What devices would you use to prevent the machine bedplate from lifting on one end as the elevator starts or stops?

The ideal choice to prevent the machine bedplate from lifting on one end during the start or stop of an elevator is tie downs. Tie downs are specifically designed to secure equipment in place, providing stability and resistance to movements that could occur during operational changes such as acceleration or deceleration.

In the context of elevator systems, tie downs help maintain the alignment and position of critical components, including the machine bedplate. This is crucial for ensuring proper functioning and safety, as any unintended movement can lead to mechanical issues or compromise the system's integrity.

While mounting brackets, support beams, and stabilizers may each contribute to the structural integrity of the installation, they do not specifically address the dynamic forces experienced by the machine bedplate during elevator operations in the same way that tie downs do. Thus, tie downs are the most effective choice for this particular application.
