What is the driving mechanism type used for lifts?

• A. Winding Drum
• B. Roped Hydraulic
• C. Direct-Plunger Hydraulic
• D. Slack-Chain Device

Answer: (A)

The driving method for lifts is typically a winding drum arrangement. In this setup, a motor turns a large drum, and ropes are wound around or unwound from the drum to raise or lower the car. One end of the rope is attached to the car (and often another to a counterweight), so as the drum rotates, the rope length changes and moves the car up or down. This arrangement is simple, robust, and widely used, with a brake and governor to control speed and ensure safety.

Hydraulic options exist, such as roped hydraulic or direct-plunger hydraulic, but those use fluid pressure to move the car rather than a rope-wrapped drum driving the motion. The slack-chain device isn’t a typical driving method for lifts.
