An elevator is disclosed. The elevator comprises a first upright U-channel guide rail parallel to and opposing a second upright U-channel guide rail. The elevator also comprises a slider with a first side and an opposing second side, wherein a first wheel is attached to the first side and a second wheel is attached to the second side. Some embodiments may comprise additional wheels. The first wheel rolls up and down within the first guide rail, and the second wheel rolls up and down within the second guide rail. A platform extends from the slider. The elevator also comprises a hoist mechanism and a closed loop lifting cable attached to the slider. The hoist mechanism is configured to move the lifting cable and thereby, in cooperation with pulleys, to lift and lower the platform. Preferred embodiments also include a centrifugal brake system and walls and a ceiling on the platform.
