What is the requirement for automatic leveling in hydraulic elevators?

Automatic leveling in hydraulic elevators is essential for ensuring a smooth and safe transition for passengers when entering and exiting the elevator. The requirement for 2-way automatic leveling indicates that the elevator can automatically adjust its position in both directions: lowering and raising to accurately align the cab floor with the landing floor.

This feature enhances passenger safety by reducing the risk of trips and falls due to misalignment. The 2-way system can respond effectively to the variability of the landings and the weight load in the elevator, allowing the cab to maintain an accurate position whenever it arrives at a landing.

In the context of hydraulic elevators, this requirement reflects industry standards for safety and functionality, prioritizing user experience and consistent operation.
