This is TWIN

Our breakthrough TWIN elevator system delivers unrivalled efficiency in buildings 50 metres and higher – by using two passenger cars operating independently in the same shaft.

With TWIN, both cabins use the same guide rails and landing doors. Each car is equipped with its own traction drive, controller, ropes, counterweight and governor.

An intelligent Destination Selection Control (DSC) system gets people to their destination faster by grouping together individuals travelling to the same floor. TWIN also boasts a TÜV-tested safety concept to satisfy even the most stringent requirements.​

TWIN is the perfect mobility solution for buildings with regular inter-floor traffic: offices, hotels and even hospitals.

Happy 20th birthday to our TWIN elevator

As the first and only elevator to have two cabins operating independently in the same shaft, TK Elevator is celebrating this momentous milestone by highlighting what makes TWIN so special – its space-saving capabilities, greater energy efficiency, and capacity to transport more passengers as compared to conventional elevators.

With TWIN elevators located on four continents, this innovative system continues to push the boundaries on what’s possible for urban mobility.

Watch how TWIN still moves beyond standard elevator concepts even 20 years later.

Key Benefits

Exceptionally cost-effective

Two lift cars share the same hoistway, landing doors and guide rails, saving substantial money in construction labour and materials, as well as in maintenance.

Comfortably up to 40% more traffic

TWIN's double-car configuration means your mobility system can now easily handle up to 40% more passengers.

Highly energy-efficient

When passenger volumes are low, TWIN parks one cab to save on energy while the other car stays in operation. An optional energy recovery function feeds about 30% of the recovered braking energy back into your building’s power grid.

Impressively space-efficient

TWIN maximises your leasable space by reducing the number of shafts required to effectively service your buildings.
