01. Improved convenience & comfort
Major key components that are most essential to elevator operation require replacement as age increases the risk of failure or damage.
① Control panel (traction & hydraulic)
Updating the control panel to the latest system allows fine-tuned control of motor speed for smoother transport and landing.
* Some buildings will have different parts.
② Traction machine (traction)
Updating the traction machine can dramatically improve ride comfort and convenience.
③ Hydraulic unit (hydraulic)
Using the latest hydraulic unit can improve ride comfort.
02. Improved safety
No only can we help stop breakdowns and accidents before they happen, we can install basic safety equipment, including advanced safety devices to keep passengers safe in earthquakes.
⑫ Earthquake management equipment
When sensors detect initial micro-motions (P waves) of an earthquake, they automatically bring the elevator to the nearest floor, open the doors, and prompt passengers to evacuate. In weaker earthquakes, the elevator will restart operation automatically after a set time. Also, when they detect major motion (S waves) in a strong earthquake, the doors close and operation suspends until a professional technical personnel can perform a complete inspection.
Even in sudden power outages, the elevator will move to the nearest floor on battery power. After landing, the doors automatically release, then close again after a fixed period to prevent confinement.
This device prevents accidents by instantly activating the dual brakes even if the elevator starts moving with the doors open. The door open/close status and basket position detection device quickly detects that the elevator is moving with the doors open, and the UCMP circuit and dual system brakes, which are separate circuits from the normal circuit, safely stop the elevator. When descending, the gap between the boarding floor and the basket is secured at least 1 m to prevent trapping and pinching, and when ascending, the elevator stops within a gap of 11 cm or less between the boarding floor and the bottom of the cab to prevent falls.
This device is unavailable on some elevator models.
