Which device controls chairlift movement in correct directions?

• A. Call/Send Devices
• B. Slack Cable Safety Device
• C. Footrest Switches
• D. Obstruction Device

Answer: (A)

The control that directs the chairlift to move in the intended direction is provided by the call/send devices. These stations at the bottom and top let riders or operators request the chair’s movement toward a specific end, and the drive system responds to those requests to advance or return the chair accordingly. In other words, they serve as the command inputs that determine which way the chairlift travels.

Safety devices like the slack cable safety device, footrest switches, and obstruction devices play crucial roles too, but they protect and monitor the system rather than directing movement. The slack cable device guards against cable slack conditions, footrest switches ensure rider position and readiness, and the obstruction device stops motion if something blocks the path.
