German elevator company ThyssenKrupp has introduced new MULTI elevator technology, as a transport solution for mid and high-rise buildings.
The technology reduces the elevator footprint and peak loads from the power supply in buildings and increases transport capacities, as well as efficiency.
According to the company, several cabins in the same shaft move vertically and horizontally, allowing buildings to adopt different heights, shapes and purposes.
MULTI design has the capability to house various self-propelled elevator cabins in each shaft, running in a loop and increasing its transport capacity by up to 50%.
This would reduce the elevator footprint in buildings by as much as 50%.
ThyssenKrupp Elevator CEO Andreas Schierenbeck said: "As the nature of building constructions evolve, it is also necessary to adapt elevator systems to better suit the requirements of buildings and high volumes of passengers.
"From the one dimensional vertical arrangement to a two dimensional horizontal / vertical arrangement with more than one or two cabins operating in each shaft, MULTI represents a proud moment in ThyssenKrupp's history of presenting cutting-edge transport technologies that best serve current mobility needs."
MULTI, which includes new features such as new and lightweight materials for cabins and doors, is based on the concept of ThyssenKrupp TWIN's control system and safety features.
The result will be a 50% weight reduction as compared to standard elevators, as well as a new linear drive.
Compared to conventional lift systems, the new elevator technology is said to require smaller shafts and can increase a building's usable area by up to 25%.
The system is not constrained by a building's height although the ideal building height for its installations starts at 300m.
MULTI operates on the basic premise of a circular system such as a paternoster and comprises various cabins running in a loop at a targeted speed of 5m/s.
"To get this groundbreaking product onto the market our new test tower in Rottweil, Germany, provides the perfect test and certification environment," Schierenbeck added.
"The tower is set to be completed at the end of 2016 and by this time we aim to have a running prototype of MULTI."
