When staggering T-rails, what orientation should be used?

When staggering T-rails, the correct practice is to orient one side with the groove up while placing the other side with the tongue up. This configuration is essential for proper alignment and structural integrity. The groove and tongue method ensures that the rails lock together more effectively, preventing any vertical or lateral movement that could compromise the system's stability and safety. This staggered approach helps distribute the load evenly across the rails, minimizing the potential for wear or failure.

Using this specific orientation also aids in maintaining a smooth operation within the elevator system, ensuring that the mechanism functions correctly and reduces the likelihood of malfunctions. Adopting a random installation or using the same orientation for both ends could lead to increased wear and potential safety hazards, compromising the elevator system's functionality and reliability.
