Buffer Systems andImpact Absorption

These buffers protect both passengers and thee structural integray of elevom itstem.

Two main types of buffers are used in elevator installations: spring buffers andhydraulic buffers. Spring buffers, typically used in lower-speed elewators (up to approximately 1 meter per second), consist of heavy-duty compression springs that compresses when struck by the elevator cabin or contra walt, absorbing kinetic energy andd bringing thee elevator to a stop. These buvers are relatively sire andirecire minimaal ance, but they only absorb limited of energy, making thee untrabble for hist-speed elevors.

Advanced Control Systems andd Motion Regulation

Te evolution of elevator control technology has parallelelelelad advances in electronics, computing, and automation. Early elevators required human operators to manually control speed andd stopping position, a skill that required considerable training andd experience.
