Schindler Unveils Solar Powered Elevator

Jessica Lyons Hardcastle

Schindler has launched an elevator that can run exclusively on solar power.

Inspired in large part by its partnership with the revolutionary Solar Impulse project - the zero fuel airplane aiming to fly around the world propelled only by solar energy – the Schindler Solar Elevator is a hybrid system designed to supply up to 100 percent of the elevator’s power needs from rooftop solar panels and a hybrid energy manager that stores the solar energy in batteries until needed.

During normal situations, solar panels can supply most of the Schindler Solar Elevator’s power requirements, which will vary depending on size and daily traffic. Backup power needs are provided by a one-phase grid connection that the company calls “significantly simpler and less costly” to install and operate than the standard three-phase connection.

The new solar elevator system uses a standard Schindler 3300 gearless machine room-less elevator, which is already up to 60 percent more energy efficient than hydraulic elevators. The elevator system includes many features that are designed to save energy and reduce costs: stable start; a frequency converter with an energy efficient standby power mode; controls that automatically switch car lights to standby mode and LED car lights.

In December last year, the Otis Elevator Company won a contract with W. E. O’Neil Construction to replace 24 elevators at Los Angeles International Airport with its Gen2 energy-efficient elevators and to modernize 29 additional elevators at the airport. The Gen2 machine room-less elevator reduces energy consumption by up to 50 percent compared to conventional systems, according to Otis. In addition, the Gen2 elevator reduces the system’s environmental impact because its patented polyurethane coated-steel belts, gearless machine and roller guides eliminate the need to apply lubrication. The project is slated to be complete in early 2016.

In March, ThyssenKrupp Elevator Americas released details of an energy efficiency upgrade it performed on two elevators in the 20-story Hyatt Place Hotel Waikiki Beach in Honolulu, Hawaii. The elevators originally installed in 1974 were upgraded with high-performance gearless drives, modern control systems with energy recuperation, and energy-efficient LED cab lighting. A before and after analysis shows energy consumption was reduced by 56 percent and both drive performance and ride quality were significantly improved.

  1. Retrofitting of existing 4 Lifts

    Dear Sirs:

    We have 4 very old Schindler Single Speed Lifts (2 Passenger and 2 Flat bed cargo) age 35 years

    old. Even though this is 40 years old technology but they are still working.

    It is a 13 story building but the lifts stops only at:

    Passenger Ground + 6
    [G 3,5,7,9,11 and 13 floors]

    Cargo Ground + 6
    [G 2,4,6,8,10 and 12 Floors]

    Due to Safety and modernization, now we need to renovate these 4 Lifts except we shall only keep the

    cabin, door panel, guide rail, door frame and counter-weight, other all items need change to new as

    specified below.

    Kindly send your proposal for provision of the following latest components for us to do the

    Renovation job.

    We have 220V 50 HZ current electricity.

    1) Elevator gear and / or gearless machine.
    2) Control panel with latest inverter.
    3) Door locks and door closers
    4) Inside & outside call panels.
    5) Door locks opening Cam
    6) Traveling cable
    7) usage of a frequency converter with automatic stand-by function
    8) Switch off lights, fan and other lift components when not in use – Sleep mode

    MOTOR should be – PERMANENT MAGNET MOTOR
    Traction Machine – GEARLESS, Regenerative Drives & modern controllers
    Motor Drive – VVVF2 Control
    Control Circuit – Microcomputer
    Power consumption- 30% (70% savings)

    Energy Efficiency Please use latest most energy efficient technology, low power consumption and

    maintenance. Energy efficiency is key these days so the introduction of regenerative drives are

    becoming popular by acquiring energy from the lift movements and so being more energy efficient. Taking this opportunity when you have announced Solar operated Elevators, we would like to have this option to convert our lifts to save electricity costs.

    Please include for replacement.

    Kindly revert with your best proposal which must be cost effective.

    Thanks / Best Regards

    Dr. Saleem Siddiqi
