TWIN - a double-car elevator system from TK Elevator

825 ft (250m)

1,200 fpm (7 m/s)

4,000 lbs (1,800 kg)

Two independent cars in one shaft

Our breakthrough TWIN passenger elevator system features two cars, operating independently in the same hoistway, increasing usable building space.
intelligent Destination Selection Control (DSC) gauges traffic demand and groups riders based on destination for increased efficiency.
Whether used in new buildings or as part of a modernization project, TWIN can transport up to 40% more passengers.

Requests are always distributed by the destination selection control so elevator cabins do not obstruct each other and a minimum distance is always observed.
If the safety distance is breached, the emergency stop system shuts down the drives, activates the brakes and triggers an emergency stop for both elevator cabins.
Safety levels are monitored by an independent control system, giving TWIN the highest safety classification of Safety Integrity Level 3 (SIL3).

TWIN drastically cuts labor and materials expenses because the elevators share a single hoistway, guide rails and landing doors. TWIN pays dividends for years to come.
Unlike a double-deck elevator system, TWIN can park one cab while the other stays in operation, saving energy when passenger volumes are low.
Our advanced regenerative drive feeds unused energy back into the building, so you save money and use less power.
