Our one-of-a-kind TWIN passenger elevator is the industry’s first system with two independent cars, one on top of the other, in one shaft. It gives you the same conveyance capacity in 25% less space. It also lets you introduce brand-new traffic concepts while setting a new standard in high performance.

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. Delivering efficiencies across the board.

Key benefits

Extremely cost effective

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

Up to 40% more traffic

Its double-car configuration means now your mobility system can 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

By reducing the number of shafts required to effectively service your buildings over 50 metres in height, TWIN maximizes your leasable space.
