Does an ERD let the elevator run normally during load shedding?

No. It performs a controlled rescue trip to the nearest landing and opens the doors. Continuous operation requires a building generator or UPS arrangement.

Can an ERD be added to an old elevator?

Often yes, subject to controller and drive compatibility, which we confirm on site.

How often should the ERD be tested?

We test it at each scheduled maintenance visit, and after any work on the drive or controller.

Emergency Rescue Device (ERD) for Elevators in Islamabad

Power interruptions are a fact of life for buildings in Islamabad and Rawalpindi. An emergency rescue device is what keeps an interruption from turning into an entrapment.

When mains power is lost, the ERD uses its own backup supply to move the car slowly to the nearest landing and open the doors so passengers can step out unaided.

How an ERD works

The device monitors the incoming supply. On failure, after a short delay it takes control of the drive on backup power, moves the car at reduced speed in the easier direction of travel, stops it level with a landing and releases the doors. Normal operation resumes when mains power returns.

Where an ERD is especially important

Any building can lose power, but the consequences differ.

Residential buildings and home elevators used by elderly residents
Hospitals, clinics and diagnostic centres
Hotels and buildings with visitors unfamiliar with the premises
Offices and plazas operating outside staffed hours

Fitting an ERD to an existing elevator

Many older elevators can be retrofitted. We check the drive type, controller compatibility and available panel space, then fit and test the device, including a live simulated power-failure test at handover. ERD function is rechecked at every scheduled maintenance visit.
