What does the system do during an earthquake?
The P-wave is detected
The first wave of an earthquake is usually the non-destructive P-wave. When the elevator senses this wave, the system switches to seismic mode without any human intervention.
Cabin and counterweight in opposite directions
Before the destructive second wave arrives, the cabin and counterweight move in opposite directions to balance the system. This reduces the dynamic load on the guide rails.
Safe stop at the nearest floor
The elevator is programmed to stop at the nearest floor. The doors open and passengers are evacuated before the destructive wave arrives.
The building shakes, the system stands firm
The 125-millimetre guide rail eliminates the risk of buckling under horizontal oscillation. Reinforced brackets, anti-derailment emergency guides and intermediate bases placed between the counterweights preserve structural integrity.
Calculation-based strength
Strength calculations are performed taking into account the seismic design acceleration coefficient of the region.
125 mm Guide Rail
The risk of buckling under horizontal oscillation has been eliminated.
Reinforced Brackets
The strength of brackets and load-bearing systems has been increased.
Anti-Derailment Guides
Emergency guides have been developed for the cabin and counterweight frames.
Heavy-Gauge Suspension
Sheet thicknesses in the suspension systems have been increased.
Intermediate Bases
Rigidity is ensured by placing intermediate bases between the counterweights.
Rope & Cable Protection
Measures are in place to prevent ropes and cables from snagging inside the shaft during an earthquake.
