lifting tools.

In contrast, other methods, while useful for different situations, may not provide the same level of control or ease of alignment. Hydraulic lifts are generally used for lifting and lowering rather than precise lateral adjustments, vertical jacks primarily provide elevation without lateral movement, and adjustable mounts are often used during initial installation rather than for ongoing adjustments. Therefore, horizontal jacks crews are specifically designed to achieve the necessary lateral alignment effectively.
