What connects the pre-wired harness to the travel cable block?

• A. Hoistway Limit Switches
• B. Drive Types
• C. Platform Control Wiring
• D. Pump Motor

Answer: (C)

The connection from the platform’s pre-wired harness to the travel cable block is made through platform control wiring. The harness on the platform carries all the control signals and interlock information needed for safe operation—things like run direction, speed, start/stop, and safety sensors. As the platform moves, these signals must travel with it, so they feed into the travel cable block, which routes them between the moving parts and the stationary controls. This wiring interface ensures the platform controls stay synchronized with the drive and safety circuits as the escalator moves. Other options relate to different components or concepts (safety switches along the hoistway, the overall drive method, or a motor type) and do not define the actual connection point between the platform harness and the traveling cables.
