Which component is checked for plumb, level, and square after placement?

• A. Mast Installation
• B. Support Arms
• C. Hoistway Travel Check
• D. Weight of Units

Answer: (B)

After placement, you verify alignment with plumb, level, and square to ensure the structural member that directly positions and secures the unit is true. The support arms are the connectors that carry the unit and keep it aligned with the rails and hoistway. If they aren’t plumb, level, or square, the car can sit off-axis, causing uneven wear, rubbing against components, misaligned doors or comb plates, and potential safety issues. Mast installation deals with the vertical alignment of the mast itself, hoistway travel checks focus on travel clearances and positioning, and the weight of units relates to load rather than how the unit sits in place.
