ABSTRACT:
An elevator for traveling on a rail attached to the outside of a high-rise building supports a telescoping arm for reaching any position on or above the building. A platform attached to the telescoping arm can deliver materials to the building while under construction and thereafter be used for building maintenance such as window washing. The movable platform adjacent a building can take the place of scaffolding for a safer work environment. The telescoping arm may have various attachments for different functions including a cabin for rescuing people trapped in a high-rise during a fire or for positioning fire fighters and hoses or fire fighting equipment next to a fire.
