The challenge

In high-rise buildings, space is everything

Skyscrapers are a key element of urban life. People in megacities spend most of their time living and working in high-rise buildings — and the main challenge in these buildings is space.

Elevators need to occupy less space and transfer more people in less time. That is hard to achieve given the growing demands of urban life.

The solution

Same shaft. Bigger car.

Kledelmans has developed a new elevator car arrangement that expands the available car area in group elevators — bringing time and cost benefits for heavy passenger traffic in residential and commercial buildings.

The car area increases by a minimum of 30% up to 60% without changing shaft dimensions. The design can be used for new elevator installations as well as for modernization projects — and the building area is saved.

Project cases

Proven on real buildings

Project 1

High-rise residential

In a standard arrangement, the building has six elevators with 1000 kg capacity. The new arrangement delivers four elevators with 1600 kg capacity — without changing current shaft dimensions.

~40 m²saved per floor
≈2000 m²saved in a 50-floor tower

Elevator capacity increases without changing shaft dimensions, while passenger traffic is handled in the best time manner.

Project 2

Residential building converted to offices

Due to limited area, the architect could provide only two passenger elevator shafts (5800 × 1900 mm). The vertical transportation consultant required at least four passenger elevators of 1000 kg each.
