The construction of high-rise buildings has been busily advancing in recent years as construction technology advances. As buildings grow taller, so the need for elevators with larger capacities and faster speeds grows to move more passengers to their destination floors in a single go.

Travel in a high-rise building using a large cpacity / high-speed shuttle elevator

The shuttle elevator moves between the lobby floors at high speed. To travel to their destination floor, passengers transfer to a local elevator on a lobby floor. By linking high-capacity/high-speed shuttle elevators with local elevators, allows for efficient travel within a high-rise building.

Traction machine and brake

Large cpacity shuttle elevators utilize high-output permanent magnet synchronized motors as well as a high-capacity traction machines with two windings. Additionally, through the use of brakes that are only tens of kilograms in weight per machine and caliper electromagnetic brakes that use multiple small brakes, the traction machine has been made smaller and more light weight as well as easier to maintain.

Safety devices

A double-safety method has been used where upper and lower safety devices have been installed to halt the high-capacity/high-speed car in emergencies (conventional elevators use only lower safety devices). This has allowed approximately twice the braking force without increasing the size of the safety devices.

Comparison of cars for 90-person elevator and conventional 15-person SPACELGR II

As elevators grow in capacity, the cars become heavier as more passengers are carried.

Through the use of a honeycomb core floor panels, a high degree of rigidity is maintained while the overall weight of the car is lightened. This reduces the burden on the traction machine. 1/5 the weight of steel floors panels has be achieved (in-house comparison)

Double-decker elevator with inter-floor adjustment function

By having a double-floor car, the transport capacity rises by approx. 190% during peak hours.
The inter-floor adjustment function allows the double-decker elevator to be adapted to buildings with varying service floor heights.
