Last year, Hand-lift installed a turning inclined platform lift on an outdoor staircase at 420 Riverside Drive in Manhattan. The lift travels up three straight flights of stairs. The Garaventa Artira model was used to cover this great distance and to traverse the intermediate landings. The platform for this Artira parks at the lower landing. The tubes, which bend to follow the wall on the edge of the stairs, are tower mounted with a total of 24 towers. The drive box is completely hidden since it is mounted under the top staircase seven feet below the top landing. The lift has a glossy black color.
