External elevators are elevators that can be installed on the front of a building as a self-contained unit. The elevator is placed on the front of the building and has many advantages, including that it is not restricted to the narrow space of the building, for example, you have several options in terms of space and can be installed without the need for major renovations or cracking in the building. A self-supporting column is also installed in which the elevator is installed and can be installed in a short time and allows movement on all floors from the ground floor to the last floor.
