Which factor requires a larger horsepower motor?

• A. Drive Unit
• B. Horsepower Requirement
• C. Power Transmission
• D. Chairlift Operation Inspection

Answer: (B)

The motor size is driven by the actual horsepower needed to move the load at the desired speed. If the system must haul more weight (more riders, heavier loads) or operate on a steeper incline, it requires more power to overcome gravity, friction, and drivetrain losses. That need for more energy is what dictates a larger horsepower motor.

The drive unit and the power transmission must be able to handle the horsepower that’s required, but they don’t set that requirement by themselves—the load and operating conditions do. Chairlift operation inspection is a maintenance activity and doesn’t determine motor size. So the factor that requires a larger horsepower motor is the horsepower requirement itself.
