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

1. Braces

2. Straps

3. Supports

4. Tie downs

The correct answer is: Tie downs

When considering the prevention of the machine bedplate from lifting on one end as the elevator starts or stops, the use of tie downs is essential. Tie downs are specifically designed to secure an object in place, providing stability during movement or operation. They can effectively keep the bedplate anchored and prevent dynamic movements that could cause it to lift. By using tie downs, you create tension and restraint that counteracts any forces acting on the machine bedplate during the start-up or stopping phases of the elevator. This ensures that the machine remains stable and operational, reducing the risk of mechanical failure or safety hazards associated with misalignment. While braces, straps, and supports may provide some level of assistance, tie downs offer a more direct method to counteract lifting forces specifically during the critical moments when the elevator is starting or stopping. This tension mechanism is crucial in maintaining the integrity and alignment of the machinery, contributing to smooth and safe elevator operation.
