Which stand is associated with an electric pump mechanism to raise lamps?

• A. Cinevator
• B. Roadrunner
• C. Rocky Mountain Leg
• D. Umbrella Stand

Answer: (A)

Stands with an electric lift are built to raise the light head using a powered pump, giving quick, controllable height changes on set. The Cinevator stand is designed with that electric pump mechanism, so it can lift lamps without manual cranking. The other options are primarily manual or purpose-built for different uses: Roadrunner and Rocky Mountain Leg emphasize stability and heavy-duty support rather than an integrated electric lift, and Umbrella Stand is meant for holding umbrellas or light modifiers, not raising lamps. So the Cinevator stand is the one associated with an electric pump mechanism to raise lamps.
